Homegrown hydroponics is a significant affair needing patience and persistence. Note that hydroponics plants are limited to terrestrial plants.

However, you would be aware that this is something that doesn’t require soil. While there are many benefits of actually utilizing this process, you have to remember unless good care is given, there is a possibility that the plants could in reality die off.

There are also other hydroponics systems that make full use of recycled material for nitrifying the plant containers. This procedure can indeed be cost effective when you consider a sensible method in which you can sort this out. On top of that, you will come across quite a few testimonials that is going to state that lots of plants may be grown with the drip feed setup. This is something which you need to really look at since this is a cost effective method that is applicable to homegrown hydroponics.

Truth be told, what you ought to ideally do is gather just as much details as possible. The more data that you have with regard to practicing hydroponics in your own home the better geared up you’ll be with regards to ensuring this exercise is successful. As mentioned previously there’s a lot of information that’s available for your perusal on the net.

When you genuinely contemplate it, apart from the data on the net, it’s also possible to collect a great deal of data from numerous news letters and manuals from selected garden societies. This can be definitely a great way to pull together data since you will be able to additionally directly talk to fellow gardeners who are in tune with hydroponics.

I really like publishing content pieces on hydroponics and gardening subjects such as this, but there are other subjects that I enjoy writing about as well. One of these topics is cheap homemade hydroponics.

 Ideal pH for Plant Growth

 Different pH levels are recommended for each and every plant. Attention to research should be done to ascertain the proper pH level for your plant. Findings however have found out that a pH level of 5-7 is safe for most plants, 6-6.5 being the most ideal.

 Be Careful When Handling Chemicals

 Solutions having a pH of between 3 and 10 are usually safe for handling. Caution is advised for solutions outside this range as they would likely be strong acids or bases. Gloves and goggles are advised as a precautionary measure every time you work with any type of chemical.

 Controlling pH Level

 Checking pH levels should be second nature when nutrients are introduced to your solution. When solutions acid levels are observe to be always high, solutions should be changed more frequently. When nutrients are absorbed by the plant, this action makes the solution acidic and leads to nutrient “lock up.”  pH level are signs of nutrient deficiency, be sure to constantly check them. Check your water this may be the cause and not the nutrient solutions.

Various types of pH test kits are available in the market today. Some are fairly accurate with the more expensive one showing an increased degree of accuracy. Litmus paper and liquid pH tests kits used in swimming pools are an inexpensive way of measuring pH. This works for most of the plants, but plants with more sensitive pH reactions require more elaborate ph test kits. pH UP and pH DOWN chemicals are used to adjust pH levels in your nutrient solution

Perlite has been known for years as soil additive and growing medium, used to increase aeration and soil drainage. Perlite belongs to mined materials, originating from volcanic glass. This natural material breaks into multiple tiny bubbles, when heated rapidly above 1600 deg. F.

Being one of the best hydroponic growing media, perlite is usually used by itself or as a component in mixtures with other mediums. Often it is vermiculite, which is mixed with perlite in equal proportion. Besides, perlite is often used as the major ingredient of soilless mixtures. Perlite is characterized with good wicking ability and thus it is commonly used in wick-type hydroponic systems. Finally, perlite is a relatively inexpensive growing medium.

The biggest weak point of perlite is that this material cannot hold water long enough. It means that perlite growing medium dries out quickly and requires more frequent watering. Besides, perlite dust can be harmful for human health, and it is recommended to wear a protective mask while working with it.

Vermiculite

Being another mined material, vermiculite resembles mica rock in its natural state. Under the influence of high temperature, this material breaks down into small parts just like perlite.

It is a common practice to use vermiculite in conjunction with perlite in hydroponics systems, since these two ingredients complement each other. Vermiculite is capable of retaining high volumes of moisture (up to 200% – 300% of its own weight); and since perlite cannot hold water that well, it is easy to balance your growing medium, so that it holds water and nutrients, while still supplying enough oxygen to plants roots. Usually, a 50/50 mixture of vermiculite and perlite is used for hydroponic systems of drip type, as well as for ebb and flow systems. Similarly to perlite, vermiculite is also an inexpensive growing material.

The major drawback is that vermiculite retains too much water. This material should not be used by itself as the only component of growing medium

In most cases, either phosphoric acid or potassium hydroxide is used to adjust pH level of the hydroponic nutrient solution. The first substance is used to lower pH level, and the latter, consequently, is used to raise it. Being relatively safe and usually sold diluted, both of these chemicals should be handled with care, avoiding direct contact with skin or eyes. When you choose to use concentrated pH adjusters, be very accurate, because significant pH changes may lead to devastating effects on your garden.

Along with the above mentioned chemicals, there are also some other pH adjusters for hydroponic nutrient solutions. For example, nitric acid and sulfuric acid can be used to lower pH level, however, being much more dangerous chemicals, these should be handled with extreme care. Besides, some gardeners even use citric acid to lower pH level in hydroponics system.

Before checking and adjusting pH level of the nutrient solution, always do this after you added all the nutrients and fertilizers to the water, since they can influence the pH level of the solution. Check the pH level with any method you like after adding nutrients and mixing the solution. If necessary, add pH adjuster to the solution, but use only small amounts of adjuster not to raise or lower pH level too much. It is better to achieve target pH level bit by bit by adding small amounts of the adjuster and checking pH level repeatedly.

As the growing plants consume nutrients, pH level of the nutrient solution will raise. That is why it is necessary to perform regular checks of pH level and adjust it if necessary. Keep in mind that pH levels may change differently in different hydroponic systems, depending on various factors, such as type of plants, their stage of growing, environmental conditions,

Light Movers

Of course, none of the indoor lighting systems can substitute the sunlight. Artificial light is much less intense, so it is necessary to place it close to the growing plants. However, this is also not that good, because it may cause overheating of the growing medium or even burning of the plants. Besides, when light is close to the plants, it may lead to the so-called pyramidal effect, when the plants, closest to light source, grow much quicker than those at the distance from the light bulb.

Moving plants around may be a solution for that problem. However, it is not that always easy to move plants, sometimes it is practically impossible. The only way out in that case is to move light around the plants.

Special devices, called light movers, exist to move light. There are two types of light movers: linear and circular. Linear light movers move light lamps back and forward, while circular light movers can move 2 or 3 grow lamps around the circle. Linear movers can be used in rectangular shaped garden, while circular devices are suitable for round gardens as well.

Light movers help to prevent plants burning, and, at the same time, they help to increase the area, covered with light, and to balance the light received by plants that grow at different parts of the garden. Unlike stationary light, light movers provide lighting of the plants from many angels, resulting in better light distribution.

The most essential of all nutrients for leaf and stem development. Nitrogen consumption depends on a plants growth cycle and in a vegetative growth phase of plant nitrogen consumption is greatest. Hydroponic nutrient solutions labeled as “grow” or “flower” contains more concentrations of nitrogen. Nitrogen deficiency is the leading cause of plant growth in indoor hydroponic garden systems. Yellowish, soft and weak plants and leaves are tell-tale signs of nitrogen deficiency.

Half-strength nitrogen solutions are ideal for plants between growing phases. This will prevent plant stretch while it’s switching its energy over to flower development. Normal feeding is resumed once the plant reaches the flowering stage.

Phosphorous plays a major part in root and flower development. Phosphorous deficiency signs are slow and stunted plant growth. Phosphorous is crucial to a plants flowering stage. “Bloom” type formulas contain a 0-50-30 concentration, containing no nitrogen and high levels of phosphorous and potassium.

Potassium (K)

Different in action from the previous two nutrients, it doesn’t feed the plant directly in any specific stage of growth. It merely facilitates plant intake of other primary and secondary nutrients. Potassium deficiency cause irregular plant growth and susceptibility to pests and disease. Potassium inhibits fruit production and should be lessened during this stage.

Calcium (Ca)

Facilitating and filtering the absorption of other nutrients Calcium is one essential nutrient. It is also a natural base that increases the pH level is needed. Commonly used in the vegetative phase of plant growth, calcium consumption is decreased during the flowering stage.

Mainly for chlorophyll production in photosynthesis, deficiency causes yellow leaves.

Yellow leaves are a sign of sulfur deficiency and are only used in small amounts.

Used in small amounts, iron deficiency is similar to sulfur deficiency. Yellow leaves are the general signs of deficiency. High pH causes iron absorption problems so constant monitoring is advised.

Mainly for nitrogen absorption and converts nitrates to ammonium

Boron (B)

Facilitates carbohydrate transport in the phloem, it is not essential and maybe disregarded. Boron overdose causes plant kill, it is not found in regular soils and only supplemented.

Nutrient solution is made of water with dissolved fertilizer. It is preferable to have good quality water to be mixed with the fertilizer, the amount of which is always indicated by the manufacturer. It is very important to check and adjust if necessary pH level of nutrient solution with liquid pH adjusters. Usually, pH level of the nutrient solution depends on the plant; however, most often it is between 6.0 and 6.5 for the majority of the starter cubes, with the exception being Rockwool, which needs pH level of 5.5 to 5.8. Fertilizing young plants, a gardener should use a nutrient solution as weak as ¼ to ½ of the full strength suggested by the manufacturer. Only plants older than two weeks can be fertilized by the full strength nutrient solutions. It is recommended to keep the growing medium moist, but not too wet or soaked with the hydroponics nutrient solution.      

How to Transplant Seedlings

The seedlings should be transplanted when the roots have grown out of the starter cubes. It is just necessary to place the seedling along with the starter cube on top or into the permanent growing medium, which can be any hydroponic growing medium or just soil. 

Notes in taking cutting for clones

Cutting, as a method of plants propagation, works well only if every step of the procedure is done correctly. Otherwise, experiments may result in devastating consequences. Though, when done properly, up to 95-100% of all cuttings grow successfully, it is still may be a good idea to take twice as many cuttings as needed, if you are making first steps in growing cuttings. 

One of the hints to increase chances in successful outcome is to use distilled water, while growing cuttings. Generally speaking, this is one of the most reliable and proven methods of plants propagation, suitable for most of the plants. Other examples of propagation techniques are dividing, air layering, and tissue culture. It is even possible to root cuttings without the use of any growing media in specific hydroponic systems. After forming the first roots, such cuttings are usually transplanted into any type of preferred growing media.

Defining the best growing medium is pretty challenging and disputable. It is a matter of personal likes, preferences and exact growing needs or requirements in most cases. It is like choosing a car: everyone picks the one, which suits his/her personal likes and requirements: someone chooses a small economic car for city traffic, and someone prefers powerful SUV to conquer sand and morass. Just like choosing a car depends on many factors, while choosing a growing medium it is also necessary to consider many variables, for example, what type of system is used, what plants you are going to grow and under what environmental conditions. Though there are a great variety of factors to consider while choosing a particular growing medium, it often comes to price, availability and personal preferences. 

The most common types of growing mediums as well the description of their key advantages, disadvantages, their basic characteristics and tips on general use are specified below.

Oasis cubes

 Expanded Clay Pellets

 Rockwool

Coconut Fiber

 Sand

 Gravel

Perlite

 Sphagnum Moss

 Water

Vermiculite

 Fiberglass Insulation

 Saw Dust

Soilless Mix(s)

 Air

 Lava Rock

Oasis cubes

Oasis cubes are lightweight cubes, which serves the best for plants propagation from seeds or cuttings. Pre-formed oasis cubes are commonly used by hydroponic gardeners. This type of growing medium features neutral pH level and can hold water very well.

Since oasis cubes are usually used at the first stages of plant growth, they are usually not larger than 2” x 2” inches in size. It is very easy to transplant such cubes into any type of hydroponic system, growing medium or even into the soil. 

There are many different sizes of rockwool growing media cubes. The 1x1x1.5 inches and the 2x2x1.5 inches cubes are usually not wrapped into plastic and used as seeds propagation equipment. These are the so-called “starter cubes”. Another typical size of rockwool cubes is 1.5×1.5×1.5 inches. These cubes are usually wrapped with plastic on their four sides, which helps to slow down moisture evaporation. Such cubes are recommended for growing cuttings.

As the major growing medium either 3″ or 4″ cubes are used. They can also be used in combination with some other type of growing media. If the plants are small, such cubes may work well during the whole growing process. However, for growing larger plants such cubes may be too small and need to be replaced with or transplanted into the larger growing media as the plants get bigger.

By the way, some of the bigger cubes may have a special hole of 1 inch in size to make small cubes transplantation easier. Just insert a small 1” cube into the hole in the larger cube and transplantation is over.

How to Use Slabs

Though all the slabs have depth of 3 inches and length of 36 inches, their width may be either 6, 8, 10 or 12 inches. The most widely used sizes are 6″ and 8″, since they are big enough to suit practically any hydroponics system growing needs.

Rockwool slabs are supplied sealed into the plastic wrapping. Usually, slabs are used for transplantation of small cubes into them. In order to do that, one should make X-like cut in the top plastic cover of the slab (the size of the cut should match the size of the cube to be transplanted). After that, plastic tabs are lifted aside and the cube is placed on the slab. Some gardeners fix the cube to the slab with a toothpick or small plastic spike until the roots grow into the slab.

Hydroponic nutrient solutions are normally sold in concentrated forms. They are then added to the water supply with a specific ratio. Ideally, 150-600 parts per million consists a normal concentration of hydroponic solution. Normally sold in two or three parts because direct combination is not possible. Remember to mix nutrients into water first before combining, never combine two nutrients together.

 How Much Hydroponic Nutrient Solution?

 There are specific proportions for each plant type and phase of its growth. Advances in nutrient solutions have greatly improved the precision of concentration based on a plants growth stage. Hydroponic nutrient solutions are usually sold in “grow” or “growth” formulas for the vegetative phases and “bloom” or “flower” for the flowering phase of the growth cycle. Remember to switch to the bloom formula during the bloom stager to increase yields exponentially and max out your plants capacity.

In poor growing conditions weak nutrients are recommended. Low lighting, overheated gardens, crowding and root bound plants. Weak nutrients are also ideal for newly rooted cuttings and for transporting plants or when they are in the transition of growth cycles.

Normal, healthy plants can be used with regular strength solutions in ideal growing conditions. Increasing nutrient solutions could be utilized to enhance efficiency of your gardens. An ideal system such as high quality lights, proper aeration and ventilation when present is the only instance wherein you could increase the level of nutrient solutions to improve plant growth. Gradually increasing the nutrient solution is advised as not to burn the plant roots.

Various additives are also available for optimum plant growth. Maintain good grow logs or records of types of additives used, when applied and results. This enables you to measure its effectiveness in the future. If there are any negative effects with experimentation, flush or rinse your hydroponic system immediately.

 How to measure Hydroponic Nutrient Solutions

 Electronic conductivity of dissolved minerals in the water is the usual basis for determining nutrient solution. Parts per million (ppm) is the unit of measure. But this is just a general way of measuring conductivity in the solution and not the actual strength of individual minerals. This is the main reason why hydroponic nutrient solutions are sold as a mix of 3 parts. Once the desired mix is achieved it is very convenient to change the concentration to achieve proper conductivity.

Overuse of Hydroponic Fertilizers

 Flushing out your growing medium is the first intervention once any signs of over fertilization are observed this is to prevent further damage to the plant. Clean water is used for flushing until signs of nutrient deficiency are observed in the plant. Normal feeding and schedule is then resumed. Some hydroponic systems require a top down flushing to completely clean out the plant.

2 weeks before your expected date of harvest, flushing is recommended for the plant. It is done to leave your harvest free from the hydroponic solutions taste.
