Deep water culture systems are effectively active versions of Kratky systems. They feature a single reservoir filled to the top with nutrient solution. Plants sit in net cups that are slotted into holes in a Styrofoam sheet that floats on the surface. Unlike the Kratky method, deep water culture systems don’t need to maintain an air gap to allow the upper roots to breathe. Instead, the system uses an air stone to continually aerate the solution.

White Widow is a perfectly balanced hybrid strain that features 50% indica genetics and 50% sativa genetics. She was created using parent strain White Widow S1, and provides a well-balanced high that stimulates and excites the mind whilst relaxing and stoning the body. A THC level of 19% ensures a powerful psychoactive experience that lasts several hours. These flowers contain a terpene profile that emanates grounding tastes and smells of earth and pine.

Coco coir is a good sustainable option for a growing medium. As the fibre from coconuts, coco coir allows for good aeration and moisture retention. Coconut fibres are also known to protect roots from infection due to the presence of plant-stimulating hormones.

Hydroponic plants require the same nutrients as their soil-based counterparts. The easiest way to go about feeding your plants is by purchasing hydroponic nutrient solutions that contain all of the required substances for both the vegetation and blooming periods. Products will also describe how often to add nutrients back into your system and how much dilution is required.

Now that you’ve selected a growing medium, it’s time to choose which type of hydroponic setup to use. All systems are similar in that they utilise a nutrient-enriched water solution. However, setups can vary widely depending on factors such as water exposure and circulation. Most of the following systems can be purchased, but those with DIY skills could easily make them by using buckets, drills, pumps, and air stones.

Aeroponics is perhaps the most futuristic version of hydroponic growing, and uses misted water dispersed through the air to optimise aeration and hydration. Plants are placed into the top of a large tank of water filling the bottom 25%. Under the water is a pump that sends water into misters underneath the root systems. This fine mist constantly soaks the roots, allowing plants to receive massive quantities of air and water simultaneously.

By using an automatic irrigation system, either recirculating (the nutrient solution is reused) or waste-to-drain (the excess nutrient solution is not reused), the cannabis plants are optimally supplied with nutrients. When using expanded clay, it is imperative to stabilise the pH of the substrate to avoid problems with the pH during the grow. If the expanded clay is not stabilised, many difficulties arise for the plants, and they will not be able to absorb the nutrients sufficiently. Also, in recirculating systems, when using unbuffered expanded clay, there are fluctuations in the nutrient tank, which can also lead to over- or under-fertilisation.

One of the first things you need to do is choosing a growing medium — this is a substance that supports the axis between the stem and roots. The growing medium allows the roots to descend into the water to access nutrients. There are many types of medium, each with its own set of advantages and disadvantages. It’a matter of experience to see which is best for you.

Advantages of growing hydroponic weed

It is essential to point out that in these systems, the roots are exposed to the air, and constant irrigation is necessary so that the plants can develop without problems and do not dry out. As soon as a lack of moisture stresses the roots, they are severely damaged because they have no protection as in Coco substrate, in which the root ball is less exposed to the air and therefore dries out much more slowly than with expanded clay. On the other hand, if these factors are under control and no mistakes are made, the growth really explodes in such a hydroponic system.

The following list encompasses all the apparatus you need to build a basic indoor hydroponic system. We recommend buying each item separately at the lowest possible price, so you have more funds for expensive but essential lighting and heating.

All systems use a water solution enriched with nutrients. However, some installations vary according to various factors such as circulation and water exposure. You can buy hydroponics setups online, or you can save money and build one yourself if you have DIY expertise.

I thought hydro plants liked it cold?

Although there may be more oxygen dissolved in the water at lower temperatures, at least in my grow tent that apparently isn’t the limiting factor to growth, because plant growth speeds up at warmer temperatures.

If there’s no germination at all…

Make sure to always keep the Rapid Rooter moist but not soaking wet.

The Rapid Rooter in this picture is a little too wet, which makes the seedling prone to “damping off.” If you ever notice the Rapid Rooter actually looks wet or shiny, it’s too much water. Try turning the top-feed off every few hours, or hand-watering the seedling at first. Too much moisture can kill!

Don’t use a humidity dome on seedlings unless it’s very dry where you live. If you do use a dome, consider keeping a vent open and watching the humidity. A young seedling doesn’t require high humidity, and they tend to get “wet feet” and stop growing in constantly wet conditions.
