d) Hydroponic reservoir and tray
Hydroponic systems are either active or passive, depending on the way they are designed. Active systems involve the movement of nutrient solution using electric pumps and the oxygenation of water using air stones. Passive systems are much more simple, and some rely on capillary action instead of electric pumps to deliver nutrient solution.
Materials Needed to Make a DIY Hydroponic System
i) Ventilation fan and ducting tubes
Every hydroponic system requires frequent maintenance to provide an optimal growing environment. Below are all of the major factors you need to be aware of.
The Kratky method makes hydroponic growing affordable, accessible, and easy. Growers can use a range of items to make these systems, including buckets and plastic boxes. The plants sit in net cups inserted into a lid, and the roots reach down into a nutrient solution below.
I n the previous post, we gave an overview of hydroponic gardening including its origins, the various systems and techniques, and medium options for a hydroponic grow. In this next article, we will focus how to use hydroponic systems specifically for growing cannabis.
A benefit this setup offers is that it can easily be expanded as you want to grow more plants as long as your reservoir has enough capacity to provide all the plants with enough water. To expand a drip line setup, all you need to do is add additional lines to the new pots.
Set Up Your Hydroponic Cannabis Growing System
There are numerous setups for growing hydroponically with varying benefits that were discussed previously here. And while there are several types of hydroponic setups that don’t use any type of growing medium at all, many of them still use some sort of substrate to support root growth.
Once you have gathered your materials you can begin to construct your hydroponic setup.
When growing hydroponically, you are responsible for providing all of the nutrients necessary for plants to survive. Nitrogen (N), Phosphorus (P), and Potassium (K) are the three essential nutrients for plant growth known as macronutrients. Additionally, there are secondary and micronutrients that will help the plant develop as well. These include Boron, Calcium, Copper, Iron, Magnesium, Sulfur, and Zinc.
I’ve tried a bunch of different germination methods over the years, and the technique I prefer is for hydroponics is starting with the “Paper towel method” to germinate, putting the germinated seeds into Rapid Rooters, and installing the Rapid Rooters directly into reservoir. Lots of other germination methods as well, but this has worked best for me!
