Learn How to Start Seedlings So You Can Grow Hydroponic Cannabis Plants Like This!
There are a few different ways to get cannabis seeds, with the most common being ordering seeds online and growing seeds you find in weed that you buy. Learn how to research and find the right strain.
Here are tips for taking the best care of hydroponic marijuana seedlings:
Just like in soil or coco, cannabis plants in hydro grow fastest when it’s a little warm, around 75°F!
Most seedling plugs will go back into place easily, and you’ll barely be able to tell it’s been opened 🙂
Rockwool is also a common choice and is a substance made from spinning fibres from basaltic rocks into a wool texture. Rockwool is really good at retaining water, which enables proper hydration of the top root system. However, it is not very environmentally friendly and is also potentially harmful to your health.
Liquid food needs to be mixed with a certain amount of water. If the plant then absorbs water, it also absorbs nutrients, allowing it to grow.
Hydroponics allows you to control the nutrients your cannabis plants need completely. Dilute them with water and add them to the tank so there is zero waste, unlike adding nutrients to the soil which is comparatively ineffective as some of the nutrients always fail to make it to the roots. You can calculate accurate nutrient measurements to guarantee that your weed plants receive exactly the right amount each day. The risk of root burn from inadvertently giving too much fertiliser is eliminated. Many strains of cannabis plants require a correct pH value to grow properly, and again, hydroponics ensures that the guesswork is removed when it comes to testing the pH value.
Best hydroponic system for weed
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.
A hydroponic setup uses less space as the soil needs a lot of space for the roots. You can group your plants more closely together, and more plants mean more weed, once the flowering season begins! It’s also less messy than a soil-based system, no need to spend ages sweeping spilt compost from floors.

Observing the root system is an excellent way to spot signs of nutrient deficiency or stress as problems are usually revealed more rapidly than the parts above ground. If the roots are not white, you need to take action – brown or dark roots are only seen in unhealthy plants.
Strain selection is an important factor of hydroponic growing. Plants grown within these systems are free to uptake nutrients extremely fast, which often results in explosive and rapid growth. For this reason, selecting a large, towering sativa variety won’t be your best choice, especially if your system resides within an indoor grow tent.
As one of the most popular options, clay pebbles are excellent at aerating root systems. Clay pebbles sometimes require that growers alter the pH in order to provide an optimal growing environment, however, pre-altered pebbles can be purchased. You’ll need to place clay pebbles into a plastic hydroponic basket that has spaces for roots to grow through.
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.
C) Provide The Correct Quantity Of Nutrients
The wick system features a growing container filled with a medium and a separate reservoir that houses the nutrient solution. Some growers choose to fill the growing container with soil, whereas others opt for soilless media such as coco coir. These growing media feature gaps that allow oxygen to enter and aerate the roots—removing the need for an air pump.
You’ll need to constantly test the pH of the water to ensure an optimal growing environment. Nutrients are more available to plants when the environment is slightly more acidic. Therefore, a pH of 5.5–5.8 is required. Use a pH testing kit to take regular readings, and be sure to change the solution weekly to maintain this range. During flowering, a pH of 6 is preferred.
Now that we have covered the history and benefits of hydroponic growing, it’s time to get things started. To begin, you’ll need to select a growing medium—a substance that will hold in place the intersection of the stem and roots. From this location, the roots will grow down into the water in search of nutrients. The inert medium also allows good air access to the top of the roots. There is a huge list of different media used by cultivators, with those below being the most common. Each medium has its own unique benefits, and some work better with different systems. It’s all about experimentation when starting out to see which works best for you.
