hydroponic marijuana seeds

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

If your seeds still aren’t sprouting and growing properly, consider the following factors.

Add your Rapid Rooter(s), and fill around the edges with extra clay pellets to hold each one in place.

Gently place the germinated seed inside, root down

When this happens the shell usually falls off on its own as the seedling grows!

Wicks are used to passively transport nutrient solution to the roots. One end sits in the nutrient reservoir and the other in the growing container. Wicks pull water from the reservoir to the roots using capillary action.

Perlite is a volcanic glass that expands when exposed to high temperatures. It’s often used in garden soils to provide aeration, which is exactly why it’s beneficial to use as a hydroponic growing medium for cannabis.

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.

3. Prepare Your System to Ensure a Successful Grow

It depends on what system you’re using. Kratky systems don’t require any hand watering at all. Wick systems that use soil are often superior to hand watering, as the slow and steady delivery of water into the medium helps to reduce overwatering. However, they sometimes fail to provide enough water to large and thirsty plants, meaning growers may need to occasionally intervene with a watering can.

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.

If you’re drawn to active hydroponic systems, you have plenty of options to choose from.

There are numerous types of passive hydroponic systems, but the Kratky method and wick system are two of the most popular.
