growing hydroponic weed from seed

Just like in soil, cannabis plants in hydro tend to grow faster in relatively warm temperatures. This is a somewhat controversial statement because a lot of hydro growers prefer to keep their temperature lower in the grow space to help prevent root rot. In fact, there are some growers right now who are reading this and shaking their heads at me.

The other reason I recommend to keep it warmer is because the plants just grow faster around 75°F in hydro. If your roots go from 60°F to 75°F, you’ll see the plants start growing faster in just a day or two, just like how plants in soil grow faster when it’s warm!

If you haven’t put your hydroponic system together yet, now is the time! Make sure your pumps are all running, and that you’ve made a reservoir with seedling-strength nutrients. You need a home to put your new plants!

Supplies Needed

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

We have a cannabis seedling germination page which has everything you need to know about all the different germination methods, but this tutorial is different. In this hydroponic seedling tutorial I’m going to share exactly how I do my seeds from beginning to end in a DWC/bubbleponics setup!

Potency: Once you harvest the buds, there’s a good chance they’ll be more potent than if you had grown them in soil. Some dispensaries even charge a premium for buds grown in hydroponic systems.

If the pros of hydroponics outweigh the cons, you may be ready to try your hand at employing this growing medium in your home.

Monitoring: Part of the time investment involves near-constant monitoring of the garden to ensure the health of the plants. If one cannabis plant in a hydroponics system becomes diseased, the entire crop may fail and die. Damaging microorganisms also thrive in wet environments and could threaten the health of the plants before harvest time.

What are the benefits of hydroponic growing?

Water conservation: In rain-deprived places like California, water conservation is crucial. A hydroponics system may use 20 times less water than traditional soil cultivation. Water in this type of growing medium can be reused, meaning that none goes to waste.

Space saving: A hydroponics system is a major space saver that may require 20% less room than soil cultivation.

Year-round growing: Hydroponics systems can thrive in a variety of environments, but an indoor garden is especially desirable as you can grow your cannabis plants year round.

Differences Between Soil & Hydro

Hydroponics is when you grow your cannabis plant in an inert medium like coco or a reservoir of water, and provide all the nutrients to the plant directly in the water.

Benefits of Hydro Over Soil

Growing in coco coir can be considered a type of hydroponics since it naturally contains no nutrients and you must provide all the nutrients in the water. However, when you say “hydroponics” most people think of this:
