how to start seeds after germinating for dwc cannabis

Cannabis seedlings just getting their bearings – try to avoid moving or disturbing them until they are growing fast, with new leaves every day!

Supplies Needed

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!

Gently place the germinated seed inside, root down

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

These seedlings are a few weeks old, and the grower plans to move them all to the

Just follow these instructions and you’ll end up with healthy, fast-growing plants that germinate in just a few days. It’s pretty much fail proof!

Within 4 to 7 days (up to 14) you should see marijuana seedlings poking out of the cube.

A deep water culture setup is excellent for the personal use marijuana grower. Starting marijuana seeds for this cannabis growing method is rather easy. This method is excellent for germinating marijuana seeds. Start with standard rockwool cubes. Soak them in water.

Poke the marijuana seed in the rockwool cube where the hole is pre-made. If you find that’s too big for your marijuana seeds, turn the cube over and poke a smaller hole.

Type: sativa
Yield: 400 gr/m²
Flowering period: 8 weeks
Grow Difficulty: easy

A few hard shakes will release plenty of water. Making air pockets within the cube itself. These air pockets are very important for marijuana seed growth. By shaking out the cube you keep your marijuana seed from soaking to death. too much moisture will kill marijuana seedlings.

When this occurs move the cubes to a 2 gallon rooter DWC bucket with 3″ net pot holes with a few rocks on the bottom to support the cube. Leave plenty of space for the roots to grow.

Get your marijuana seeds ready. When your cubes have soaked up enough water take them to a bathtub. Give them 2 or 3 hardy shakes. DO NOT SQUEEZE OUT!

When you get the most of the water out, pick the seeds you want to grow and drop them in the hole about 1/4"-1/2" down. Carefuly squeeze the hole closed and place in a humidity dome. Light isn’t all that important until the seed sprouts, however its very important to keep the temps around 80*f in your grow area. Warmth will speed up the process considerably as will a few drops of Superthrive per gallon of water.

When you think your cubes have soaked up enough water, take them outside, or to the bathtub, and holding it loosely, give them 2 or 3 hardy shakes. (DO NOT SQUEEZE OUT!) This will release LOTS of water from the cube, thus making air pockets within the cube itself. These air pockets are very important for seedlings and clones. Also, by doing that, you keep your seed from soaking to death. too much moisture will kill the seedlings.

Start with standard rockwool seedling cubes. Soak them in pH adjusted RO Water, and then get your seeds ready. You can germinate them in paper towels, gauze, cheesecloth, or just do like me, and not fool with all that– just poke the seed in the rockwool cube where the hole is pre-made. If you find that’s too big for your seeds, turn the cube over and poke a smaller hole.

Within 4 to 7 days (up to 14..) you should see seedlings poking out of the cube– this is where I really watch whats happening as the TAP ROOT will grow faster than the plant itself. When this occurs, I get them ready to move to a 2 gallon rooter DWC bucket with 3" net pot holes. I will take the seedling, and place it in a 3" netpot with a few rocks on the bottom, as to support the cube, and leave plenty of space for the roots to grow without letting them lay on the bottom of the humidity dome’s tray. I try to suspend the roots as long as they are in the dome. When I feel they are old enough (when there are a FEW small roots poking out of the RW cube) I will place the 3" pots with the seedlings in them, in the rooter bucket for about a week sometimes two if I am using fluorescents for vegging.

In that time, I will have a 5 gallon bucket ready, and I will carefuly try to weave as many of the roots thru the holes of a 6" net pot, and like with the 3"er, I will place a small amout of rock on the bottom of the pot to suspend the roots, and allow ample space for more roots. I place the 3" pot into the 6" pot and then fill up with rocks, finally covering the 3" pot (kind of like a BOG double pot method for soil) and placing that into the lid of the 5 gallon bucket.
