Marijuana weed and cannabis seeds can get pricey so making sure you germinate them in the best way possible is required. Fortunately, they are some of the easiest seeds to germinate and force into sprouting. We have gone through countless tweaks and modifications and despite the evolution of our methods, this is still the best way to germinate seeds. Here is the PROOF that this method reigns supreme in a 7 way germination comparison.

1. Seeds
2. Water
3. Hydrogen Peroxide(Secret Sauce)
4. Rapid rooters
5. Seed Starter Tray
6. Spray Bottle

STEP 1: Add a squirt of hydrogen peroxide to a bowl of water
STEP 2: Dunk and squeeze rapid rooters thoroughly, Squeeze half the water out
STEP 3: Plant Seeds in the hole, butthole up
STEP 4: Plug it with a torn corner
STEP 5: Place them in a seed starter tray, spray the lid and seal
STEP 6: Cover and place in a warm room with 24 hours lighting.


  1. You say to leave them alone for at least 3 days. What do you do after the seeds have popped? Do you ever add more water? If so, when do you add more water? I am on day 4 and 1 of my seeds hasn’t broke through yet. How long do you keep them in the humidity dome?

    1. you transfer as soon as the main stem is like a cm long. Add more water when the rooter looks pale/dry keep em under a dome even after transfer for abouut 2 weeks

      1. Thanks for the reply. Just another quick question….in your 7 way comparison video, you busted the myth about seeds requiring darkness….so what is the purpose to plugging the hole on the rapid rooters and rockwool?

        1. They need air and medium to grow into in the beginning, otherwise, what would support the plant and allow it to stand upright?

  2. RE: STEP 6: Cover and place in a warm room with 24 hours lighting.

    I will be using Rapid Rooters in an AC Infinity Humidity Dome w/ LED Lights and Heat Pad.×8-cell-tray/

    What is the recommended PPFM Light intensity and inside temperature ranges when using the above set-up and Rapid Rooters?

    Am I understanding correctly that starting Week 3 the seedlings should be in 5 US Gallon bags of Grow Mix and moved inside of the grow tent, and after, follow your chart from then to the end?

    Thanks in advance!

    1. 200 ppfd to begin,
      you should transplant the seedlings to the forever pot as soon as the roots poke out of the rooter

      1. Thank you.

  3. Unfortunately don’t have the money for all the bells and whistles as my wife is sick so I am on a very tight budget so will this method work with just using half a cup of water covered and left for 2days or would I be better using the paper towel method? Sorry for long question🙏🏽

    1. no, I like cup of water method better. Hope she gets better fast
