In our experience, we’ve tried pretty much every seed germination material from simple water, paper towel wrap, seeding mix, perlite, rockwool, sand, agar, egg shells, triple mix, coco, peat pucks, direct in soil, test tube with cotton, … I could go on.
2 years running and hundred of tests later, Spongepots are truly something unique and reliable.
Cannabis Seeds in Spongepots
If you’re buying seeds, especially cannabis seeds, they can be expensive, and its a royal piss off when your own mistake in propagation material causes a gardening failure. Spongepots are really the next step in ease and reliability in my experience.
Steps are simple:
- Buy spongepots
- Mix bacto that comes with spongepots in 1 liter of water
- Push the seed into the spongepot, moving the seed down approx 2 times as deep as the seed is wide. Use a pencil or chopstick
- Put spongepots on top of a container filled with perlite or hydrocorrals (I know the pick has hydrocorrals, perlite works better)
- Pour bacto over seeds in spongepots allowing a bit of overflow into the perlite
- Create a plastic bag dome over the spongepots
- In spongepots seeds usually crack open in 1-2 days
In our experience, sprouts may become rootbound in about 4 days, so watch carefully. Spongepots are also cool in that they move well to all other mediums when you are ready to transplant.
