In this video we do a controlled experiment comparing rockwool cubes vs rapid rooters for starting off cannabis seeds.

I’ve heard a lot of people swear by rockwool cubes and when I saw them at my local hydro store and didn’t see any rapid rooters, I thought they knew something I didn’t so I got them to test out for some hydro plants.

This was my first time using rockwool cubes and I would never have tried it if I stuck with soil.

Check out the results in the video. (spoilers at 1:45)
