Hi Bear, I love my rapid rooters more than someone should but they only come in the really small seedling size unlike the RW. Does the RW have drainage issues and is that what causes the ph probs? I certainly don't need any more ph issues.

Also I just harvested my 3 plants and found that the roots were actually quite rootbound in the system and interfering with the drainage. I thought somebody mentioned drilling larger holes in the bottom of the top buckets or was that my imagination?

Feliz Navidad!
