So I dropped my seeds into a glass of water the other day, and all my seeds have a taproot coming out. Yay for 100% germination rate. However, none of the tap roots are very long at all. Not even the length of the seed. So, my question is, when do I take them out of the glass of water, and put them into my rockwool? I have a bubble bucket type hydro grow kit, with a HPS light, complimented by some CFL's from a previous grow. Cliffnotes: How much of a taproot should I let develop in the glass of water before moving the seeds to rockwool?
