Hey all, this is a fantastic resource and thanks to all contributers. I was just going to get started building a bubbler but had a very specific technical question. My plan is to have a tub to accommodate two or three 6" pots. I'll probably only grow one to flowering the first time, but will preserve any other females elsewhere. I'm trying to get some seeds to germinate using the paper towel and warmth method, but am confused about the next step. I was going to use rockwool cubes in the flower pots and then surround them with some washed aquarium gravel (about pea size). My question then is, should the rockwool be sitting on the bottom of the pot, exposed directly to the liquid in the tub? Or should the rockwool be sitting on a bed of gravel at the top of the flower pot, with the gravel on the bottom inch of the pot submerged? Or am I missing it completely? Thanks for any help...
HIGH All, welcome to The City thrillhelm51. The pot stays out of the solution (around an 1" or 2) and the medium should be surrounding the rockwool. Hand watering it for a few days is needed till the roots hit the solution. I wouldn't leaf the pot in the solution because the rockwool would stay wet and then maybe end up with root rot.
