Yes, the pipe on the side is for water level. I'm not sure if the mist will keep the roots wet enough, we'll see. What I'm worried about is when I go away for a weekend or so. I don't have anyone to check in on them. Oh well, it won't be for awhile, around 4/9 or so. How would it work with the two in one pot, wouldn't they get crowded. I do have rock wool to put them in. I think I may have room in the grow tent under the hps with the bag seed plants. You don't think they will stretch? Maybe I can add some cfls to the sides. Well, you got me thinking of rearranging things, thanks for the suggestions.
