I've never done it that way, but I would assume you should water the top bucket, just as before ... in the ground, you would still be watering 'from the top', regardless of what is beneath, so I see no need to change ... just a guess ... :smokin:
the image reaper Reviewed by the image reaper on . Pot Stacking... Ok, apparently either I get too busy, or too lazy. Here's the background... I ran a grow thru to harvest. (Indica dom - 5 gallon pot) After harvest, I flushed well, and trimmed remaining foliage for a re-veg in the same 5 gallon pot. I do this with virtually every grow, picking the finest example of the run, and re-vegging for clones. I re-vegged for about a month, and she was ready for the flower room again. When I switched her (around 6 days ago) I transplanted into a 7 gallon pot. Rating: 5
