I do DWC Hydro. My last grow divebombed, it took a little while for me to replant, I made a big mistake, I grew a strain that was unknown to me. It was a mutant, grew 8 foot tall and never flowered right. It also blocked all the light from my other plant. I only ended up getting 50 Grams dry from the second plant and none from the Giant. If I would have replanted right away it would have been enough to get my wife through until the next one was ready. But I took two months off.
I have a really small grow space, so I am only growing one at a time.
