Yeah I have been looking at the pics and thinking about it and there really is no other way. Root rot is way worse than stressing them out a bit. I would probably even go so far as to change as much as you can of the soil without screwing with the root zone too much. I dont believ there is gonna be much of any root ball yet as compare to a five gallon container. I feel bad for ya cuz when I started growing I knew pretty much zero other than the basics of growing any plant and have never run into any problem worse than under watering and some guys get hit pretty hard right off. It sucks but it looks like you are on a good solution. Good luck. Oh maybe for your first watering or 2 go with 2 Tbs. per gallon of peroxide to help with any rot that may already be there.i agree with sticky bob theve been waterlogged for almost 2 weeks now but the soil deffinatly isnt bad, nutes i should deff hold on till i get this drainage problem fixed, but i might have to go with sticky on this one and try and change the soil now before root rot occures i think its prob worth the risk and even if the roots are exposed to oxygen when i more them isnt that a good thing i have a dwc thats running perfectly and i heard its good to give the roots a breath of fresh air every now and again the onlything i have to worrie about is the roots ripping or tearing in the transplant right?
