Hi Jamromhem,
Thank you for the suggestions which I'm going to try. Rockwool just stays too wet. Coco looks great, but this poly seems as though it would be perfect for my tomatoes which will be on a
drip system. I agree with GPS that I wouldn't reuse the poly for fear of embedded organic pathogens.
Do you surround the poly with anything heavier (e.g. hydroton or river rock, etc.) for physical support of your plants?
Thanks!
Paul
