sorry, just to add also that my sprayers and misters are only on a 24hr timer. with 15minute segments. so i am running the pump on 15 off 15. is this normal? noone seems to have addressed this situation that i can find. i know a proper cycle timer would likely be better, 1min on 4 mins off etc but i aint got one. i can build one for about £30 and will do but havent yet. are my times ok or am i way off the mark? i dont want the roots drying out but am i overwatering them? is it so that if the roots are suspended in the air and trailing on the ground as they are now, i can hit them permanently with water? i am aerating the nutrient tub so there should be oxygen in the water? or would this saturate and bring on root rot? again theres a lot of differing opinions.
thaks again in advance. any opinions are very appreciated
