Using two HPS 600W lamp. Sometimes gets short interruption of electricity and they turn off. My question is what will happen if I'm not around and don't turn them off? Is it possible to ignite and what fuse should I use in this case?
Thanks!
Stop grow nutrients. Check your Ph meter - it could be low Ph. Grow nutrients + low Ph = nitrogen burn leaves. I think thats the problem and curling down leaves becouse of too much water.
