you are right i should have left instructions......"IF" we had not gone over 1000 times, and "IF" they were even supposed to mix the water.... All they had to do was dump the water from a 20 ltr jug to the 4 litre botlle we use, then water... no mixing, not even any thinking really i mean it should have been too easy....and just my luck im on night shift all week and when im home the light is off.... So I take it "not" to change the lighting obviously to get in there b4 work?? should i be flushing them constantly or will they get overwatered???
