Well my system is up and running i have four plants in a flood and drain and a duel spect 400 w hps.The plants are only 4 weeks old.And the light is about 3 ft away.I lowered the light and burnt the leaves they went a yellow colour
and some of the smaller leaves shrivled up.Will they be ok they are still growing.
How long should i flood it for and how long should i keep it dry ?i have had it on 1/4 splells..and also i'am a bit concerned about the temp of the res,i,am using a heat mat and its been on 24 7.When i went to check it before the temp was at 33 c it felt a bit warm to say the least..What temp should my res be?
And also iam using a black cover but light is still hitting the top of my rockwool cubes and ive noticed algea on all 4 ive took it all off now,, is this ok? they is no algea in the res.
also would it be better to have a moving fan and get light closer or should i wait till they are bigger.
I really apriaciate all the help you's give.
Thanks inadvance cron
