Thanks zandor,the reason for the light cycle is the heat but also thought i might be wasteing light and power.
I have white walls for reflection , have no heat problems plants look good ,no cool tubes i do have the inlet fan ducted towards the 1000 watt hood.
The lights are side by side so the plants expand past each side of both lights ,i am bending this time under wire,so some plants will get more of one light than the other.
the temp is peaking at around 38C max and 18C min sorry dont no F and around 85% humidity max and 50% min.
Well the buds are looking good after not even 3 weeks of flower. So it is good to no i am not wasteing light.Am very interested in your comments.The reason i ask mainly is that i no u can run just the one 400watt in the same area but will i get better results useing the extra light...thanks man
Ps sory about whinging in the other thread yesterday i had had a shit day (no excuse)I am not usualy like that.Much respect.
