Hi,
I have a small growroom 1x1x2 mtrs. 4 plants growing - currently into 3rd week of flowering. Plants are approx 1 mtr tall. The 400w HPS is now at max height 40cm above tops. The temp at the top of the plants is 28.5 C and at the root level is 21C. You see a lot of info about grow temps but I have come accross nothing telling me about ideal difference twixt tops and roots. Anyone got info on this?

Cheers,
Bastun
