If you zoom in and see the leaf curl on the outer edge is this because my light is to intense at 400W 12 inches above the canopy? I just backed off to 250Ws just in case!:confused: they have been under the light for a week now...

Was thinking to swop my tower fan for a standard fan. The tower fan dont move much air but I do have a 8" pro rhino fan and a 6" intake fan..

Yeh don't know how hot it is where you are but I use less for 1200w hps and am fine.
you've not got much of a problem in the picture at all think if u do as you said and scrap the tower fan you'll be fine, just concentrate the fan onto the light instead of the plants blowing towards your outtake.

Plus worth a mention, have you thought about a fan controller and thermostat, in your situation I think it would be ideal.

400w at 12 inches is good

Was thinking that to vostok got most potted but run out of soil have to order more looks like I will need a better relector also as the light spread with these huge pots won't be enough so I just ordered a probiolic shade has lots more light spread..
