Am I burning my plant !!

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! they have been under the light for a week now...

Your good man iv had a 600 as close as 8 inches as long as the fans are keeping the hot air moving and cool air rightt above ur plants ur good.

Instead of decreasing the lumens try upping the air circulation, will be more beneficial.

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.

OK it's done I'll just keep a close eye on em and see what happens...

My temps range from 67 to 73 was thinking to raise the light and plants so there not on the same level as the air intake to see if I can get around 78

Catchy title snappy response lol

400w at 12 inches is good

see the chart for 11500 lumens you are safe,

perhaps time to potup?

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

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..

reflection vs ventilation ..? always go ventilation

I read all tho heavyweight reflection physics books

to get the best outta light

it was air the plants needed not light reflection ..lol

avoid this most popular kommunist mistake

I have 8" pro rhino ventilation and a carbon filter the tent can even hold up, I have 6" intake 1 oscillating fan and another small fan blowing on the light all in all cost me £300 just for ventilation alone I only have a 5" by 5" tent lol its enough ventilation there !!!!
