Hps and Led together.

I have a heatproblem and i have done it all (two big ass inline fans, cooltube etc etc.) except buying an A/C to reduce it. So this is how i've done: I run my 400w hps on and off for 12/12, while i have my 90w led on the whole 12 h.



Does it stress my plants or is it just like i tought that the plants just think its a "cloud" passing by?

Peace

We probably need some more details here before giving any real answers? Answer these for us:

1) How big is the grow area you're dealing with (L x W x H dimensions please)?
2) What is the temp in room the grow area is in?
3) What is the temp inside the grow area?
4) What is the temp where you're getting your fan air intake from?
5) How does air move through your system?

You should be able to keep your grow area basically the same temp as your intake air if you use two fans, so this seems like maybe something other than the lights is the problem.

1) It´s about B 90x L 120x H 100cm but i keep 16 plants
2) 22-25 c
3) If and led running together for 12h it ends up to be 32 c. Nighttime- 22 c.i have the hp
4) The intake comes from the same room as the grow area is, but a window open just ouside the room and it´s a nice stream of fresh air coming from the window going under the door. I rent so i can´t cut out a hole in the wall to get fresh air from outside directly.
5) I have one fan (187 m3/h) that takes air from ouside the box trough hose-->cooltube-->hose-> out.
One( 365 m3/h) that runs carbonfilter-->hose-->fan-->hose out and in to the ventilation system.

Maybe

I probably can correct this shit all day but it´s way to early in the morning and a way to early bake for that. Will just fuck it up more! Haha!
