Is it too hot ??

Ok so, I have two plants under a 400w MH and my temp is at a constant 90 degrees and my humidity is 30-40% constantly. I have a good fan on so they're always moving, and they're always plenty watered. They look fine, and don't seem to be burning or anything. They are in their first week of flower, and have been this hot for a week, and seem ok but I want more than just my opinion lol is it ok to have them this hot ??

My grow cab has a 400W hps with cool tube and 250cfm fan suckin air through temps still stay high 75 in the morn and towards the end of the day 85-90 my plants are perfectly fine I do keep it open during the day to let fresh air in faster than my passive intake could allow so I would recomend getting a cool tube do you have an exhaust in your cab?

It's in a stand up shower lol so no roof and I have the bathroom fan running constantly to help pull out heat, and a little house fan in the shower to keep the plants moving. Other than raising the light I don't really know how to keep the heat down.

Oh and there isn't a fancy air cooled hood, it's actually just the socket with a homemade circular hood.

Ic I would recomend like a cooltube for your bulb or at least an good exhaust fan to take all of the extra heat out of the area the cooltube helps out a TON!!! there is a cheap DIY one on here but the pyrex bake around is just a pain in the rear to find there mite be some on ebay but if heat is an issue the best thing you can do is "Exhaust" it from the area just get a 4inch to start out with and you can go from there to accomidate your temp

Cool well thanks for your input, is there a website you'd recommend for finding those "cooltube" lights ?? Or would any grow shop know about them ?

depends where you are really you could look at greens horticultures web site ecotechnics makes coolshades depends where you live i guess

ebay homie gonna be the best prices by far got my 6inch cooltube reflector for like 50 bux ususally like 150 n the fan is gonna run you another like 50-200 bucks depending on the quality/cfm/quietness
