I have been having heat issues and so far only 2 have died, but now everything is looking like its about to go. i am very disapointed, i added two 8" inline fans and the temp is only at 89.

and the fan on the stand is blowing in 75 degree air..... from central AC.. i want to cry

this is my emotion lol:wall::wall::wall::wall::wall::wall::wall:

is that whole room at 89 f or just the grow area? different solutions depending on which problem.

if the grow area only is what's hot, then move the ballasts out, if you haven't. increase airflow with oscillating fans. the biggest change would be to vent the lights themselves which you can do since those hoods are fitted with air vents.

if the whole area is hot, the only thing you can do is increase the a/c.

thats the whole rom temperature. i hooked up the ac to the lights... its down to 87... i have the ballasts in the same room. i can put them outside... i need oscillating fans and i think im going to get a ac unit.

i broke down and got a portable ac for my veg room. the portable works really well - the outdoor temps are in the 90's and i'm running a 600 watt hps.

don't forget you'll need to vent the a/c exhaust out of the room.

I broke down and bought a portable also, I funnel air from it in to my grow cabinet...my girls love being at 72-74 at all times..Get one, Circuit has one for $179 right now.

So , after much disapointment luck has struck me. I was able to get a 6000 btu AC unit for 25$ at lowes. It has a cosmetic dent but operates perfectly. It shoots out 65 degree air. the room is cooling right now and i think it will be very promising to see the results when i test the lights.

I have lost 4 ladies... i am very sad but will focus on what is here now. I am still learning more then i thought i ever would doing this. Ill post pictures off everything tonight and then ill update often to show you growth.

Should i get carbs ? maybe thats a very early question to ask.

Sounds like you're gettting a handle on things. & i don't have a clear idea of what you got goin on but here's what I would suggest if you haven't already done these things that is...

#1 get your ballast(s) outside the grow room, they produce heat.
#2 If you light reflector(s) are not sealed (have a lens) then set them up w/ fans to cool them.
#3 Make sure the ducting & fans cooling your lights are bringing in fresh cool air on the intake end & that the exhaust end is not dumping into the same room, run it out of the room. this cooling line should be a closed loop seperate froim the regular air in your grow room.
#4 Have a venting fan that is there to exchange the air in your grow room. should pull in fresh air & blow it out. it just needs to keep fresh air coming in & old air moving out.
#5 Another oscilating fan inside the grow room. (This doesn't have so much to do w/ cooling but it's good to keep air moving to strenthen the plants & make sure there are no stagnant air areas in the room.

If you're outside temp is 75 degrees then just doing this should get you close to that temp. If it doesn't then well I would wonder if you are actually venting your exhaust air off you light cooling line outside the room you are intaking from. If you've done all that & temp is still high you should add move cfm's to venting or cooling. Or do what you can to lower the 75 degree temp in the outer room.

If i had to guess though I would think you don't have a closed system on your light cooling. because for you to be losing plants i think your temps must be 90+. So if you do not have a reflector that is set up to be cooled on a closed loop system then it's well worth the money to get one. Get a reflector with a lens (tempered glass bottom) and an opening @ either end to hook up ducting so you can have an inline fan blow air thru their & carry all that heat away =)

he's got a point (lots of them) if that room is hotter than the outdoor temp. i had assumed you were living somewhere where it is still hot = like it is where i am

Quick point, I noticed that all lamp hoods have hook-ups for venting. So.. how come you haven't hooked them up?

If you have sufficient flow of air being PULLED out, and have sufficient passive intake openings, negative pressure means that you should only have to pull the air out, not also push it in (which utilizes more power and also creates even more heat).

i hate getting serious here, but the problem seems to be that we don;t really know what his current set up is in enough detail to help him. we're each making assumptions that could be wrong.

we need a diagram of your venting system entrepreneur.

and for god;'s sake vent those hoods.

I honestly think that venting from the hood should be the first thing handled, as that's the original source of the heat. It's also gotta be so much easier to control if you start the venting at the source.

My oldest boy grows mainly indoors, and I checked out his set-up closely. It is ALL about venting. He's got some major exhaust hooked up, not just relying on cool tubes, or really any one thing except venting and moving that hot air out.

Disclaimer: My experience with lighting is for reef tanks (not shitting you); and my experience with ventilation is extrapolated from plumbing tanks. And living in hot climates (I am the Queen of Fans).

yea, that's why i told him to vent the hoods no matter what. but after that it really depends on his circumstances. if he lives where i do and the outdoor temps are in the 90's then venting is not his problem, a/c is. he says that whole room is at 87 under a central ac system which just doesn;t seem right. soi'm thinking we don't know enuf to help at this point

don't forget to read my sig line :blsmoke:
