90 degrees and rising HELP! 3600 watt grow room!

I have a pretty nice 3600watt grow room with a 1500m3\h extraction AIR fan with a carbon filter and a 25cm (10") in diameter air hose extracting the air out of the room.

I also have a passive air intake wich is a a 25cm (10") in diameter air hose for the AIR in to the room.

I have 6x600watt HPS lamps with reflectors.

There is only 60 degrees outside but the room temperature goes far beyond 90 degrees in my grow room with the lights on!

The 1500m3\h extraction fan should be able do change the 60m3 room within 1-2 minutes!!!!

Why does the room get so hot? Have I done anything wrong?

Should I get a AIR in fan? 1200m3\h AIR in fan maby?

Or do you think a A\C (aircondition) is needed? I would like to pump loads of air through my room, and thought 1500m3\h extraction would be more than enough for my not so big room!

Im not familar w/ m3/h, I know what it means. You may think about cooling your lights before you a/c it.

switch the cycle to have the lights on in the evening, and off during the day, when the temp outside is warmer..... gotta get some fresh air from outside in the room somehow, if it's in the 60's... would really benefit the plants alot..

And how am I supposed to cool the lights?

The lights are on during the night, its pretty cold outside, but I have no chance to get the room under 90 degrees!! It`s climbing to over 100 degrees now.. Dont know what to do here!

bro your scientific calculations are scaring everyone away haha... post a picture of the lights and how their ducted and im sure someone can point out any errors

Yeah, if fresh air is at 60 and you are venting out the hot air, you should be fine so something must be wrong. Give us some pics please!

pics coming now. Room looking like a pig now, I will post new pictures for you when it`s done. But first we have to fix this heat problem!!!

By my calculations, 1500 cubic meters/hr = 53000 cubic ft/hr, which seems awfully high but if that's really what your fan is pulling then, you're right, that should be more than adequate for a 60 cubic meter (2120 cubic feet) room, so this situation is kinda confusing to me. Are you sure that your fan is really pulling 1500 m3/h or close to it? Especially with the carbon scrubber attached? And, where's the intake located? I couldn't see it in the pics.

First of all, where is your hot air from the carbon filter being exhausted too? Into the attic? Also, you should get some air cooled reflecting hoods or cool tubes or something to immediately suck away the hot air produced from the lamps. You also stated you have passive intake. Maybe you need to switch that into an active air intake.

Hehehe dude, you have done your mathematics wrong. If you want to change M into ft (meeters to feet) then multiply meeter by 3,28 and you get feet.

So: 1500m3\h is the same as 4920ft3\h.

My room is 60m3, or in feet: 200ft3

For the non-schooled ones here; m3 is the same as cubic! Cubic is the total room volume. Length X with X height = cubic (m3).

Right now I am not using any aircooled HPS, only top quality reflectors! I dont understand why the grow shop didnt sell me the air cooled reflectors when I spent almost 10.000$ on this room!!

Does everyone use air cooled HPS when they have more than 1 lamp? I have seen many videos on youtube where they use reflectors only.. Didnt think I really needed the aircooled ones.

u may have to invest in sealed reflecters so u can exaust the heat from the bulbs,with their own fan and ducting. Or enclose the ones
u have already since six more would b expensive.If he knew u were tying them together he should have given u air cooled. can u get rid of the charcoal filter for now?

lol 8 posts and 3600 watts. seems like a noobie went a bit over his head.

Your only fix will be to either lower the ammount of lights you have (6 for a noob is plain stupid in my opinion) or more fans. lots more fans lol.

The reason why your hydro shop didnt add more is because you are a dummy and they already just raped the shit outta you.

Quick fix: AC Units. Multple.
Quicker fix: Get rid of all your lights but 2. Even running 2 600w for a noob might be a challenge
Real fix: be realistic about your room build.

Gonna try a 1200m3\h AIR IN fan first, see if that helps:) A lot less work, and a lower cost! Personell in the grow shop wanted me to get an even bigger OUT air fan, even dough the one I have now should be able to suck out all the air in the room within 1 minute and 20 seconds! LOL

Getting rid of the ligts is NOT a good plan:) And how will a lot more fans help me? You do understand that a regular fan simply makes the air circulate, not cooling it or extracting it out for new cooler air to get in?

The way I see it, I have 4 options and will do it step by step untill I get it right!
1. Installing a 1200m3\h in air fan
2. Adding 2x 1200BTU A\C. Does anyone know how often I will have to empty the 2,5L water resorvoir on these?
3. Installing a 1500m3h IN AIR fan and a 2500m3h OUT air fan. (would be LOL)
4. Installing aircooled HPS lamps with their seperate ductings and out air fan

What are temps in the room your pulling from? I think you just need to pull from outside versus the room next door. Air conditioners are always nice though.

1 cubic meter = 35.3146667 cubic foot 1200m3\h = 700cfm for us Americans.

Maybe that's why it seemed awfully high to me. I was using this calculator, which claims that 1 cubic meter = 35.3146667 cubic feet. That's where I came up with 60 m3 = 2120 ft3 (= 60 x 35.3146667).
