Been having some heat problems with the non vented 400MH while vegging.Switched to my 1000MH with a vented hood and ran a dedicated fan for that.Also I got a y tube for intake so 1 part of intake goes through carbon filter and the other from a/c.Much better.temps now around 81.The LA Confidential def seems to be the slowest grower.The Madman seem to be growing the fastest.....I got the Madman,La Con and Kushberry on the 20th and the 2 SFV and 1 Tahoe a week later.

imo your temps are still to high. my flower room got to around 80-82 for a couple of days and i noticed bud production slowed dramatically. i fixed temps and they picked up a week later. I look at it like i lost a week off schedule!!

Yeah the temps are higher than I would like for sure. My problem is the exhaust heat is being dumped back into same room. Window is open but I cannot vent straight out it because of neighbors. The 1000 in a 4 x 4 is hard to keep cool. Ac being sucked in helps a lot. At least when it is on. Prob 60 percent of time. I really want a real portable ac unit to regulate temps better. Expensive though. No can do air chiller either. Sigh

Is your 1000watt in a cool hood, or cool tube? You might also step up the fan to a 6 or 8 or 10 inch if possible(ultimately the cfm is the most important, not the size, but it is still an issue).


If you use a cooltube or cool hood, you can vent out the light heat, Issue. If your room has all the heat, you might try using an attic/ceiling exaust. This would simply puke all the hot air from the room, into the ceiling/attic. Wether or not this is possible, you need to do something. The tent will always be hotter inside than the room it is in. Also, a 1000w in a 4x4 is bordering on toooo much. Why, I have a good friend with a 4x8, and he has problems with getting rid of the 1000watts heat, with a cool hood, with an a/c in the tent, and with an air conditioned room our side of it! ! !

You might bite the bullet and scale down the 1000w for a single 600w, and supllement with the t5's. . . just a thought.

One idea, it would take a whole lot of rigging( duct tape and ducting). . . but you can always put a window a/c in a window, and duct it into the tent. For about 499$ you can get a 25,000btu at lowes(maybe home depot as well). I personally have the portable Soleus, but yes they are expensive, and hard to fit into a 4x4 tent.

Its a Hydro-farm Reflector with lens.It has built in 4" flanges/openings on both sides.I am on the same page with you regarding the 1000 being maybe too much and the need for a bigger fan for exhaust.Those are the two main things I constantly think about..My last few grows have been with a 400w but some was willing to loan me a 1000w.So I am giving it a go and am now thinking..hmmmmmCan this be toooo much light/HEAT Ideally I would have a 600w electronic with at least a 6" fan just for the light exhaust.Next year.....
Well I have only Two-4" fans.One pulls air from inside the tent thru the carbon filter and at the same time fresh air from outside connected by a Y connector(also a small 4" duct booster fan sucking from end of outside ducting)--thru the light--thru fan--then exhausting HOT air to ceiling in room towards cracked window.Fan 2 is pulling air from outside tent thru carbon filter and from ducting connected to ceiling central ac/vent(which used to be on all the time..now its cooling off outside..sigh) to help cool.
I really cant have anything showing from my window as it is a semi-used walkway by it.Also the a/c unit would be weird since there is central a/c in complex.I guess I should at least get a bigger fan to help suck all that air thru the light and filter.I can post some pics if it helps with the venting setup.

You can always buy some of those pancake inline fans/booster fans from home depot for around 25 to 35 dollars. 2 mor fans is two more fans( for in or out).
