86-88 Degrees too Hot?

[disoBAYish]

Is 86-88 Degrees too hot for 10-12 Sativa clones? With the light off it gets down to 75-77 Degrees in my 3 x 3 1/2 closet.

You're at the upper end but as long as you keep an eye on there water supply they will probably be ok. Done around 80 is perfect.
If these are sativa dominants they may not do real well in a closet, they may need more room. If you used co2 86-88 would be real good.

a good supply of fresh air can help offset high temperatures

My temps stay around 88 and as Dutchpimp said if you have a good air flow you should be good... What type of lighting are you using?

Happy growing:jointsmile:

I have a fresh air supply. Both cool air intake and hot air exhaust from two '6' inch blowers. It didn't fix the tempature issue. The problem is coming from using a 1000 watt light, converted into a 600 watter in a 3 x 3 1/2 closet space. There is plenty of fresh air, just way too much heat coming off of the light, even when I use a blower to cool it down it is still hot to the touch.

I know nothing about Co2. Maybe I should look into that.

I introduced 6 White Widow clones into my closet growroom today. It is running at about 82 Degrees right now with a humidity level of 45%. The light has only been on for a few hours, so tempetures could still easily rise. I'll keep everyone updated cause I might need some tips later on down the road.

Like add a passive vent to the room!:thumbsup:

Wait, are you running a 1000w light on a 600w ballast? A little clarification for the smoky mind, please?

Yes and no. Lol.

The light is a 1000w Sun System yes, but the ballast is interchangable. It has a dimmer on it that has 4 different lighting options. 1000w/750w/600w & Super Lumens.

I have a 1,000w Lumitek Ballast, The purple one..... From what I understand, you can use any of the lighting options from a 1,000w light because the ballast dims the light down to the desired wattage.

Your staring to scare me.... is this a no no?

BTW.... I have my temps down to 81-82 with the lights on now. I hope it stays around there and doesnt shoot back up.

Always match bulb with output. Underdriving a bulb, just like underdriving any electronic device (unless it is designed to handle such things,) can cause undue stress on the electronics, the bulb, and more.
