    Hidden attic space 4x4 cooling advise.

    You could make your cool tube a closed loop cooling system, then have the rest of box be sealed tight. Intake from your house and exhaust right into your attic ( assuming you have vents in roof/ gable. The majority of the heat from the bulb will never get the chance to heat your box up. With a...

    250 Watt Hps Light

    Ok so speaking from my personal experience, the smell WILL become a problem. My first grow was very similar to yours, I had 3 plants under a 250 halide and a 150hps in a 2x3 space. I thought that the smell wouldn't be an issue cause I smoke all the time anyways. Well ya, live growing plants in...

    I NEED HELP, grow cab issues (PICS)

    Think efficiency. Any where you can get rid of equipment and maintain your environment. For example flip that filter so that it pushes down into the hood, removing some ducting and the bends with it. Get rid of the intake fan and increase the inlet hole size a bit. Also take some time and seal...

    Question about 8x8x4 grow box lighting? (CFL Question)

    Ok gonna do my best to get your questions answered. Starting with the light spectrum of bulbs. This is by no means a end all statement but some solid info that will get the point across. Think of the ####k of a bulb as kind of a numerical value for its color it peaks at. Far...

    GrowBoxTempRegulation

    I got it! A ceramic heat bulb for reptiles no light and you can get em in like 50w- 75w sizes. Probabaly the smallest one you can find will be perfect.

    Green Grow Room

    What you need is deep cycle batteries ($80-$180 each), im guessing to start with at least 3 but it will depend on the specific batteries used and total watts needed. I might also suggest a solar panel as well, I've seen them for RVs under $100 it wouldn't keep them charged by itself but would...

    GrowBoxTempRegulation

    How big is your box? You can get a heater for $40 and a t-stat for $20 and your low temp will never move. I personally don't like the green light idea just cause it goes against my no light at night brainwashing. If you do want to use the light then stay away from coated bulbs cause under that...

    Is this Negative Pressure Overkill??

    I use a 6" 239cfm fan to cool a 400w cmh and a 250w hps in the same hood. I use a cheap 4" duct booster fan for intake. My room is roughly 3'x3'x4' and temps stay at 78 with a intake temp of 68. So yes I think a 230cfm fan will be just fine assuming your intake is of adequate size.

    Heat Buildup

    Im curious if you were to open you garage door a bit(the big one) and cracked a window in the room with your closet will your temps come down? If you have a newer house its likely its sealed so well your simply not getting enough air to move to start with. If its an older house then most likely...

    Heat Buildup

    Ok first off this is my thoughts on radiant heat on plants(again just my thoughts), if your temps are still in a acceptable range in direct light and lower in the shade then I would not worry as long as plants dont show stress. but if temps are out of range say 100+ then I would dial down the...

    Heat Buildup

    I wonder if the radiant heat from the bulb is to much for that small area. You can't cool radiant heat with airflow. You might try to shade your t-stat and see if your air temp is actually less then your reading. If it is maybe just dial down that 600. Im probably just stoned and not making...

    Question about my 400 WATT HPS,Turned off by itself and then turned back on

    To me it seems very strange that the wires are all new but its in a old case makes me wonder.... but anyways the fact that the first sign of trouble was when you bumped the tiwould start there. Make sure all connectios are fully seated and well connected, is timer a inexpensive type? if so might...

    Dark room 40 125 cfl major heat issues

    It dosent matter how much you move that air around if it doesn't have anyplace to go. You need a intake and exhaust, 4" will work fine and you can get small duct booster fan for like $25 at home depot. Excluding carbon filter you can find everything you need for a effecient cooling system for...

    First grow ventilation question :) thanks for any help :D

    I think you need to bite the bullet and buy a a/c reflector, you can still use you carbon filter and with the reflector you will be able to move more heat with less airflow. Basically the amount of cfms you need is dependent on how effecient your cooling setup is. To cool this space I would...

    Question about 8x8x4 grow box lighting? (CFL Question)

    Hey tiny, this setup looks great. I want to answer a few of your questions 1. Your new 68 watt cfl bulb is a 2700k bulb which is perfect for flower. 2. Daylight bulbs do work great for veg and cloning (6500k) and so use those bulbs in mother/ veg/ clone chambers. Try something like two 26 watt...
