Sorry couldn't find my book, but I did manage to find some info online. 1 watt = 3.413 BTU/Hr therefore: 250 watt lamp =853.25 BTU/Hr 400 watt lamp = 1,365.2 BTU/Hr 600 watt lamp = 2,047.8 BTU/Hr 1000 watt lamp = 3,413 BTU/Hr Theory behind it: Watts = Voltage x Current 1 Watt = 3.413 BTU/Hr...

Im running a delonghi 12k btu portable ac and it has ZERO trouble in keeping my 600w grow cab and surrounding area cool. I have the AC positioned right next to, facing my grow cab, and the exhaust pulling air off the lamp on the opposite side into the same room. Only problem I had was the AC's...

Im also wondering about this same a/c smell problem. I think that 50% of the air in the room is recirculated back into it, but the other 50% is used to exchange heat and then pushed out the exhaust which would cause it to be un-scrubbed. maybe theres a way to get some carbon in front of it...

Also make sure you know your environment in which you plan to grow. You should pick up a handy temperature and relative humidity gauge. I have a nice digital one that was only around $20. Take note to how hot it gets naturally.... you don't want to get to deep into building your cab just to...

what are the dimensions of your cab? It sounds like it should be small enough to run a passive intake (no fan, just a "hole") and use 1 single fan to suck air out of the grow room and through the carbon filter. As long as there is an intake hole with fresh air coming in, and the exhaust fan...

I was wondering how portable a/c units work. Do they suck air out of the room? If I have it set up in my grow room, will it be pulling odor filled air out its exhaust hose and out the window The unit has 2 separate intake vents. 1 on the right side, and one on the back. I am thinking one sucks...

awesome thanks for the inputs guys :)

thanks hyroot! Im going to look into the blue and red spectrums a little bit more, what your saying seems to make sense, and also goes along with the common knowledge of vegging with MH (blue) and flowering with HPS (red). If I do see stretching with my LED's what are some practices for...

Ive heard from a few different people that plants grown under LED's tend to stretch more and during flowering buds are less dense. Is there any truth to this or is it just a rumor? If true, what are some measures you to take so this does not happen?

awesome thanks beef! I really like the reviews I've read and gotten one the pro-grow, seems like mostly happy customers and happy trees :) ... What do you think about running a 400w HPS with those 2 pro grow 180's? Im having heat problems in my grow area during the mid day, however I was...

Hey, I would like to use an LED system in my scrog grow cab of 2' x 4'. any suggestions for which light may cover this the best? would one pro grow 260 be a good idea? or should I consider 2 smaller sized units? Thanks for the input

Hey Profgrow, awesome thread! lots of great info here! However I did have a question :) I know its a little bit of an issue between growers when talking about cutting off lower growth, (some say its fine, some swear against it). If the issue is just cutting off nutrients that are stored in the...

gangaguru, Welcome to the forum :) For lots of info you can use the search bar and normally find lots of answers. There is a good sticky on proper ventilation techniques, and really good info that may help you with your problem. OTHERWISE..... What is the temperature of the outside air being...

Thanks fireproof that was exactly what I was looking for! I ended up covering everything with insulation, and now the ducting went from being very hot (almost too hot to touch) to not even a few degrees of temperature change. the 4" insulation was $25 for 25 feet. I only needed about 6ft for the...
