Cannabis Grow Rooms

ok. my room is set up. i will be using a closet about 2.5' x 4' x 8'. would this mean the sq. ft would be 10? anyways, i wil be growing with fluros aiming for stealth but i know this will cause heat probs. i have 4 shoplites running about 300 true watts. i have small fan i the closet pointed down toward the shoplites. i would love to run them 24/0 because im looking for a high yield cosidering they arent powerful lighting. ok problems : one of my ballast is HOT , i may replace it.. as it isnt a lights of america shoplite (which i find stay cooler). i have 3 daylight tubes 2 cool white tubes 2 shoplite grolux (soft white) 1 warm kitchen tube 1 soft white CFL 13 …

Helllos everyone, this is my first setup.. and i was looking to buy a 400w HPS. so when i went to my localstore i grabd a 400w package. it came with HPS400w son-t, jb 400w mh ballast and a reflector. but.. its not working.. i think the dude accidently gave me the wrong ballast.. as it said for MH.. or is it alright and im suppose to wait for it to warmup or somthing..

Went to the hydro shop today to buy a Fan and I'm concerened that the fan he's selling me is gonna be to small. Originally (3 weeks ago) he recommended a 250mm Axial fan. Today I told him that eventually I'd need a carbon filter and asked him if I'd be better of with a Centrifugal fan. He recomended a 150mm fan, which is some what smaller. I'm worried I'm going to end up with tempreture problems. The growroom is 3m x 1.5m x 1.8m = 8 m/3 or 10' x 5' x 6'= 300 ft/3 I have 3 600 watt HPS lights Current outside temps are 25C during the day and as low as 15 during the night

G'day folks! have got an air cooled 1000W hps and have been using this in a 4ft x4ft x9ft frame last few grows and getting good enough results. a few things have changed for me recently though so im rebuilding and now i have more space which got me thinking bout grow room size and my lights efficiency. would i get a better yield and maintain qaulity by having a larger room with bigger/more plants but obviously less light concentration or am i doing better by sticking to the at least 50watts/sqft rule ( 62 watts/sqft for my case). is the high watts/sqft helping me get bigger, more solid buds or will they be similar with the light spread out a bit more. I fully unde…

hey fellahs , my seed has sprouted and has 4 leaves wewt!!! i went to woolies and picked up a 23watt light but it puts out > 125watts phillips tornado one of those swirly ones http://img81.imageshack.us/img81/5700/picture264hj.jpg will it work? i dont want a beast plant just a small one , weekend smoker here (Y) (Y)

About to purchase a fan soon. Was gonna buy a 250mm axial fan (AllVent $220), but I will eventually need a carbon filter. Should I get a centrifugal?. Noise is a concern. My grow shed is right up against neighbours fence. Money is a concern, but if a axial isn't going to do the job I'm only wasting my money buying it. Can I get away with a axial? Area= 10'x5'x6' or 3mx1.5mx1.8m Could I get a Centrifugal and house it in a MDF box insulated with foam to reduce noise?

I've got problems with my plants not growing. It could be from light leakage during the dark period. I've switched from 24/0 to 18/6, is it safe to chenge back to 24/0?. That way I havn't got to worry about light leakage (for now). Also the plants are only 3-4" high. The lowest leaves are turning yellow from what I think is a lack of light. Is it safe to take the fluro's out and wack a 600 watt HPS in there?. What distance should I keep the 600 from the plants. I'm thinking 1 metre?. I don't think temps will be to much of a problem as its below 20c outside most of the time, and there is plenty of ventilation. They may not be growing due to cold temps too?.

Apologise if I'm doubling up here but Aldi sell digital timers for $9.95..(not all their stores carry them)

hi all i have a few questions regarding carbon filters i was hoping someone could clear up for me 1. i notice they come in different lengths. eg 250mm diameter is available in 500mm, 800mm, 1000mm length. what is the difference between a longer vs shorter filter? (besides price difference) . would a shorter filter be less efficient or be more restrictive on the air flow? should one always go for the longest filter they can afford/use? 2. what length filter would you recommend in (for example) a 4 x 1000 watts HPS g-room with a 250mm centrifugal fan (500watt fan - very powerful). 3. where should the filter be mounted? before or after the fan? (i have been …
