    Grow Room A/C

    Dear CJ, I'm setting up a sealed environment, will be using a 8kw (27k btu) mitsubishi split, was wondering if I ran 8x 600w lights on a flip flop only 4 on at a time, being at 65-70% of capacity of the split how long would the unit last running 24/7? And how often would it cycle on and off...

    Grow Room A/C

    Thanks for your quick reply John, Ok, would i be able to cool each row with 7 fans, and then duct all the 8" fans into a large 20" duct running down the side of my room to the outside? I would love to run two very large ducts down both sides of my room so i can intake & exhaust all the hoods...

    21k Tabled Scrog Setup Design. Opinions on cooling/air cooled hoods.

    So you reckon doing the air cooled hoods in 7 vertical groups of 6" fans? I was gonna use 8" ones incase i change the setup later on etc. It'd be 3 in a row each then. I will have constant cool air coming into the room yes, and the room will be incredibly well insulated & the room itself is...

    21k Tabled Scrog Setup Design. Opinions on cooling/air cooled hoods.

    Hi guys, it's been a while since i've posted up on the farm. I'm venturing into new territory with 21 x magnum xxl 8"s. I've never had air cooled hoods before, i've had setups the same size as my new project, but normally i split them up into 2-3 smaller rooms to make cooling alot easier. This...

    600w or 1000w layout schematics, advice :)?

    Ahhh that makes sense...having it on the floor wouldn't really help much at all would it? but if it's level with the top of the pot, that reflectivity would be x2 or x3 better! You certainly know your shit, thanks again for the tips man, few things you've said will definately help me achieve...

    600w or 1000w layout schematics, advice :)?

    Yes i actually use a silica rock and coco mix at 25/75, the silica rock breaks down over the course of the grow and allows the plant extra uptake of silica, i always have the bottom 2 inches of the pot as hydroton for drainage help. I have painted melamine white walls & ceiling for...

    600w or 1000w layout schematics, advice :)?

    thanks for your very informative reply dank, just some quick maths. i have a 7.3' ceiling. i'm doing coco dtw, my pots are 1.6' high, say the reflector & chain is atleast 1', needing to be atleast 1.5' away from the top of the canopy at all times. this leaves about 3 feet of plant space. 1st...

    600w or 1000w layout schematics, advice :)?

    I have a 12' x 16' space, with a 2' walkway down the side of the room (whole open room is 14'x16'). Just wondering if you experienced growers would use 12 1k lights to cover equal 4x4 portions of the 12' x 16' space ( 3 across and 4 down ). Or would you lean towards more total light coverage...

    Need some life advice on growing...

    Thanks for the advice guys, I really wanna do it by myself, the only thing making me even think about his offer is the initial setup costs and mortgage payments, it is doable but I'll be eating tinned food for 3 months lol. If I could work out a shorter deal with the guy like only 2 or so...

    Need some life advice on growing...

    Skunk x Afghan Coco, go hard or go home?

    Yes i've run under-lights on all of my grows nearly. If i merely had the 12 600s on top, i might hit 6~8lbs of nice big heads, but the lights underneath add a minimum of 3~5lbs of big heads aswell! It's theoretically the same as vertical supplimental lighting but a bit of a room saver to really...

    Skunk x Afghan Coco, go hard or go home?

    TriFan; Normally i'd shave the legs on girls if i didn't have so much underside lighting, i actually get buds as big as the top ones on the bottom legs, so i try not to shave them too much lol. TortureKill; I'm pretty sure it's a Super Skunk x SAGE, atleast this is what my good friends tells...

    Skunk x Afghan Coco, go hard or go home?

    Yea, it's sort of an all-out cash crop method of growing, just 6 really massive plants spread over 14-15m2, lights everywhere lol! And yea the boys are my life! Theyre just over 1yo now, and should grow into real monsters like their dad ;).

    Hello, closet garden on it's own...

    Few questions before i offer my advice to your situation... What type of lighting? Does it put off much heat? What type of medium are the girls in? Is there good amount of air flow or little or no air exchange happening?
