hps all the way, there is no comparison between the two, only use cfl's if you have severe height limitations, and by the way watt for watt cfl's put out more heat than an hps, its just that its spread out over a larger area thats why you can put the bulbs closer to the plants, this seems to be...

yeah go with the 600, im running 2 600's in a dr 150 tent which is almost 5x5 with air cooled hoods, i cool them with a 100 cfm 4 inch fan for the hoods and then i have a 150 cfm with a carbon filter just for exhaust for the tent, the fan i have hooked to the lights also has a filter on it and...

it breaks down like this, a 1000 hps is 140,000 lumens, a 400 is around 50,000 so it would take 3-400's to equal the 1000, now the 600's put down 90,000 and some bulbs are 95,000 so clearly watt for watt they are the lamp of choice, so with 2-600's your putting down 180,000-190,000 lumens, thats...

i would rotate them around the room every few days if you want to get equal size, otherwise they look good when a plant is flowering it is in the end of its life cycle and basicly.....it is dying, when they are almost done flowering they will be all yellow and not looking so hot...except for the...

im 6/6 with attitude now

i just got a sweet t-shirt that says DUTCH PASSION ....and some kandykush beans to

ice turns purple at the end if you let it go an extra week, by time that one finishes it looks naaaaaasty, im looking for some grape ape

no its quite the opposite, indoors an indica will out yield a sativa of the same size almost every time, now outdoors a monster sativa will have the advantage, but if your growing indoors and yield is of concern go with an indica

pick the males as soon as they show the little balls, dont pick them until the hairs on the buds are turning brown, your almost there so dont pick to soon

if you really need to do some early chopping take a few small buds off the bottom of the plant and leave the colas alone, once they are farther along in flowering the trichomes will be thick and it will look like it got dipped in sugar, when you pick it early the thc is not formed completly and...

if you want a quiet fan go with fantech, pretty much the more cfm the louder it is, most of the fan noise is not from the motor its from the moving air and the blades cutting the air, im not to familiar with that fan but it looks like an industrial fan that moves a shit load of air, i would...

no no no no leave them, those are the bud leaves those will make some exelent bud shake and they will be all sugary in no time, plus they give the buds power to grow

those work best on a light mover, if you leave it stationary all your light will be in one spot,so a 2x4 tray ? i would look in to a reflector that puts down a wide footprint instead of adding a light, the hydrofarm daystar is pretty good at that

you can run a cord for miles if you want, you just have to make sure its of proper gauge and up to the task, the only problem with cords is when you try and pull to large of a load through a small cord, i mean think, from the power plant to your house is pretty much just one huge power cord

that was a northern lights#5 x haze in my pic

what happens is the 400 watt bulb trys to pull 400 watts from your 250 ballast causing the thing to overheat, never mind the fact that your using the wrong bulb, if money is the issue go to home depot and get one of those regular mh bulbs for like $15, it will work good

a 430 son agro is about the best small bulb out there in my opinion, its got the output of a hps with a enhanced blue spec, thats what i use for veg, you see plants use much more red light than blue so if you compare a plants color response against the light of a halide you will see that it only...

what i would do is use the big fan to cool the lights, just run the pipe so the air cooled lights supply of air has nothing to do with the tent, it willl just run strait through from the outside of the tent through the light and out that way you can put the other exhaust fan on a temp control...

cops were in my grow 2 weeks ago and left empty handed, thank you prop 215

i let it get no hotter than 90, even though you can go higher with co2 i still prefer temps in the low to mid 80's with co2, i read about going up to high 90's with co2 but i dont think its worth it really, i have best results when i keep the temps where i usually would
