I've got 5 babies growing well under a small florescent right now, when should I move them under my 400W metal halide to veg? Is there a certain week or size?

The powder? I've used it, it works well as long as you use a little less than it recommends, my grow wasn't under cfls though.

Your grow looks fine, put the lights closer so the seedlings don't stretch though

I've also been thinking about this lately, but don't have any real good ideas how to make it totally stealth looking with 2 ports and an ac unit. Maybe put the ac unit in the window, then on either side have a hole for the intake and exhaust. Then maybe dryer vent covers to make it look...

i've heard they pull better than push, but i have no evidence to back that up. its just the way i've always hooked it up

Those cups need to be closer to the lights, and the lights need to be cfls. they're pretty cheap so go pick some up at lowe's, some more fixtures, and some y splitters

right, or you can get a cooled reflector that won't necessarily have glass around the bulb but it'll still be air tight and have two ends for ducting

i think these fans pull air better than they push air so you might run into some trouble with this setup

Just get a filter and hook it up filter-cool tube-fan and exhaust it into the attic and you'll be fine. I like to over do fans so I'd be looking for at least 250cfm to get through the filter and pull the hot air out

So I've been working on this little metal cabinet I picked up cheap. Its deminsions are about 30''w, 35''t, and a depth of about 32''. I have a cool tubed 400 watt MH in there connected to a 225 cfm blower with a carbon filter on the end. I also have two large pc fans (120mm) blowing fresh...

no, you'll be fine with the heat from one 400 watt, its when you get into the thousands of watts you need to worry.

yeah i was going digital no matter on the wattage, so 400 over 250?

i have a metal lockable filing cabinet with dimensions of 30''h 32''W and 22'' deep. I'm planning on using it for a veg cab. Would a 250 watt metal halide light be good in a cool tube with about 300cfm outtake fan? I think this should keep it cool enough right? then i'm think about drilling...

i'm working on 1 right no with 7 cfls in it. with 2 fans and no holes cut it got up to 155F but i'm working on a new ventilation system, i'll let you know the results. But I don't think you'll be able to do a 400W MH without some serious fans

did you build that? where did you find such a perfect cabinet?

thanks for the info on that, I wasn't aware that the metal ones were actually that tough to cut through...

Yeah I'll probably hit up garage sales, because I don't want something cheap. I want it to be real sturdy, be able to look pretty much stock, and lock

I just completed my first grow, an attic grow with 1 plant. Turned out great and dank, and I have 4 more plants flowering now. However, I live in an old, rickety house and the attic just isn't doing it for me anymore. Its too dangerous eventhough I tried to make it right. Next semester I'll...

yeah you do man, if you had time to grow it all i'm sure you can find the time to open the jar and smell it once a day

well how long has it been curing in the jars for? everything i've read says it'll take at least 2 weeks for it to taste decent
