400 watt HPS in THIS size room?

Hey guys,

Back again for a second grow and I've managed to get my hands on a free 400w HPS and ballast. The problem is, I'm really not sure whether I will be able to hook it up and grow without burning my damn cabinet and/or house down.

The dimensions are; 50" high, 18" wide, and 20" deep. To get a better idea of my set up last time, check out the thread in my signature and it will direct you to my last grow.

I've decided to go for two auto-flowering Red Dwarfs, maybe three but I seriously doubt I have the room. Any advice is welcomed!

I would say just fine-tune your CFL growing with another one. If you can vent the tube you could probably scrog it and do fine. Can you drill 6" holes in the left and right side of the grow area and have access to it?

Well I really wonna do these red dwarfs, and from what I've read, they aren't the best to scrog with, if at all. I cant really be bothered with the hassle of the scrog method again either. I'm looking to just get a decent 2 oz or so off of small but compact as shit plants.

As for the drilling, not really. The cabinet is fastened to the back and right wall, meaning it is in a corner of sorts. I can only acess the left and front sides.

Are these any good? Click me

I haven't researched much in the way of CFLs but if you're looking for a quick 2oz I would say just stick with them. I always go to a home improvement store for bulbs first and see what they have my problem is finding the mogul bases out here. Why don't you just use the same set-up as your last grow?

Yeah well I've already got a 60w HPS. Its just I only pulled 18 grams off that last grow and I was using the HPS and three CFL's at 20-30w each. In total I had like 130 watts if I remember rightly. Its just a pain in the ass positioning them right as I can't really do any drilling so it all comes down to shaddy D.I.Y work haha. I'm just thinking 130 isn't gonna be enough for two autoflowers...

Yeah that's like .13 grams/watt have you thought about trying something like the setup in this post? https://www.rollitup.org/cfl-growing/57813-advantage-v-disadvantage-cfls.html

I think if I was going to put some money into a cfl grow I would do something like that.

Yeah actually after our little chat here I've set up another little gig in the cabinet. This one looks much better than the last, I'll see if I can put some pics up soon. I've got four CFL's, two 30s and two 20s, and then HPS at 60 watt in there. I may well give that method a shot though if I can gather enough money together.

Yeah, I'm not very confident with wiring things but if you can get around that and the cost of the initial set-up it looks pretty cool, and it can pump out 600+ watts if you get 42 watters.
