Just bought a 1000 watt hps and an 8 plant aeroponic setup...

What type of yeild should I expect in a small 2x3 ft. closet?

The 'holy grail' is 1 gram/watt, so 2.2 pounds if absolutely everything goes perfectly. Of course, there's a lot more to it than just your lighting, but that's probably the single biggest factor affecting yield. Not many achieve that though, and certainly not in their first few grows. Realistically, hope for half of that and if you get it, be happy, and consider anything beyond that a bonus; it's better to be a pessimist and pleasantly surprised than an optimist and completely disappointed. ;)

That's a pretty small space for a 1k light, btw, and really more suitable for a 400w light. Hope you have all your ventilation needs figured out and taken care of!

no shit 6 square feet and a 1000 watter.wow!!!!what is that about 120ish a foot...god damn!better have ac in there:D

I was planning on running a carbon filter with an exhaust fan on it with a small hole on the bottom cab. maybe a couple clip on fANS inside to keep it cool?

If I were you, I'd definitely use a cooltube on your light. That'll help keep your temps under control. Clip-on fans moving the air around inside is also a good idea, to strengthen stems and circulate air. That's about 3 times as much light as you need for that space. I don't think it'll do any harm to the plants (although it will harm your electric bill!), but you'll have to design everything around that light and the accompanying heat that it will generate in that small of a space.

To put things into perspective, my cabinet has about the same area in terms of square feet (it's 20" deep, but 47" wide, so not as deep, but wider). Here's a few pics of the cabinet with just three plants in it, and using just a 400w bulb with some accent CFLs (four 30-watt warm CFLs on each side), for a total of 640 watts. My temps inside the cabinet run about 10 degrees hotter than ambient room temperature (if it's 70 degrees in the room, it's 80 degrees in the box), if I have all lights running.

I would have probs running a 1k light, personally; I don't know if I could keep it cool enough. But besides that, even if I could, I don't think I could really squeeze any more plant matter into the space, regardless of light, so it wouldn't make sense for me to use more light, because that'd just raise the electric bill. Heh.

If you do get a 1k light working in that small of a space, and handle the heat okay, show us some pics! It'll be pretty impressive if you can do it. I know people *have* done it successfully.

I'm really impressed bro,shit thats a nice set up.I'm thinking bout usin the "cool tube" and you just sold it.How many grams do you average per yield jam?Do you use a fan around the plants or does the cool tube do it?Just I can't see one and those stems look strong.The branching is beutiful too.

Well done Jam 10/10 in my book.:thumbsup:

JAM "pot plants" lable is killing me

Haha, yeah, I thought that was funny when I added it too. ;)

Average around a pound, sometimes a bit less, sometimes a bit more. That's just buds, and there's usually a few ounces of leaf too. The woman likes joints (and I don't), so I twist her up the leaf stuff, we smoke the buds together, and if I smoke alone, it's bud. Gonna try some cooking before too long too; just got a crockpot specifically for that (woman was paranoid of me using the good crockpot and making it permanently smell of pot).

You won't regret using a cooltube. Very space-efficient, and great at keeping the temps down. I do have a 6" oscillating clipon fan blowing on the plants. You can't see it because it's kinda tucked behind the cooltube. There's another one blowing on the ballast, although it's a digital ballast and probably doesn't need it, as it doesn't get that hot. Normal non-digital ballasts get quite hot though, so if that's what you have, I'd keep it out of the growing space.

A 1000k light in that area, whoo, woo. You better be up here in Alaska. You are going to be able to bake bread in that bad boy. Seriosly, temps are going to be your arch enamy. Before putting any plants in there you will want to do a test run without any babies in order to gage your temps.

Lmao "bake bread".The fist herb self tanning light lol!

Thanks Jam,that'l be great help.I have a 400w hps with built in timer.Changing to 600w for this grow.I usually start them with 200 enviorlight blue.Gives them a good start and the temp is nearly never a problem.I'l keep an eye on the 600w I know its gona make a big difference.Should be ok.

well its actually going to be in A cab sorta like pictured above. I already bought the lamp, hydro unit, and carbon scrub so I am going to use the stuff. The ballast will be outside the cab and there will be 2 fans ( one on the light, one on the plants), as well as an exhaust fan on the carbon scrub so air will be moving.

Okay, I think I have the cooling figured out. I bought two 6 blade metal halide cooling fans. Each one has six 3 inch fans and pushes 46 cfm. They will be attatched on either side of the hood pointing at the lamp.

here's what they look like

Dude do you any idea how many fans you will need to cool your cab?? A
1000w is a monster and puts of way to much heat. I had one in a closet that was 5 feet long and 3 feet deep. The light was in a cool tube and i had direct AC in the closet. My temps were still very high and the closet door could never be shut. Not to mention my elcetric bill went up about $120 a month...to me it is not worth it....good luck tho

OK partner, I am just giving you a back up plan that you want to set a few chips aside to try to implement in the event that your plan fells and even with this it may not help. First of all if you have never used a 1K then you can not comprehend the heat you are dealing with, try 300 degrees plus, go and open your oven, put it on 300d and see if those fans pointed in the oven could expel the heat quick enough to leave a plant on the oven Dore for 12 hours and trying to keep it at under 85D . This is what it is kind of like using a 1K bulb.
Well to the plan, I have a 1K bulb in a area 47in by 38 in and keep my temps at about 80/81D with lights on with the MH and expect it to go up with the HPS a little. I have an air cooled hood with a vent on the very top and my 172 CFM Vortex fan sucking hot air out of the hood into my scrubber. On the intake vent on the side of the hood I have a 90 CFM Dayton fart fan pushing air in to the hood to help the Vortex. I have another 90 CFM fart fan acting as a active intake on the bottom left hand corner and a 280 Squirrel cage fan bring in cool air in from out side, temps get around 45/50D at night hear. The Squirrel cage fan may have more CFM than the vortex, but can't come close to the air the vortex actually moves. I also have a 10 in honey well fan in the cab for air circulation. With this set up I can lay that hood on my chest if I wanted to, LOL. Sometimes I just put my hand on the glass and wonder how long it will take to fill some discomfort. I could put that thing about 6 in from my plants, but I would loose some of the foot print and run the risk of bleaching the tops of my plants so I keep it at about 12 in from the tops of the taller plants.
I know pics, pics, pics. Well internet got kicked back to dial up until the 8th of Sep and I need to have my wife get a cord for the diggy kam.
I am really liking my set up so far and am hoping to share it with everybody soon. I know that I have got about 90% of my ideas from these boards and enjoy giving back. With my set up now, it would seem impossible to some, but with some persistence and a few extra bucks it has paid off. Oh, I can't forget a awesome super wife who is my soldier, comrade, best friend and lover for life.
Adieu

thanks for the good info. This thing is turning into a huge money pit... Iguess I will build a cool tube or buy one...

It's only a money pit until you get it working; after that it's just electric bills and consumeables. But yeah, I totally know how you feel. Initially, I thought I could get it all done for like $700 or $800 (I wish!), but it went beyond that, and kept going, until I thought I'd never be done spending money on it. It's worth it in the end though! ;)

Ha Ha, I thought the same, now I look at it like construction or remodeling you need to add up your estamated cost and then times it by 2 and 1/2 for a good idea of the real cost.
I think that one quote that I think about the most when building a cab is Zandors "Go cheap Grow cheap"
I do understand that we all don't have the bucks to spend but when your goal is to do mor than a QP every 2 months then you are going to have to put a few chips into the bucket.

Oh right I thik I have the cooling issues figured out... again haha. So I bought a cool tub and a 6in. 250 cfm inline fan. I am going to run hose on each end of the cool tube as an intake and exhaust to the outside of the cab. I also have those two $70 fish tank fans to facillitate in cooling the tube. The only thing I haven't bought is the cab and a couple of various other odds and ends. Here is the price list so far:
Aero Setup: $280
1000w hps: $250
Carbon scrubber w/ exhaust: $80
6 FAN BLADES X2: $140
250 cfm fan:$55
Cooltube: $100
Total: $905 and I still need to sped about $200

2 x 3? wow.....bout 4 plants will make it.....and u will crop like 1/4 to 1/2 lb.

im goin to be running a 1200cfm in my 3.5 x 5 x 8 room with a 1000w hps and 400w mh at the same time....i hope 1200cfm is good enough....lmfao

It'll be more hopefully. Its an 8 plant and I'm not growing feminized. So I doub't I'll be growing more than 4-5. I'm doing the scrog method also. For the first run I have some lowryder/northern lights cross seeds. I,m hoping for smaller plants with bigger buds.

Was just wondering what 6 fan blades are?

Also if you wouldn't mind telling mw where you get the fan for 55.

Cheers

the fan pictured above.
Ebay had the fan
