1000 watt HPS
    #459799 - 08/14/10 04:44 AM (6 years, 3 months ago)

Hello, I'm officially a medical marijuana patient August 25th!

I'm getting some extra supplies together to start up my 2nd grow. My first one went pretty well, but there are some adjustments I'd like to make.

First, I am allowed to grow 12 plants. I want to use a 1000w HPS for this because I believe that will produce the best results. Can the heat from a 1000w HPS (remote ballast) be controlled in a closet environment? My first grow was in a closet with a 600w HPS. We had a cooling tube going through the hood and a nice intake/exhuast system. The smell NEVER built up and the temperature was controlled. I need to know if a 1000w HPS will be able to be controlled in the same environment.

Here is the light I'd like to purchase: http://cgi.ebay.com/1000W-HPS-MH-DIGITAL-GROW-LIGHT-AIR-COOL-HOOD-1000-WATT-/300452714345?pt=LH_DefaultDomain_0

Thoughts?

Also, how far away can the 1000w HPS be from the plants? I need to know for seedlings, vegetative, and flowering phases. I plan to use a metal halide bulb in the light for the veg phase.

The closet I have to use this time has a shelf that cannot be removed about 5 and a half feet from the ground. I figure the 3 gallon pots will be about a foot of space, and the light obviously must be fixed just under this shelf, so I have about 4'-4'6" ft of space left in between. Will this be enough, or will my plants roast under a 1000w HPS?


Here's what the closet I'm dealing with looks like. The picture on the left is a representation as if you were looking at it in front of you, the line represents the shelf that is inconveniently in the way. The picture on the right is a birds-eye view of the setup I'm shooting for. Now another question arises, will a 1000w be able to cover that arrangement properly? I ask due to the width of the closet and lack of depth. If not, would 2 400w HPS lights be more suitable, one on each side (I lose 200w this way, and have to pay more for each light). And if I had 2 HPS lights lined up, would the heat be absolutely out of control? I feel safer with just 1.



Edit: I am also seriously considering setting up a ScrOG. I am interested in the technique and I think it wold be better utilization of the short height I am given. I think a foot in between the soil and the screen, and the colas that poke through the screen should be about 8-10". That would give me more room in between the tips and the bottom of the HPS. Can a low ScrOG be set up from seeded plants  (feminized)? Or is there too much of an initial stretch from seed plants, and will clones be needed to properly set up a ScrOG?

To address one of your questions (which I think is the most pertinent), the 1000w won't adequately cover that length of room.  The two 400's is the way you want to go with that space.  Yes, you lose 200w, but if you just use the 1000 you'll lose a lot more than that on the plants that don't have a good light source.

Welcome.
And congrats on the license tho im sorry you need it.
12 plants is great. with a six month veg time you can easily get 6 ounces from one plant so 12 with even half that time would be amazing
with enough ventilation 1000 watt could work i didnt click on your link but there are some pretty badass lights out there.
I know you said you can remove the shelf, but, what about cutting a hole out for the light with a jigsaw, imo that would be the way to go.
thats a long closet. you would be better off with two 600's then one 1000
scrogs and LST in general is great to maximize your canopy and lumen intake.
also remember that you have to water those plants. if your pots are flush to the ground your gonna have water on your floor. you need something underneath that will collect runoff, this might raise your plants even higher to the light.

with all that said. im still on my first grow. most of what i have said is just regurgitation

Damn. I figured that would be the case about the lighting system. The only problem is that I can barely afford food right now, I'm not stupid and I know growing is expensive, and  I like to do it right so I'm putting 100% of my funds into this. I think 2 400ws wont be enough for 12 plants, I won't be getting as much as I can, nearly. 2 600ws would be fucking great, but I seriously don't think I can afford 2 HPS lights, let alone control the heat from 2. I feel due to the lack of depth, the heat buildup is gonna be pretty bad.

No way I can scrape by with 1000w's in that environment? Mind you the room will be fully covered in mylar.

No way, unless that room is less than 4'6" long you're not gonna get coverage.
2 400's would be adequate, it comes up just shy of the recommended 50w/ft^2, but your coverage would be WAY better, and your yields would be significantly better than with the 1000 in that space.
I highly recommend craigslist for grow supplies...can usually find cheap ones.

Yeah I just did some searching. I can score 2 400w HPS Cool tubes for around $400-$450, so thats only $50-$100 more than the 1000w.
