2 600 watts - 45 inch para reflectors 4x8 room

[medmaker420]

Here is the setup idea I currently have and would love people to let me know if this sounds feasible.

2 600 watt lights (lumatek generator readys)
2 http://www.hhydro.com/cgi-bin/hhydro/HH00623.html - they say 4ft so I might be cutting it close. I am just trying to picture the best way to disperse the light from the two 600s.

I am building a 2x4 framed and plywood cabinet/room (4 wide x 8 tall x 8 long) that can be put together using only bolts, so it can be broken down pretty fast as well as be sturdy.

I am thinking of doing a very cramped sog or scrog setup in this using the 12" 5 gallon pots and cram them all in there. Focus on either large single nugs OR cramming them under the screen until all undergrowth worth budding is ready.

My thought is to actually do 32 12" 5 gallon pots only using the 2 600's and wanted to get peoples thoughts on this as well as the 4' x 8' size as well. It just is the perfect size to not have to cut any plywood except for the door sections.

Is the 1200 total watts using those reflectors capable of dealing with the sqft? In my head it is pretty much 37.5 watts per sq ft and think that would be fine especially with the dispersment the reflectors (I assume) will bring.

Am I too large on the room for these lights, better to bump up to 2 1ks in there? For some reason I see this setup being just fine.

How hard would it be to get

1 zip per plant
32 plants total
1200 total watts
37.5 watts per sqft

totaling over 32 zips on the low end but could it be possible to get 2 zips per plant with this size room and light setup?

I am doing this all in fox farms and using their organic line all the way through then tossing some molasses in there. The strains will be -

Super Lemon Haze (16 clones)
Grand Daddy Purple (16 clones)

Hi. I ran 1200w in an 8x4 room with 12 OG kush clones and yielded approx. 24 ounces+. I vegged for to long and I had trouble keeping my plants up right. I think with 32 and shorter veg you would have much better luck and 1 ounce per plant sounds completely reasonable. That is my next attempt.

Yeah you will be fine throw them into flower in scrog. kepp them somewhat short and topped I think you just might get those 2 zips per plant. My last show turned out about 1 1/2 zip per plant, good luck

Medmaker, I'm running 2 600watts in a 5foot by 5foot square. Its alot easier for me to water and take care of the girls. Your going to love the buds you get! With 1200watts.
Just my .02

 

[irieeyes808]

Hey guys I have grown last few grows with a 600, just bought another but it's a digital ballast and yeah just wondering what would the optimal area be???? We need a 6oo thread? Medmaker, Boevo, you guys have pics of the space your using. I have about 5.5 x 8.5 ft twin 600's will be about perfect im thinking cant wait to see what these will turn out. that

There's a 600w club thread, that might be what you're looking for.

I will get pictures setup once I get all of the materials together. Right now I am thinking about air temps and if I should just setup an a/c for the area. I think a 4x8 with 2 600 watts and the reflectors I will be using is going to work great for a scrog setup.

ON the watering I was thinking of doing a "beer bong" funnel style of setup so I can just toss the hose underneath and fill into the hose. Thought of an auto water setup but I think I want to get the basics setup like temps and amount of plants before I worry about trying to make it hands free.

With the hot temps about to come, I think an a/c is going to be something I will need to do, more money BUT worth it in the end if temps get out of control.

Using this box idea as a starting point for future grow room/cabinet builds. Trying to get all the bugs out, something simple to setup and take down if needed and cheap to d.i.y.

Odds are I could cram even more plants into this area if I decided to run the plants in 2 liters or something smaller than the 12x12 5 gallon square plants that I am looking at.


Do you think more plants in 2 or 3 gallon pots will produce more weight than 32 in 5 gallon pots?

medmaker, I can tell you right now that you're gonna have cooling problems. They room will be sealed, yeah? How is that room gonna be vented? Heat will slowly build up in the their.
Imo, get an a/c. Mini split units are great, but pricey, I paid $1100 delivered for a 9000btu unit.
hoosierdaddy has a great thread about building ac boxes, so you can use a window unit without a window.
2 600watters in an 8x4 will give you VERY nice coverage.
Are you hell bent on those reflectors? Sealed ones would help keep temps down, soon as you add a fan to them. Like, say, 2 super sun-2 hoods.
Sounds like you'll have a nice room set up soon, goodluck

 

[medmaker420]

I am going to run air conditioning either way, I have some purple that at the end of flower I want to crank down the temps for deeper purple tones. Might as well have it setup from the get go and not have to deal with temps and focus on other things like topping and working the scrog itself.

What would you suggest a/c unit wise for this sized room?

8 foot tall
8 foot long
4 foot wide

I am thinking of doing forced a/c intake to a passive carbon scrubbed exhaust. I would assume that the a/c will have enough incoming air pressure for this to happen.

On the reflectors, I want the large parabolics for the coverage I see them providing plus I won't have to run ducting and instead just setup a passive scrubber/exhaust setup. I am still contemplating using cool tube style of reflectors but with the a/c itself plus a oscillating fan blowing on the canopy, I see things working out just fine.

Still wondering if cooltube/ducting would be a better idea. I see the parabolic style of setup having less shit up top or needed. I hate having a ton of ducting inside something like this. I know with a cooltube I could get the lights closer BUT I see the parabolics giving better light coverage.

 

[Guest 18340]

Check the stickys up top, theirs one on calculating ac size.
Pico did a thread testing diferent hoods. Not sure if he tested the parabolics (its a loooong thread) but give it a read, it might change your mind about which hood to choose.
The tubing necessary for cooling the hoods is really not that complicated. I do see where you're coming from; wanting max coverage.
Cooltube are the easiest to cool because of their "straight thru" design, but dont give the best coverage. I had one.
No matter what route you choose, para, cooltube , etc, and AC unit is definately a wise choice.

 

[medmaker420]

thank you for the advice for sure, yes I think an ac would be the best thing whether I can keep the temps good or not. If anything I can bring out the purple in my grand daddy purples a bit more odds are being able to change the temps in the cabinet. Plus not having to stress while i'm out wondering if the temps are cool.

Any thoughts on how to rig up an ac to a 4x8 cabinet in a stealthy style? I am going to have it either in the garage looking like a storage cabinet or inside as a large wardrobe style of closet, either way I don't want a big ol window mount sticking out the side of the cabinet in any fashion.

Any fan suggestions from anyone with this size cabinet/room?

I will give that fan size sticky a read as well as the one on the reflector comparisons, great info and I feel I will end up building a bad ass cabinet. I am going to rig up a wired camera to it as well so I can check it from my tv or computer as well as look at the temps and everything. With camera prices these days it makes too much sense not to rig one up. If anything, if someone jacks you... you can see who it was, save it live to the computer or something.

Sorry I trailed off lol....

off to read some stickies on fan sizes.

One one thought

I am thinking between the 12x12 pots (5 gallon) or the 8.5 x 8.5 pots (3 gallon)

I can get 32 of the 12x12's in there or I can do 55 of the 8.5 x 8.5's

Do you think it would be more beneficial to run MORE plants in 3 gallon or LESS plants in 5 gallons.
