8 X 12 SOG Grow Room Finished

Each 3 X 8 finish table holds 80 net pots and will be covered by three 400 watt HPS lights.

You might consider changing to a 600w hps. Since you are going for efficiency here's why: The 600w hps has the highest ratio of lumens to watts. If you have two 600w hps that should replace your three 400w. Here is the ratio

400w - 50,000 lumens
125 lumens per watt

600w - 90,000 lumens
150 lumens per watt

1000w - 140,000 lumens
140 lumens per watt

You can see after the 600w HPS there is an efficiency drop off. You can liken the efficiency of the hps lights to a bell curve, the 600 watt hps being at the top of the curve.

Not everyone knows that but those who do get a much higher cost/benefit ratio.

True. 1200w, 180,000 vs 150,000 lumens, + cheaper initial equipment cost if you havnt already purchased for the 400w's.

the air running thru the cool tubes and sent to the attic isn't nasty. It is drawn from a source outside of the grow room. And when its vented into the attic it is dispersed thru the 3 turbines on the roof and thru soffit vents all around the house. In a few more weeks i will re-connect the attic out flow to my main central a/c -heat duct in the attic and use the hot air from the cool tubes to keep the inside of the house warm this winter and save on the nat gas bill.

Totally agree...I have not updated this thread in awhile but I sold all my 400w' systems except for the 2 in my mother room and replaced them with 2 x 1000w HPS over ea table. Ran across a deal that I couldn't refuse for the whole lot. But now I am waiting on some 600w digital ballast I ordered to replace these old style magnetic ballast. I am putting 3 x 600w over ea table and that will give total and full coverage and 112 watts per sq ft. Might be over kill but I'd rather have to much as opposed to not enough.

Well I think I am finally finished. I have replaced the 2 1000w lights over each table w/ 3 x 600w digital Quantums (6 total with one extra ballast as a back up if needed). The DIY nat gas hot water heater co2 generator is rocking. Reworked all my pluming for the two tables to work from 1 main 125 gallon nute tank. Right now I am averaging 24 to 28 oz (dry wt) every 2 to 3 weeks.

Now I am in the process of trying out new strains and incorporating UB's topping tech in an attempt to achieve my goal of 2.0 lbs from each half of the 3x8 tables every 2 to 3 weeks. Here is a few pics of my present grow...enjoy

wow just gotta say mad props to you brother! just read the whole thing and i think im gonna go to hydro im in soil right now but picked up a 60 site aero for some work i did. once i get all of it set up it would be awesome to have some feedback from you ill let you know whats going on prob a dead thread but still gonna subscribe

Did a great job on your room Tat!!! Always enjoy checking it out. Plants are lookiing great really dialed in your setup.

Thanks Nugs.Dialed in..yes. But not satisfied w/ my net yield yet. I'm averaging 22 to 25 zips dried on average every 2.5 to 3.0 week per 1/2 of my table (12 sq feet). Right now I am trying out some Canadian strains that look promising. Hoping to achieve my goal in the next couple months of averaging 28 zips every 3 week period. I chopped one a couple weeks ago that netted just under 23 zips. Gotta do another chop between today and tomorrow that might squeak out about 25 to 28 zips.


Peace
Tat

Very very nice man. So you are getting 24 zips per tray? That is great man! Bro I have to ask, I am running 2x1000k's over two 4x4 trays. Did you find an increase in yeild with the three 600's versus the 2x1000ks? I was about to buy two of the ocho xxl reflectors, but if the 3 600's are more effective than I may make the switch too.

Just checked your thread, Very cool! When I saw your avitar I went and looked at the post date....How did you get your avitar so quick after the Super Bowl? I made etched bourbon bottles for a Party at the Royal Sonnesta Super Bowl night, I thought I was quick!

I guess I am now averaging 20-24 dried zips per 1/2 of the 3x8 table (3'X4" area=12 sq feet) Trying some new strains right now to see if I can squeeze out a little more. But it will be awhile till I have a full table of the new strains with the phenotype I decide to keep. I have all but eliminated 3 right now and over the next couple of days I will be cutting about 80 to 100 clones of the newer phenos I have decide to keep and it will be at least a cpl of months to weigh out the results and decide if I will stay with them or start over with new seeds looking for that elusive genetically perfect seed.

As for your lighting question. when I replaced my 2 x 1000w with 3 x 600w the lumen output were comparable to one another but being less watts= less heat and being in cool tubes, I can almost set them on top of the plants w/o burning them and I have better penetration of light IMHO and I believe this has led to an increase in yield.



Thanks for stopping in

real nice did you get a permit?? LOL!!!!!!!!!!!!!!!!!!!!! it hurts, the laughter!

Wow man, that is very impressive. I will stay posted to see who the keepers are in your hunt for the ultimate indoor strain. It makes a lot of sense about being able to get the light closer and better light penetration. I would be running air cooled reflectors. I was looking at the dual 600w ballasts, I have enough room to even go with 4 600's over 4 3x3 trays.
I do appreciate u sharing your expereince man.

Funny you should mention that. Where I live, you need to get a building permit to put up a freaking cheapo 8x10 storage building you get at home depot in a box. It was actually tough building my room in the garage, I live in a subdivision where they are still building some new homes and I see the code enforcement dude driving by almost everyday. If he would have driven by while my garage door was open and seen the room under construction or while I was unloading some building material he would have stopped and asked to see the permit...

Perfect example of the fucked up permit extortion racket they have here, My neighbor was redoing his kitchen cabinets. While he was unloading them into his garage the code enforcement nazi drove by, turned around and asked my neighbor if he was doing some remodeling and he said yes, then he asked to see his permit or his application for an interior remodeling permit. He said he has never heard of such a thing. End results was he had to get a permit (a/k/a extortion $$$ fees) and have it inspected and approved or it would have to come down....What a f&*king joke.

No problem my brother. Will post updates as they happen.

Later

Sounds like Davis. A friend of mine that lives down there was just telling me the same thing about their permit extorsion. I heard you had to have a permit to put in a ceiling fan or a new light fixture. That is fkn nutz.

Hey Tat2, I wanted to ask you about your fan leaf trimming. Do you do a lot of large fan removing? I currently have a grow that is a bit crowded and am wondering how many of the large fans do you take off in the middle?

Complete newb to the site.

Very nice work BTW.

I've got a couple of questions I hope you can find the time to answer.

What size holesaw/net cups are you using. What centers/spacing did you drill your holes on.

I would be greatly in your debt for a few pics of how your fill overflow and drains are hooked up. I've got a few of my own ideas but it always nice to see a successful examples before I start spending money.

Thank you.

I have to do a chop tonight and after I am done I will take a few pics of the inside of my table w/ the plumbing setup and other info.

Since all my plants are packed in pretty tight I have to trim the big fan leaves a lot. but I only trim what I can get away with to keep light shining down on lower buds.
