Alright, let me give the details. Im building a light proff and air tight box out of half inch ply wood. It will be 8 feet high, 8 feet long and 4 feet wide. I will make two 4 x 4 x 8 flowering chambers. I will most likely have 2 Sun Blaze High Output 4 Ft-8 Lamp Fluorescent Grow Light's hanging about 3 to 5 inches from tip of plants. I will have 1 plant per sq foot witch is 32 plants at about an oz a plant which = 2 pounds. The top chamber will produce 2 pounds and a month later the bottom will produce 2 pounds. Ill making a 3 b 3 by 8 mother / clone box too. just use cfl's for that. As soon as my clones get good root system, ill, ill put them into flowering. That system will allow me to grow 2 pounds of bud a month. I would use hps lights but cant deal with the heat and not enough room. Its pretty amazing the set up i have. Itll cost around 1800 bucks to get it all finished. Itll be a soil grow. As soon as a put the clones into flowering i am going to bend them at a 45deg angle so ill get more bushy and short plants with more bud. I need so expert advice on anything you think I may need to know. But please, no crap abt the sun blaze system, itll grow nice sized buds, dont have to have hps. Thats a fact. So, please, anybody got nething at all to tell me, and let me know what you guys think about my set up. I have a spare room somewhere that ill have this stuff in. And for smell, ill be useing dryer sheets in my 6 inch ducting along with a 6 inch inline fan in each flower chamber. plus a small hanging osculating fan in each chamber. let me know. Thanks guys.
2 pounds a month. Need some advice

Ill be makein four 4x4x4 chambers insted, that way the bright white walls can reflect more light to the plants. its better that way.

hmm, not sure what you want from us. Seems like you are pretty damn sure about everything. Lots of factual statements. I wont give you shit, but I am designing a room thats very similar to yours, but using HPS (3 600's.) I hope to get 1 pound per month and that would be good. 2 pounds per month seems ambitious from the t5's/

4'x4'=16 ft2=16 plants x 1oz per plant. Don't you mean 1 lb harvest each month?
I think you're set up to have good yields but each of your chambers is producing 2000 lumens/bulb= 32,000 lumens. A 600 watt hps (the standard for growing 1 pound) produces 88,000 lumens.
I think you're looking at 1/2 pound per month if you're lucky.
You added the thing about 4 chambers. This calc was based on your 2 chamber post.

But in real life I don't think it will happen. And I am not stating this as specultion but as fact from a grower (me) that gets 3+ lbs a month (dry weight)... It took me close to a year tweeking my 8 x 12 flower room that maintains a 160 plant perpetual grow. Dealing with clones, mother plants, low temps,high temps hi/lo humidity,co2,spider mites ect,ect When I first designed and built my room I crunched numbers of plants,calculated the number of grams produced per m2 according to seedbank descriptions calculated lumens x watts x blah,blah,blah The end results were not the numbers I crunched on paper.
I hope you succeed my fellow grower but if you have not grown on a large scale for a commercial yeild it's not as simple as just crunching numbers.
I am not trying to burst your bubble of expectations, just stating real life experience
good luck

thank you for your help and providing me with useful info. btw i did mean 1 pound per 4 x4 x4 chamber. also its 50,000 lumens per light system. so all together thats 200,000 lumens. yall really think one pound chamber isnt likely? they will be in a really good enviorment with plenty of fresh, cool air and plenty of room to grow. bending them also produces more bud. i had a friend who was doin the same thing but only one chamber and he got a lil more than a pound of dry bud per cycle. thanks again for your help and again, please leave more comments. the more yall leave the more i learn.But in real life I don't think it will happen.

If your shooting for the lb a month, them bending them (super cropping) will slow them down a bit plus I don't think you have enough beef in your light system. I am currently doing 11,200 lumens per sq foot as compared to your 3125 per sq foot. Plus you either need a co2 system or you will have to vent in fresh air and vent out stale co2 depleted air.
Ok, I see that I am going to need more light. I throw in 5 100 watt cfls in there too. Thats an extra 500 watts of red spectrum light.Ill have 2 inline fan goin 1 hour on one hour off so there will be a lot of frest air goin in there. It will blow old air in the attic. Man, I dont get it tho, he didnt even have a light system as good as Im getting and he got a lil over an oz per plant. 16 ox = 1 pound. Also, Just incase nobody knows this, marijuana really likes red spectrum light when flowering. HPS lights put out the spectrum and alot of heat that uses extra watts. As long as its getting plenty of red spectrum, lumens really dont matter. And my t5 system is going to be all red spectrum. And itll be rite on the plants pretty much so itll absorb all the light insted of wasteing alot and rejecting every other spec that a hps puts out. Ive always heard hps were better but alot of shops in amsterdam use red spec fluro's. I dont mean any disrespect or anything, I just wanted to point that out. Led's are the best but so danm costly. and they bearly put out any watts or lumens, just 100 percent red spec, and thats why they thrive under led's. Of course you can get blue for veg or mix it up but yeah, marijuana loves blue for veg, and red for flower. And please, dont just assum im wrong, Ive found this after many months of research, and books and grow videos. hps is good cause its so bright, but thay have to be keept far away from plant where this system im getting sits rite on the plants and is giving off flower loving red spectrum. Im worryed tho, because you guys are experenced, and know what your talkin about, and thats why im not doubting you guy's but, have any of yall ever tryed this light system and know that its not goin to work as well as im thinking? Again, thanks for all the responces, keep letting me know!
Good luck to u man. Stay positive and produce some good holy grass. Whats you room details?

Don't believe everything you read...LEDs are NOT the best if they were then everyone would be using them. For flowering HPS is the best IMHO and you don't have to keep them several feet off the tops of your plants. I run my 600w HPS 6 to 8 inchs off the tops of my canopys with no burns or stress because I use cool tubes. As for your friend that had less light than you are planning on using and he still made a lb....I seriously doubt it was dry weight if in fact he even did an elbow at all.
He didnt bend his, ima do that myself. However it was dry, I was with him and I was involved with his grow for the most part. I was there when he hung em, and when it was ready to smoke, we weightd em. I should check it out but he said he found somethin on youtube about green man or something where he had plants that grew abt 2 ft tall and bared over an oz of fresh fruit. lol. But no man, im serious, But i didnt know that you could keep your hps so close. Also, led's are soo pricey, hardley anybody can afford it. I seen a vid, where they grew a weed plant with a led and one with hps and the one with the little led that covers 2 sq foot that cost danm near a thousand dollars put the hps to shame. It grew faster, thicker, produced more bud, and has like no heat. But everybody dont have one cause is would take emptying your 401 k to get enough led to cover a 4 by 8 area. I mean just one 100 watt round ufo lite cost 500 bucks and covers 1.5 sq ft!

i have seen t5 produce 1 ounce buds. they were lollipoped. It was riu. VictorVicious does that or did. Sog style like albfuct but with 8 bulb t5s. It seems as a sog t5s do ok for buds. Co2 would be a 200 -500 investment that would be killer and not bad on finances if you bought it spererate one peice at a time. Half to one ounce a plant lollipopped in hydro coco ebb and flow or rockwool I beleive.

Thanks man, gonna take some pics soon for the site. But I am going to go on a limb and plead with you to use HPS bulbs. Dont mess around with all those CFL's that will add up to the wattage of a 600w, but without the punch and lumens. I want to get 1lb a month as well, and have a similar space. Using 3 600's I think I will achieve this. Not based on what I read, but my experience. I know you have done a lot of reading and research, but once you see what HPS can do....its all uphill from there. Good luck to you, take some pics so we can see the space?

And I can confirm, you dont need to much height with HPS. Just heat control! I had a room that was/is 6ft at the most, maybe slightly under. I had a ebb/flow tray (4X4) which took up a few feet of that space. I had 9 plants, and had to keep the lamp all the way up, and keep the plants relatively small. Last 2 grows yeilded 17oz, then 20oz. 2 oz per plant about. But it took me a over a year to dial that in.

this sounds a little ambitious, even at 1 lb a month......

It seems as though your configuring your setup and operation based on "your buddies" system that you almost swear he got a lb of bud from with less lighting then you are planning on using..My question is why are you asking us for advice??? you should be at your buddies place taking notes and picking his brains since he has in your words pulled it off more or less. Pretty sure it won't happen but good luck.

i was shooting for a 1 1/2 on my first op with a 400w hps hort. eye but what i am looking at in reality terms is close to half a p + or - , i am at least hoping for an o per plant. pics in my sig if i could offer you any advise it would have to be start with one 4x4x8 or 4x4x4 and finish the cycle before spending like crazy maybe on the second if you feel you did get your quota then go a head at least you could have some spending cash for the rest of the set up.theres one guy one the forums here named heath now he gets ridiculous amounts from each set up he had two trees with over 70 oz with a few 6 ers he dont use c02 and never passes ec of 1.4 (700ppm) through out his whole cycle and the pics are there to prove it. but for me to achieve that my first grow and my first set up even with all the knowledge in the world and not a grow of experience , do think i could do it. i know you said you were there and helped most of the way through but there lots of variables strain,climate,exposure,nutrients,enhancers,water,lights,jealousy and man i am sure i am missing quite a few things here. im not trying to knock you off you pedestal but if you aim low and get high i think you whould be happier no then vice versa. but it s all about trial and error as will find out
