thats not too hard thats a lb per 16SF. you should be easily able to do a lb per 10SF. heres an RIUer yielding 6 lb in an 8x8 with only 2000W and very very little cooling required at that efficiency

as for "quality" , well, the numbers are there. "quality" is all a factor of your ability to keep them healthy, train them, manage the canopy, and trim out the stuff you dont want

Fair argument. Now what is the quality of his tops or new COB lighting vs. a DE or newer technology HID light.
usually tops under led are better quality than HID. denser and less heat stress. quality is prob one of, if not the #1 reason most LEDers use LED

yeah i ran across that thread today i want to see how long he vegged and plant numbers to yield that.

@sgrowdum this comment is un true. Im not trying to be a dick, CobKits is a well respected member here, but quality of buds is on the gardener. The gardener is in control of everything in his/her garden.
well lets not call it untrue. maybe not universal, but *i personally* have always had better quality under led for years now. and i agree mongo, as i said above, quality is ALL on the grower

It seems that a lot of the larf control comes down to how the plant is grown as well. It is interesting that most here want scrog looking canopies that lend to nice tops with larf bottoms.
We need to see more cob grows with single cola plants or larger plants opened up for light penetration to see where quality truly lines up with hid.

You could run 4 of the Gavita 6/750's in that 8x8 and do very well also

Good point. I would say that the 6lb 8X8 guy did exactly that. i started a personal conversation with him asking what percentage of the 6lbs he sees is larf. Also i agree with the 4 DE lights but man that would create a lot of heat in that tent. the temperature where im at is warm too so controlling it will be an added PITA. thats why i originally wanted to go vertical again, less lights.

A pound per 10sq ft is easy. I yielded 480g in 10 sq ft with 400w of CXB3070s @ 45.5% efficiency. I can see 6lb with 2000w of LED no problem. I have yet to have my harvest numbers of my latest grow but with 1 low yielding strain, its hurting me a bit (although its killer stuff so Ill take the trade). I am thinking Ill get 2.5lb+ (partially harvested) right now with 600w of CXB3570 (56% eff) and 400w of CXB3070 (45.5% eff) in 32sq ft.

My Vertical adventure led me to massive gr/w but I didn't like the quality.
Though I was running monster bitched vegged 2+ months on a trellis. Nice branch tips and the rest kinda larfy hard to trim, but hey - I got the gr/w lol
you could do 4 air cooled 600's also or even 1000's depending on how much power you want to burn.
Admittedly, I have not read this whole thread so could be way off what your trying to accomplish

Yeah and thats what im avoiding. I want 4-5lbs of top grade herb not 3 and a pound of larf..

Quality can be higher with LED grown bud vs HPS. It's not a falsity. It's really quite simple. There is very little IR in led vs any HPS. HPS has a lot. This extra radiation degrades the terpenes and essential oils with no real benifit elsewhere.. Can HPS produce great quality? Sure can. Can the right LED? Absolutely. Will switching to LED make your Mexican bag seed a cup winner? Hell no. Will HPS make a cup winning cut into crap? Nope. What it comes down to is really simple. If you have the extra money for a high quality LED and you are going to stick with this program at least a couple of years definitely go for it. If you plan on doing this for a little while then changing up or upgrading buy cheap HPS. Being in a tent naturally the lesser wattage to achieve your light level goals the easier to control your enviroment will be. Also though if you are going to not use more than 2000 watts of hps in an 8X8 you should be able to control your enviroment really well. I am not a fan of an open bulb greenhouse fixture in a tent at all. If you are going to go with hps i suggest an ac/de or similar. Growlite makes a reflector that's duct cooled that looks like a gavita. If you want great quality id look into adding UV with either hps or led. 1 t5 agromax pure uv would go a long ways in that space.


Now personally I've used 1000 watts of hps in a 4x4 and 600 watts of great quality Led in that same space. I did really good with both but the LED for me was much easier to handle. You have plenty of room I that space though so a portable a.c. would be easy in there and add co2. Do duct cooled hps if you go that route and you'll be in good shape with your enviroment. Make sure if you do portable AC to get the one with 2 hoses!

I'm aware there isn't a magic fix for the quality. I've had my fair share of grows with wins and losses along the way. 8X8 is a good size but can start to get hot real quick if shit isn't on point. I do have a soare 12k BTU unit can run so it shouldn't be a big issue if I ran a few 1000's. Maybe the answer here is a 600 or 1000 per 3X6 table and some COB lighting combined.

Another good option would be 2 315s over each 3x6 area.
