Experienced Grower Desires Input From Other Pro's on YIELD, HARVEST DATE W/ CO2

So hello everyone. First time posting, long time reader. I've been gardening now for 3-4 years and recently expanded to a larger system after working through all of my growing pains. I currently am running:

1 10 x 10 Jardin Grow Tent
33 Plants, 5 gallon containers soil, veg 2 months
3 1kw HPS on 6 ft light rails (circular max distribution hoods for these lamps)
1 600 w HPS stationary in the back center
CO2 tank system with an environmental controller keeping everything dialed in
ppm's are currently at 1250 during the day and 550 at night, during weeks 1-2 they were at 1250 ppm, then 2-6 dropped to 950, now back up to 1250 for weeks 6-9??


The exhaust from this tent is then pumped into

1 5 x 10 Jardin Grow Tent
2 600 w HPS stationary with 10 plants, 5 gallon soil containers, veg 2 months
SCROG Setup
This room is having the CO2 filled exhaust from the other tent pumped into the intake.
The SCROG in this room is completely filled as the 2 month veg has allowed for a nice even canopy

This is all then being timed to exhaust into the rest of the open air basement room at certain intervals to maintain slight negative pressure in the tents. I know I'm wasting CO2, it's incredibly cheap and readily available to me (lucky me!!!!) so I don't care. I get about 2.5-3 weeks a tank doing it this way so the cost is negligible, just not ready to switch to a fully sealed room. temps are steady at low to mid 80's during day, low 60's at night.
I'm using Botanicare Nutrients Line and am also supplementing with good old molasses.
I have about 3-4 weeks left at most and was wondering-

What do you think my expected yield should be considering all these factors?
What would be the ideal plant technique for this type of environmental conditions (same tents, lights, CO2) Looking for input on plant techniques and plant counts as well as strain suggestions?

I'm currently running about Barney's- (50% Sweet Tooth in the 100sqft, 25% tangerine dream, 15% g-13 haze), and 10% Purple Power Plant. In the 50sqft, I have a tent of 80% blue dream and 20% grape ape.

Any thoughts? Hoping to pull in between 7-10 lbs, though I think having some of those sativa-ish strains in there are going to affect my ability to do that.
 
you have 3600w total. 3600/100 ( your grow area) is 36. so you have 36 watts per square foot. 40 is ideal, even a bit higher, but 36 is ok but not great. The rule of thumb is 0.5 gpw ( grams per watt). so 3600w/2= 1800 grams. I'll add about 20 percent yield increase for co2 and nutes and trust me 20% is being generous, so thats roughly 2200 grams. thats 5 lbs...

you can count safely on 5 pounds.

So that's not counting the 1200 watts in the 5 x 10 with the SCROG. So should I assume I'll pull at least one or two out of that separate tent?

I have a feeling you're a little low on your estimate, I'm thinking it'll come in at around 7.5/8 for both tents. I've got 3 light movers which are supposed to increase coverage by 30%.

I suppose we'll know in five weeks. Does anyone else want to proffer a guess or make a suggestion?

im guessing 7lbs total with the 1200w tent. your powerplant will yield the most I think too.

I'll say 6.5-7 lbs.
 
your weeks 6-9 at 1250 ppm seems kinda low for plants that have been vegged for 2 months. Are you using neutral or fertile soil?

Happy Frog soil straight from the hydro shop. I've been reading on CO2 and have heard that using CO2 about 1500 ppm is a waste and may actually inhibit senescence. Don't know if I'm running enough light to warrant those extra ppm's.
 
Barely enough watts/sq ft to use co2 but it certainly can't hurt. People usually drop ppm at the end of harvest, not in the middle. Anyways, getting off track. I say 6.5lbs of good bud.
 
You're a pro....asking for people who haven't ever seen your plants or grow habits to guess your yield? If say you should know better than any of us. Shit I knew a guy who ran 5200 Watts of light..and cropped so light he bought smoke off me consistently. Definitely not.saying you would do such a shitty job. Just saying that's a hard one to ballpark with only sq ft and Watts. Used to pull about 6 to 7 lbs out of a 4 K watt room with come enrichment. For.some reason the 8K watt room next to it would pull 15 on avg with only double the light.
 
It was going for 4K a lb and it was more like 21 or 22 lbs every 60 days with veg done at a different location.

Speaking of light movers. Yes they would increase coverage but they won't increase your yield much. The light movers will even out the canopy and have more better quality nugs rather than having popcorn fluff buds on the bottom. I use the light movers myself. The sole purpose for me, would be, I won't have to move the plants around as much as stationary lights would need.
