Consider it takes 50-70 days for most strains to flower/finish
If you don't have both a Veg space, flowering space the time will be greatly increased between harvests.
Say its going to take 120 days to veg/and flower out the 1st time around.
Before you put your plants in flower, you should make cuttings, and root them, veg them, and have them ready for the next go around. That's way these is 50-70 days between harvests vs 120.
1/2 oz a week for 60 days is 1/4lb. Easily obtainable.
I would get a High Yielding Strain like a Mr Nice Critical Mass, Critical Kush, Super Silver Haze... Some phenos of SSH go 84 days, but other phenos can be found 60-70 days.
Elemental Seeds Mango Tango
Elemental Seeds Grizzly Kush
Reserva Privada Kosher Kush
If you use a 1000 Watt Hortilux Super Bulb, 1-2 20 Gallon Container and 1 of the above strains grown Tree Style, if you cant get 1lb+ your doing something wrong. I always get at least 1 1/4 from the above strains per light... Often 2 lbs per 1000 Watt Hortilux, but as a Minimum, if you cant get an LB somethings wrong.
I also veg in a 5 Gallon Container x Promix BX, Sun Bulb Better Grow Orchid Fert. Both Veg/Bloom formulas, and 1000 Hortilux Super Bulb.
Also 1st time around, considering you will be Pheno Hunting, I would grow out a pack and get all the Females, and flower them in 5 Gallon Buckets as you need space for multiples.
Having taken cuts from each female before flowering, you can keep 1 of the Cuts that you decide to use as your Mother Plant for future cuts. You can pretty much get 9 x 5 gallon buckets with pretty nice vegged plants. If you get 3 oz per plant, that's 27 oz. I said 16 is minimum, but there is potential for much more.
A lot depends on Air Circulation/Ventilation/Temperature ect. Proper watering/feeding.
I got 65 oz from 2 Hortilux and RP Kosher Kush last month. Same for the SSH.
SSH is fast growing, and needs less veg as it stretches , and you can take advantage of the stretch if you know what youre doing.
