Seeking advice for RI medical grow.

[mordecai]

Hey, I'm planning a set-up for a RI medical grow. The limit for mature plants here is 12 at a time. SO:

My plan is to run three simultaneous 4x4 tents each containing a 1kwatt HID in a cooltube, one MH for veg and two HPS for flower. Each tent will contain 4 plants at a time. I plan on using CNS 17 grow, PBP soil bloom and liquid karma for nutes. Hand-watering coco.

Basically the plan is to stagger my harvests between the two 1k lights so that I'm cutting plants about once a month.

So if I am vegging 4 plants for one month and then flowering them for 8 weeks under 1k, is it realistic to aim for 1.5 lbs per harvest? The strain will be GH White Rhino.

Also, is it smart to plan on exhausting all 3 cooltubes in series through the same in-line fan? 440cfm sound about right for running through ~14 feet of 6" duct?

Anyone with insight into these two questions would be very helpful. Also anyone with general advice on maximizing yield with low-plant constraints is great. Thank you!

If this is your first grow 1.5lb from 4 plants under a 1KW is totally UNrealistic. I'm not saying it wont happen.

If you can dont run all 3 cooltubes inline. I wouldn't even recommend cooltubes. I have 5 sitting collecting dust.

As far as maximizing yield goes the easiest way for a beginner is to have as much light as possible. Think about using (2) 600w instead of 1Kw

BUMP

I've been wondering if it would be worthwhile to run 3 seperate tents with 4 plants each? Or would 4 plants with one month veg be under-utilizing the space(4'x4'x6')? I've been considering running a sativa-dominant plant like Mr Nice's Black Widow into vertical scrog in that space. Just throwing ideas out there.

I've been thinking of running two 4'x6'x6' tents with two month veg time using 2x600watts in each instead. Thoughts?

Last annoying multi-post: I'm not exactly a new grower, I've done several strains succesfully under a 400watt hps but have not achieved 1gpw as of yet. I just couldn't think of a better forum to post this stuff in.

4x600 is better than 2x1000 for so many reasons...max lumens per watt, etc.

also agreed that 1g/watt is not gonna happen until you get your room fully dialed...i'd be happy with .75g/watt or even .5g/watt lol

Any thoughts on the plan for 4 plants under a 1k with one month veg in a 4'x4'x6' space? Would that be utilizing the space or is it too much room?

Predetermining your veg time before you get started is also unrealistic. Set your goal for a desired height/size. Time means nothing to a plant.
