3x7 sealed closet Vertical / Coliseum / stadium, bare bulb, Blumat IDEAS?

Designing a stealthy op for an oddball room size 3’x7’ sealed closet.

Ive got a 3 ft X 7 ft with 8 ft ceiling closet I want to build a stealth Op in. Ive been brainstorming Ideas and Id like some input! The design will be centered around a few line items as follows: maximize space, stealth and reasonable wattage (I do have a smart meter), simplicity, max yield for the space given.

Equipment I am thinking about using:

1. 4x LEC CMH 315w OR 2x 1000w HPS w/ digi ballasts

2. G-leaf 1 gal air pot/grow bags

3. Blumat drippers into rockwool cubes backfilled with perlite. Or into coco... still unsure

4. I’ll need a mini split to maintain temps maybe 12-16k btu

5. Adj. shelving for future experimentation with spacing

6. C02 regulated

Questions for the Guru’s…

Can I use a HPS/MH digi ballast to run CMH bulbs? Whats the best/budget way to run a CMH bulbs?

Will the Blumat maintain the proper root moisture/feeding in a grow bag with rockwool and not need a drain system?

is this your first indoor garden ?

No its not. That being said my last vertical closet setup was back in 2009.

i love the design of a hydro vertical, leaks kill it for me.

I'm hoping leaks will be all but eliminated using the Blumat drip setup

I'm going back and forth on plant site numbers, lights, spacing, etc... at first I was thinking about 4 levels with 15 plants per level at 2 foot elevation intervals giving a total of 60 plants. I would also use 4x Philips cmh bulbs bare back hanging vertically but I want really dense nugs, so this may not be enough light, should I double these up and run 8x cmh bulbs?

Now the more I talk with other various friends the more I'm thinking about running 3 elevation intervals spaced at 2 ft 8 in high. This will give me 15 plants per level and 3 levels high for 45 plant sites total. Ive.also been toying with the idea of running 3x Maxpar 1000 SE-DE bulbs.

I'm trying to maximize yield for my given space. I've attached a pic let me know what you guys would do ideally with this space.

With the screen placed 1'9" away from the bare bulb I will have roughly 54 square feet of scrog area

nope, cmh use low freq, square wave ballast

if you can find a retailer to sell you a cmh setup without the reflector would be cheapest. just run bare bulb but make sure the cmh bulb is open rated.

With only 1'9" distance from canopy to bulb I don't think I can run the se-de maxpar bulbs

not positive, but i don't think you can run de vertically anyways. cmh is what i would do. i have one now (not vert) but it's better than hps anyday.

I'm mainly speaking about the se-de maxpar bulbs with the de arc tube encased in a single mogul base bulb.

Hey Rocky what's up man.

I got my shit for the next vert grow.
Stacked, upper lamp a 315W CMH and the lower lamp will be the 400W HPS. Had hope to get another good deal on a 315 but it fell through so the 400 is the backup. 5 plants screens.
Look for my sig and take a gander when you get a chance. Was to be a winter grow but going to be spring early summer harvest.
