40kw legal vertical grow

[Aeroguerilla]

Hey so im getting ready for the new laws up here and getting the new setup ready for october 1st

Plan is 80 plants 50gal smartpots 2 per light vegged for at least 2 months

I was thinking about just using the reflectors and pumping the heat right out the the chimney but at the same time after looking at all these vertical threads i think its time i change it up.

so how do i cool 40kw barebulb efficiently?

fully open to any tips, comments or concerns. let me hear it ALL

size of the room is 45 x 25'

40 KW .....? 40 1000w bulbs .....? holy shit! however you cool it please post some pics!

 

[Bobby Stainless]

Sounds like a winner!

What are you putting in the smart pots?

 

[nickman]

wow man, i wish i could help ...

i'm watching this 1 if ya dont mind ...

not sure the best way to cool that much heat. assuming its a building with 10ft ceilings.. the air exchange rule or whatever would be 45 x 25 x 10 x 2 (if 10 is the height) = 22,500 cfm to exchange the air twice per minute if im not mistaken..

def go bare bulb in an x o x o x type of pattern. no tubes or reflectors. try to make the pattern where each plant is getting hit by 3 sides of light at all times. a few will receive 4 sides if you do the pattern correctly. you might need 1 or two sante fe max dry dual XT dehumidifiers; and pivoting fans under each bare bulb blowing the heat upwards. veg 8-9 weeks from 6-12 inch clone. you need 3-4 ft between x and o's. If you can manage it, I would blast all lights, no flip-flopping. You won't need 40kw for veg so you could flip flop the veg period.

I think we might need to take the roof off your grow room That's a lot of juice aero, your gonna need something like 10,300 CFM of ventilation. If you can, Floor Fan>Bulb>Extraction. Rows of 5 1k's x 8 with over head ducting sucking out each bulb individually would be great but it will run you back $$$ and even at that your going to need 2060 CFM on each row, I know you want to run it efficently so it might not be the best option for you. I've never run anything near that so maybe some of the big boys can help you out.

right... I run a show w/ dual 1800w light stacks.. Not even gonna try and give advice on this one. 40K in light? I'm taking a seat.

 

[BigDawg]

i don't think you'll be able to do 40k watts in that amount of space with true verticall trees.

this would be good for a 40 x 20 : x = L O = p 23k watts

X O X O X O X O X

O X O X O X O X O

X O X O X O X O X

O X O X O X O X O

X O X O X O X O X

as you can see all plants are getting lit on 3-4 sides. a true light house.

if the building is insulated properly you could run 8 ton worth of a/c for the above setup with CO2.. throw a couple of good size fans/carbon filters in there and a VaporShark industrial odor system if needed.

Pretty simple really.

if you want to run 40 lights in that space you're gona have to go horizontal with twice as many plants and only the tops will get blasted, so not nearly as efficient as vertical.

moving that much air is going to be an issue but it can be done. if smell is also an issue it is gonna be a pricey issue. with that volume of air can filters are gonna have to be delivered by the truck load ...... i am sure they make commercial carbon scrubbers, but i bet they don't come cheap either.

if you are going to try to run the thing sealed you would need a huge lung room with some serious tonnage in AC. there will be some engineering going into this one to make it work ....... does not sound like this is a home depot kind of project

 

[turbolaser4528]

damn dude! what happened to the outdoor/greenhouse grow(s)?

Where your at, does it even make sense to go medical?? jw, was thinking about relocating.

Best of luck my northeast brotha

How about sealed room and 3.... 5 ton climate control water cooled Ac's what ya think? I ran sealed rooms with the cubas in Florida this way.

 

[Dr.Dank]

No commercial growers use carbo scrubbers lol sealed rooms All day even 500+ lights trust me is the only way to make it sane.

 

[250wscrogger]

You will need 4x 3 ton A/C's........................

40k? Time to get a warehouse!
I would suggest two 20k rooms on a flip with 2x 3ton mini splits and 4 santa fe max dry dual XT dehumidifiers in each room...

20 lights, 16 plants in each room. (25'x25' footprint) I'd go 36'x36' on the rooms for some extra space around the perimeter for working/equipment.

X=light
O=plant

How about TWO flower rooms so that only 20Kw will run at any given time?

Also if you were going to veg in place I would only run half the lights at any given time. I'm sure there will be more than enough light to veg them with half the lights off.

As for cooling, an operation like this would really benefit from a basement. The coolness of the earth all around concrete walls and floor really helps.

Since it is going to be balls cold in Oct. in your neck of the woods you may want to think about huge air exchange between the outside and your room(s)

These are my quick thoughts.

 

[praisehim.]

^^ what they said. split the the room in two. Get two mini splits ac's, somehwere close to 60k btus would work for each room. and that way you can pull trees down about every month, if you cycle the rooms.

cool tubes?

i have a friend with a warehouse that uses scrubbers ...... in the "hood" that he is in it would be a bad idea to telegraph what you are doing in the building if you were legal or not. the place is set up great, but for about two months of summer the AC on the building does not cut it. the asshole landlord does not care and the AC upgrade would run about $40,000 out of my friends pocket (and it would belong to the landlord in the end) so that aint happening..... he runs reflectors so he has a pretty big system that runs clean outside air through the lights and out of the building and he still has heat problems and DANK odors. there is no way he could run what he does bare bulb without a major rebuild.

2 20 light rooms will be much easier to manage than a 40. a horti makes a 20 light flip for just this app. have you considered SCL? staggered crop lighting? I know the cubans, dominicans, and peurto ricans don't know how to build grow rooms. I made a good living in 04-06 fixing everyones issues with that PIFF! 30 lights.. 30 plants. "We don't want to get to caught over the federal limit" I was going to say that Floriduh.. has a year round outdoor grow season too. perhaps the big HPS in the Sky under an environmentally controlled, SEALED green house or 2 would work much better.. since tha black usually gets vegged 4-5' is vert such a great idea??? this is one of the only cases where I would rule out strength in numbers and just veg everything and pretend the world was flat..

i have 2x16 light flips that's 4x8 light rooms. vertical bare bulb. i have a 3 ton in each setup, and attached to the 3 ton air handler is a bottom and top plenum with motorized dampers/relays. when the power is on the dampers goto one room, and when the power is off the dampers goto the other.

by far my favorite way of doing vertical. big a/c, semi sealed room. i run intake/exhaust at night because the plants really love the fresh oxygen at night.
