Designing a 15000sqft facility....please help

[joe macclennan]

seriously though snaps. i like the harvest a few trays everyday idea. This would spread the work out making it easier to accomplish and ensure quick turnover.

 

[SnapsProvolone]

of course!

Shit. I'm the wrong line of work. I need to redo my resume. talk about benefits package.

 

[joe macclennan]

can I get some oreos and a gallon of milk with that?

 

[SnapsProvolone]

And a large pepperoni pizza with extra mushrooms.

 

[joe macclennan]

anyway op. what kinda medium ya gonna run in your hydro setup.

and how many lights are you thinking of running?

 

[SnapsProvolone]

I suggest using rockwool logs for tables on a large scale. Washing hydroton adds too many man hours.

I can't believe the op's consultant recommended large plants and not a sog. The man hours involved in trees (bud support) would be extreme. In a sog with trellis you make that a non issue.

Your going to be looking at a lot of lighting and cooling & dehumidification.

 

[SnapsProvolone]

Let us assume 20 working days per month. Lets say we want to harvest/reload four 4x8 trays each work day.

160 trays, 320kW flowering 100 tons of commercial chiller units and a buttload of dehumidification is going to require a massive electrical service. Even splitting the flower needs a 50 ton chiller. Note these numbers don't size any tonnage for normal building heatload, veg area.

 

[joe macclennan]

all sounds pretty good. Honestly, I hadn't given the number of lights much thought. but yeah, 2k per tray is what I would shoot for.

holy shit! 50 ton chiller minimum LOL

The biggest chiller i've ever been around was a 100 ton and we set this one on the roof of a college! lol

 

[SnapsProvolone]

El chillarator. Lol

Can't imagine the 'hydro' bill for all that juice.

 

[SnapsProvolone]

What gets done? Well accounting for varying yields and flower times with multiple strains will do about 2.5 - 4 lbs per tray, roughly 6 times a year.

Lets average 3 lbs per tray and 2 months flower (6 harvests per tray per year)

160 x 3 x 6 = 2880 lbs/year

So dumping 2.5 - 3 million into the build will net a return in less than a year of running full strength. Expect a year of operation to get it rolling full speed.

 

[jrainman]

Snaps good estimate ,I agree 2.5 - 3 million for something in that square foot range, but lots of unknown as far as location , don't know about Canada , but here in the US , the excavation could run a Million alone with conforming to DEP regulation ,being chemical (fertilizer) needing to bring in lots of different material for run off seepage ,building of run off ponds ect , ect . and also a nice generator system that could be run a certain percentage of the month .

 

[SnapsProvolone]

One would want a 500kW prime power backup with adequate reserve.

One will also need ro filtration capacity at about 2000 gpd.

Costs to build and permit are a big ??? I'm also not familiar with canadian regulations. Would sure want several lawyers to sort all those details.

 

[shawa]

Well we were planning 10 grow rooms of 1200 sqft each. And each room with 50 1k lights....so in total about 500 lights of straight veg and bloom. Of course this would be when reaching max capacity. In the begining we might have 2 or 3 rooms ready to go. Once they fill we add lights to another room and so on.

 

[shawa]

As well, Canadian regulations are a lot more clear than the US. Here it is legal. All you need is a doctor's prescription for it. With regards to growing, you need to get a license from Health Canada. To get a license you need to put together a proposal that involves the site plans, security plans, air quality plans, etc...As well, no store front is allowed in Canada. All orders are placed by mail or fax or online and all orders have to go out by secured mail.

 

[SnapsProvolone]

Building permits, inspections, ibc regulations and the like. Don't forget emergency egress.

 

[shawa]

All that is covered. Were working with an architect that has all that from the city. As well, a partner is building the warehouse from scratch. Basically, 1 of the 3 partners will be the landlord. The building will be 30000 sq feet and well have half. In the future if expansion is needed, we'll have first dibs on the 2nd half once that tenant's lease expires

 

[SnapsProvolone]

In your rooms, fire marshall may want proper aisles for emergency egress. Plan accordingly.

Decide grow method, then system footprint will determine best layout, lighting and cooling requirements.

From experience, when plant count is not an issue, go with a sea of green using flood and drain.

That's enough free info.

 

[Shaded420]

I don't see the point in this....the laws in Canada are changing/have changed.

Unless you happen to have the golden horseshoe up your bum and they've given you a permit.

that's what I was thinking..... plus a modest 1000$ donation for doing the work for the professional consultant

edit: or at least an honorary position @ QC
