$50k-100k Warehouse V.S. Sealed room build

Jhef said:

Pro's and cons?

Should I outfit the warehouse with as many lights as I can and then HVAC it properly?
Or should we build a sealed room and limit the amount spent on light and invest in everything else involved in a sealed room?

in a 5000sqft warehouse (12ft ceilings or 25ft depending on the location chosen) and run 20,000-40,000w of LED would I need supplemental CO2?

What would my HVAC needs be in a warehouse compared to sealed room?

For one thing, you might consider making like 2, 3, 4 or more flowering rooms, this way you can stagger the crop schedules making harvest a LOT more manageable and allowing you to mono crop each room and you can properly clean and sterilize an empty room after harvest.

You don't want to just use an open warehouse, this will have many issues. If the ceilings are really high we don't want to hang the lights that high because of wall losses. It's just wasteful to have to condition all that excess air volume so if you end up with 25 foot ceilings you should make rooms with say 12 - 15 foot ceilings depending on your style of grow / plant count.

Wattage, figure 50 - 60 watts of HPS per sqft of canopy area. For quality LED figure 30 - 35 watts per sqft of canopy.

Rolling benches rule for large grows. Push them all together under the lights so no light hits the floor, pull them out one row at a time to get down through between those trays. When done push them all back tight under the lights. This works best when growing a SoG. For growing big ass trees one per light due to plant count limitations you can have aisles between the bigger plants and hang some vertical lighting in there to light the sides of those trees, this can actually make for more lit canopy area than if you didn't have aisles between the plants and allows less plants to fill a massive area and pull massive numbers. All depends on plant counts, you can get more crops per year with a SoG but you have to cut a shit ton of clones and you need a larger mother room. With big ass trees you have the veg time, part of that can be done in a veg room before moving them to a freshly harvested and cleaned flowering room.

@Jhef This is solid advice for you. How many grows this size have you done.
