54:00 – Thank god I am not alone in this thinking. All this horse shit about raising and lowering lights is only for much smaller scale stuff. When you go warehouse or greenhouse, if you really NEED to raise and lower the lights, you are either not as good a grower as you think you are, or you did something wrong along the way. When you stuff 50+ 1kw gavitas into a room, raising and lowering is in the past. You raise and lower if you do not have adequate lighting to begin with, like if you are growing at home and you only have 2kw, and you want a certain foot print.
51:00 – Sounds like ONA. It sounds like you have a custom design or set up that fogs the ONA at some point along the exhaust ducting. ONA does not eliminate odors, but instead changes them so drastically that they are no longer capable of providing the same odor as before to anyone or anything with a nose. They bind to the odor molecules in the air and simply modify them in a certain way as to over power, with "brute force", the initial odor/scent.
43:45 – Extremely expensive is an understatement. Those HVAC systems can cost almost as much as the house structure. Very expensive to operate too. But it is the only real way to control hybrid houses, or indoor warehouses.
Those research facilities in Texas that do tobacco for virus/vaccine research are 40 feet tall and have HVAC systems that run horizontal laminar flow, with two of the four walls constructed as wall-plenums. Horizontal laminar flow grow rooms, in hybrid greenhouses, will be the future. Horizontal laminar flow is brilliant for grow rooms because air circulation is handled by the air stream itself and not a bunch of energy wasting fans mounted on walls. It also eliminates the need for high % FFU ceiling coverage for air purification. You could just drop some IQair perfect 16s in the HVAC system for each room, or go even more expensive and get Stolz or something, even though IQair is EN 1822 anyway, and are used in medical facilities like operating theaters.
also one very important thing when it comes to supplemental lighting is having the lights mounted in such a way that you can easily change the height of the lights above the canopy. HID as well as LED lighting needs to be very close to the canopy compared to any other crop, otherwise you will have mayor issues with stretching of the plants causing weaker plants and lower yields. Another thing, regulations in many areas do not allow cannabis to be sold if a certain level of spores are detected so it is still important to prevent mold spores from entering the facility.

53:00 – IPM, IPM, IPM.
lol, sounds like me in my sleep.

33:20 – Are we talking ONA here? Just curious if that is what is mentioned, or if it is something else they are talking about?

37:50 very bad idea. Interrupting the night cycle for cannabis will promote hermaphrodites to appear potentially ruining your entire crop.
Very good info. Will you be doing something similar, but focused on indoor large scale operations?
