So I think everyone has talked me into just spending the extra money and going LED from the start. Looking more into them though I can't get over how large most of the lights are compared to old school HPS light reflectors. Would I only be able to fit four of the big LED lights if I decide to go with a light like the "MIGRO ARAY 12 PRO'? When I use the grow light calculator it says the ideal light for my room is 13000 µmol, and it seems most even 1000w LED are only 2,000-2,200 usable PPF. So am I going to be maxing out around 8,000-9,000 PPF and missing out on a decent amount of light exposure ?

in my mind I wouldn't get a 1000w led, I would a for like 800-500 watt led. The good ones that pull that much are what i think of as the equivalent. The bar style led lights are VERY big bigger than the blockbuster hoods. I'm personally looking into quantum boards as they are way smaller, I'm worried about penetration tho. I've seen bar style LEDs with ppfd that high that are legit I believe, are you checking that it's for the right canopy distance?

I'm trying to do something like this to so I'm excited to see what you do. I got my Quantum boards from Alibaba but they are the sideking SK-4000. 250 for each, but they offer 20 of them at 160$ a pop. that brings your lighting cost down to about 3k and you should be able to provide all of your flower and vegging lights

Does anyone have any advice on how much a/c I'm going to need for a room this big ? When its all said and done I hope to eventually have my 10x20 space divided into two rooms, a veg and flower with (6) 650 w LED lights in FLOWER and (2-3) 650 w LED in VEG. In the summer where I live in can get in the mid 90's often and barley gets below 70 even in the winter. I know the LED's don't put off much heat so do you think I would be able to get away with two big portable A/C units or what would be your suggestions. I personally would rather go on the bigger side of a unit so it would always be struggling to keep it mid 70's at all times in both rooms. Any advice from someone more knowledgeable in this are would be greatly appreciated.

veg room
2x 650 x 3.41btu = 4433btu

flower room
6X 650 x 3.41 btu= 13299btu

oscillating fans 55wx3.41 = 187btu per fan
8" inline fan 190W = 650btu per fan
70 pint home dehumidifer 800Wx3.41= 2720BTU

I hate portable ACs they are so hard on power. And can barely cool up to their rating. A window AC would be much better if you can make it work.

also you'll be aiming to keep your temps at 80-85 rather than 75-80 as before.

the other problem I see happening here is air exchange. You may need to ad an inline fan somewhere to swap out the rooms air and exchange for more CO2 as the plants use it.

portable AC will definitely suck some of the rooms air out so be aware if odour control is important.

otherwise the best option really is a mini split. They are dead quiet. And waaaay more efficient. And if you are spending money on 8x LED lights. Do the job right and figure out proper environmental control. Hard to give anymore advice without seeing the layout. But imagine a 5x10 veg and a 15x10 flower room.

you likely won't need a Dehumidifier if your area is dry most of the year you can drop your room RH just by using inline fans for air exchange.

If you do a sealed setup with an AC and no outside air exchange you will have to supplant CO2 either by tank or burner.

OK I never looked into a mini split and could be a option. I definitely don't mind spending a little extra right now to have everything running more efficient.
I plan on having a few wall mounted oscillating fans in each room, as well as one or two inline fans and a carbon filter in both rooms before any air exhausts.
I would like to run co2 with a controller and tanks but need to figure out the best way to have my air exchange and not waste any co2.
Also I plan on actually framing out the two rooms this week so right now its blank space that is 20 feet long and 10 feet wide. I was thinking about either dividing it up 12x10 for flower and 8x10 for veg, or 15x10 flower and 5x10 veg. I just want to make sure my veg room will be big enough to supply the flower room with enough and bushy enough plants.
Im in a pretty humid environment so I will probably have to invest in a dehumidifier at some point.
Any advice on how you would best use this 20x10 space would be greatly appricated.
Thanks for taking the time to leave all this helpful advise on A/C units and air intake.

Storage is always my concern. I would totally do a 10 x 15 flower and 5 x 10 veg if I had a place to store my stuff to. If not, I would go with the 12*10 flower room.

Mini split is definitely the way to go.

I can veg for a 10x17 flower room out of a 4x8 tent comfortably. As in I can easily keep enough clones to fill out my space and cover some buddies when they need clones too. I think a 5x10 would be enough. Same time at @ 10x15 those 6 lights only give 26W/ sqft. 12x10 might be better for coverage.

I think more lower watt fixtures would better for the veg half so you can spread them as needed. I bet you could get away with less watts. Since currently you are still at 26W/sqft for veg room with two 650s. I think 7-900W would light the veg area OK.

Can someone help my understand the best way to run a sealed room with LEDs so that I can run c02. I plan on putting either a window a/c or mini split in both my flower and veg room and would like to run c02 with most likely tanks and a controller.

I'm just trying to figure out how you can have a sealed room with these new lights, as before I would just pull air from out of the room through my air cooled light hoods and then exhaust it.

Is there a simple way to do this with the new lights?

Do you just put your intake and exhaust on timers, or is that going to be too much of a waste of c02.
Any advice or suggestions would be greatly appreciated
