believe i know running sealed is superior but removing a watt of energy still takes x amount of btu to do so.

I don't have air cooled hoods I have DEs right now. but if LED perform like air cooled hoods then that a giant leap forward compared to DE's

thanks for the help man so: 13920/.92/.95 (at 230v) = 15926w total watts in LED lights. this doesnt include the wattage that the fans 10 or so wall fans dump into the room (55w ea x 10 = additional 550w) = 15926+550=16476 thats 56,216.112 btu's to cool this room with LED (1x 48kbtu mini split...

Looks like I would need right at 48k btu to cool a room with 14k watts of led

I've been through all the calculations sealing the rooms using 1kw de's and adding HVAC is impossible on my 200 amp residential service. It's not in the cards.

With 1kw DEs the typical rule of thumb is 5k btu per light. If your running dehuey and co2 burner then it goes to 6k btu per light. With LEDs like 288 boards what is the typical rule of thumb for sizing HVAC? I would have a room with 58x 240w lights so 13920w total LED lighting.

Here's another thing I need to think about. If I were to go with boards over bars I could put that extra 4k or so into a couple mini splits and seal the room now. I bet I could get away with sealing the rooms if I don't need as much HVAC requirements.

Ya, im still looking at the folux 240w kits. they are super cheap for the wattage and diodes. i can outfit my whole grow at 40w/sqft and custom 90cri 301b diodes for 6600 bucks its just what Rita told me, which now i believe she might not know the specifics. theres no way they have 2x 288...

could they be rating it at 1a max due to cheap china connectors or cheap pcb material? it doesnt seem correct to me either

I wish adding ac and sealing the rooms were an option but I'm limited to 200 amp service so I decided I would build the rooms around direct exhaust for climate control. It's a bear but I've managed to make it work good enough for 2-2.5lb per light yields. If going led helps with the amount of...

Meijiu: 288 board voltage is 48V and 1.09amps for one board

This is 1 room out of 2 but I'm already at 80 amps for 16 lights by themselves. Then my second 12 lighter room uses 60 amps for lights alone. There's no way I'm adding another 60 amps of power draw for 8 tons of HVAC on this 200 amp service with the additional power requirements of a typical 3k...

Sealed with cO2 isn't a possibility. I currently run scrogged and "lolipop" or defoliate under the scrog to get my 2.5lbs per light number. Keeping the environment stable is a real chore in a 16kw de room with the amount of heat they dump in. My hope is that switching to led means I can have a...

Sealed rooms with ac is not an option. This would require commercial sized electric 400+amp service ran to the house. I'm not sure if people are getting their high yields in non sealed rooms

Not mass but close enough here in southern maine.

So you're a budget minded medical caregiver grower with a 24x24x11 room trying to swap from 16x 1kw DE's to LED's. Do you spend 6600 bucks on 58x 240w Chinese 288 (Meijiu custom Folux boards with 100% 90cri LM301b Diodes) boards to light up 29x 3.5'x3.5' squares at 40w/sqft or do you drain the...

Rita fang: the cheapest to customize is the A8, what's more it support daisy chain, voltage also is 48V and 0.9amps per strip. 10k+ for 16x bar lights to light 5x5 spaces at 26w/sqft or 6600 bucks for 58x 240w folux boards to light up 29x 3.5x3.5 spaces at 39w/sqft I hit up geeklight about it...
