24'x24' room 16x 960w China bar lights in 5'x5' VS 29x china 480w qb288v2 boards in 3.5'x3.5'?

p0opstlnksal0t · Jul 30, 2020

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 ol savings and go for broke spend over 10k for 8 bar 16x Chinese bar lights in dual 480w driver config total 960w (Meijiu A8 or MJ-650 style with custom 100% 90cri LM301b diode 256c strips) and cover a 5x5 square?

Unfortunately I cannot seal the rooms and add HVAC or co2. These are exhaust controlled rooms only

Right now in an exhaust damper controlled non sealed room I pull about 2-2.5lbs per 1kw light. I'm hoping to yield this same amount with less power and heat production.

Boy

I'm a fan of the 288 bds...use em in veg

Don't have the height for them in flower or I would.i use 132 bds cuz I can get em closer

288s is my choice

Have you maxed out your full potential in this room already? Nice DE lights are hard to beat in a big room. I'd probably put my money into a sealed room before blowing my wad on an all led setup. I've seen some killer mixed commercial grows with DEs and leds mixed.

2-2.5 is average for 1k de. I know some people who are hitting 4.5 per light with the Gavita 1k de and some who use the Gavita LEDs that are hitting just about 4. All sealed rooms. How you feed your girls and what you feed them is important. We tested just a basic GH formula usually what I saw here to what we do. The difference was literally 1-2lbs a light compared high 3s to low 4s a light. My advice to you is if you are already running 16 lights just stick with it. Run co2, get a controller for it set it to 1200ppm. Veg in 7g to 10g pots, lollipopping is key. Don't even bother with Chinese garbage lights. We ran 1k de Chinese lights compared to gavitas the difference was a night and day. We did the test again with gavita bulbs installed literally the samething night and day difference. Chinese clones of anything is garbage don't waste your money bro.

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

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 more stable exhausting and lower cfm air exchange to keep temp and the more stable. The lower amount of heat getting dumped into the room should help with yields if I have a more stable environment.

Why would you need a 400 amp service? We run everything on 200 amps just fine

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 SQ ft house

p0opstlnksal0t · Jul 31, 2020

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 air exchange I need due to less heat production I'll be happy

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.

Sorry I'm just kind of confused. I'm assuming. You have 2 rooms on a flip with your current setup? So why not just add co2 at that point? Is your AC/air handler dedicated to the rooms? If not just get a HVAC guy to come and do that. Then run your co2. I'll try to get some pics from my buddy who was doing Chinese LEDs vs his gavitas LEDs. Shit isn't the same man. Like not even close. Honestly upgrade your HVAC if you haven't, seal your room, run the co2 then decide from there on after. I'm installing a 3ton mini split within the next week or so

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.

SwiSHa85 · Jul 31, 2020

What your missing is adding co2 will allow you to run much hotter temps. I mean honestly 85f+ is normal in a sealed room. My veg and flower room are both sealed but my flower room exhausts to my veg room on a controller when needed.

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

Why not just run the separate rooms on a flipped schedule?

That way you aren't pulling 60A & 80A of lights simultaneously. You should be able to seal both rooms and run A/C no problem on a 200A panel.

Yeah im kinda confused. I have almost the same setup as him except my room width is smaller. I asked if he was on a flip too no answer so at this point i dont know. Just want to help him get a better yield than from some shitty chinese leds.

I have some 240w QB’s on the way for testing in a small room to see what the hype is about but I will most likely end up using them for Veg and continue flowering with my 600W HPS’s.

For a room of that size I would definitely stick with the HID’s for now, especially if OP already has them. I don’t think the investment is worth the return.

how do you run them flipped when they are in 18 hours for veg?

1 room isnt built yet but when its built out in the basement it will flip flop with the 24x24. so it will be fine when im running at 12/12 but what happens when one room is in veg 18/6?

if i tried to seal room 1 now with 16x 1kw DE's (1200w on boost/.96/.9

=1275w x 16=20400+550=20950w total = 71480btu thats a 48k unit and a 24k unit. so 6480w +2800w max ac plus 20950w = 30230w total if i kept the DE's so 125a total draw @ 240v in this one room. the room is ran using a 100a sub panel. i could theoretically rewire this sub panel for 150-160 amps replace the 300' run of wire back to the main 200a panel and run the room sealed. then the problem is running 125 amps on a house that can at any time during the day pull some serious amperage by itself. Pool, spa, 7 tons of central ac, washing machine, elec dryer, oven, kids blow drying their hair, chest freezer, refrigerator, water heater, etc.

the investment would mean that i would indeed be able to power a sealed room if i went LED. since i cant with DE's

Why not just dim the lights to 75%?

When you are running 18/6 for Veg dimm the lights down to 50%.

If you had the rooms on flipped schedules and simply dimmed the lights 50-75% that should account for enough amperage for going sealed & running A/C due to less power draw and less required BTU’s to cool.

Even with the lower wattage you would still great great quality/yields from going sealed with CO2 & A/C.

24'x24' room 16x 960w China bar lights in 5'x5' VS 29x china 480w qb288v2 boards in 3.5'x3.5'?

Which do you choose?

29x 480w "qb288v2" board lights (58x 240w board lights)

20x 650w bar lights

Keep the 16x 1000w DE's

16x 960w bar lights
