Yes, think this is the last winter for my HID's.

Did you equal the wattage for the heat?
For this winter I'll run my 750 DE in the other half of the room.

Waiting on PLC to get the new stock of their photo-boost strips to make my next fixture with.
Keeping my room cool during the warm months is more of a concern for me. 3 months use of a space heater cost me less than running a mini-split for 6 months of the year. My basement is conditioned like the rest of my home and I never had to use the mini-split at all this last summer running 750 watts of LEDs and 400 watts of MH.But if you replace with 500 or 600 watts will there be enough lights on heat?
I wanted to replace my 250 watt t-5’s in the 3x3 veg tent with an hlg 100 or build a 150 equivalent but I don’t think I can get the tent up to even 70 degrees even with the 4” exhaust fan on low.
Same problem in the flower room.
Now thats a handy little piece of information there. I havent used the hlg series mainly because they were a little harder to come by but its nice to know they can be overdriven.
Leds are very good man, love ‘em. You should post some pics too when its done :)
Don’t worry. I intend to document the process of building this light and it will be shared here.
Ok as promised I finished the light and documented the process. The unit is 44"x18" with 4 HLG 132 boards running off a Meanwell HLG 240H-C1750B driver. The power draw ranges from 8w up to 240w. The build was pretty simple but took a bit of time to get everything laid out as I wanted it.View attachment 849481The first step in the process was laying out a guide for the tent size and center line to determine how to most efficiently spread the pannels.

The layout that seemed to most effiently be mounted and spread the light evenly.

All the rails cut to size and parts available to be connected.

The outer frame is assembled but the cross bars (that double as heat sinks) are still free floating. The boards are simply placed on to determine real spacing.

Cross bars are attached and once more a center line is determined to ensure a symmetrical light pattern.

Boards are attached.

Wiring of the boards. They were done in series so if there is a failure the whole unit will turn off rather than overpowering the other boards.

Potentiometer attached to driver. I know the connectins are still exposed, I still need to build a small housing for the dimmer. I left those connections exposed incase I want to extend the line so the dimmer itself is outisde of my tent.

Driver is wired to the light. I used a 14 gague cable with a heavy duty plug, which should all be more than sufficient for the power being drawn.

All plugged in and runing great. There is vurtually no heat coming from this unit, I can touch any and all pieces even after running for 17 straight hours.

And finally, babies in their new home.
Very nice fixture. Congratulations. Virtually no shady spots and great distribution overall. Qbs and strips are very cool for sure. Tho cobs are cheaper and gets the job done, if i had the budget i would go with qbs too. Waiting to hear about your monster yields now :)
Damn Midwest you are just killing it with your setup. Nice work man.:smoking:
I looked into cobs and it was absolutely cheaper to make this build. With all parts and tools it cost me a little under $300 USD to build this light. In all the places I looked it would have cost me between $60 and $100 more for a cob build of equal wattage. But what really matters is that I am super excited to really get into the grow to see what this light can really do.
That’s a rock solid setup bro. I love it!
Which one tho @MidwestToker @Smoking Gun or any other :D
I think they’re all great including mine hahah.
If you run 3k across the board it's basically a flowering light. The challenge is as you say keeping internode length ideal.Useful info here. The idea between option 4 is that i am having some issues with vertical space at the moment with 3000K. I actually completely ran out of space. Besides that there are no real reason to go with the option 4.
I know people prefer higher reds in flowering. But also there are some people who swear by the blues. Now things are inconclusive on my end.
I am growing 2 strains, 4 plants. All from 2 mothers which i have grown in my last grow. Under blurples supplemented with 6000K bulbs.
The inconclusive part about it is this.
NL’s did way better under 6000K and blurple. Frostier with more terpenes and fatter for sure but it as also getting good feedings which it doesn’t get this time cause i am doing an only water grow.
Dinachem’s are doing better under 3000K. Frostier and fatter for sure. But in the first run i fed it a bit much, especially with some enzym teas and stuff so it was stunted in early veg thru early bloom. This time it seems like it loves the only water thing. So thats inconclusive too.
