Cheaper to build it for sure. Depends on your comfort level with diy and if you wanna mess with sourcing parts. Buying a prebuilt is obv easier but you pay for that convenience

Check out ledgardener.com and search builds section.

I think a few f series or the new bxeb gen 3s strips on a 185 or 240w driver would rock that space.

If you can still get hold of 1ft gen2 bridgelux strips, as listed in the part numbers under bridgelux here
ledgardener.com

DIY LED Strip Build Designs for Samsung H-Series, F-Series, Q-Series, and Bridgelux EB Gen.2 - LED Gardener

DIY LED strip builds have become very popular recently. The mid-power section of our forum is full of threads created by DIYers looking to build their own custom lights, and new builds and ideas are surfacing every day. If you don’t live somewhere where you have easy access to premade lights...
ledgardener.com

Then it will be very cheap to build, you can even just use L or U aluminium profile for the heatsink as long as your driving them soft.

look up the part numbers and paste them into google and hopefully digikey or arrow still has them in stock for dirt cheap.
I think they are around $3 or £2 a piece.

A hlg120 driver would be plenty of power for your space.

Its enough height to do what u want. The link above would be a good option. What is the thinking behind the 3500k? You would be better off flowering with 2700k or even 3000k.

I was wondering the same thing. 3500k might be too much, but I'm a noob so am hoping to be educated. Best wishes

Bigger buds using a warmer spectrum. The only thing that I can think to use the 3500k was to keep em a liitle shorter for a small space. The more blues, the tighter the nodes. But I would train em short. Mainlining, scrog, lst, and opt for the 2700k and get the bigger buds.

Thats right. 3500k is more full spectrum. You said you were gonna use it for just bloom phase or flowering. I was just going off of that. If u are going to veg and flower in that cab, then I would get the 3500k.

Check out the Mars Hydro SP 150. 3.88K and perfect dimensions for that space. I have many different lights and out of all of them my SP 250 is top 3.

Good spread and as close as 12in away. I do 16 for better spread. I just love the spectrum and so do my plants. Side by side with an HLG 240 quantum board setup, the SP side just looks so much healthier. Less calmag def on the SP side. Looking at the plants in that color spectrum is so much more pleasing to the eyes also. 3000k was just looking so dull. I plan on buying a few more for my new flower room.

Mmmmm... Interesting. Thats a good distance for that. I gotta use the hlgs at 15+ inches. I grow in tight spaces so gotta be able to get close. Thanks!
