My interest is peaked. Is there good info on COBS on this site? Didn't Heisen post a pic with some cobs on a rail recently?
I would recommend going with the quantum boards. COBs are great but they're just more expensive. The quantum boards are just as good or better and less money. Especially if you use boards that don't require heatsinks like the QB120s or QB132s. They are so incredibly easy to put together with the drivers. No soldering required.
They have the QB132s and the QB120s for sale on Amazon in packs of four. The QB120s are around $125 for a four pack and the qb132 are $133 for a four pack. Four of them will flower a 2 x 4 area. Four of the QB132s can be run on the LRS-350-36 driver, which only costs $30. For a 2 x 4 area you are looking at $133 for the boards, $30 for the driver, and $20 for wiring. That is $183 to flower a 2x4 area, plus all the electricity savings.
If you want any help matching drivers with boards just let me know.
Anyway, sorry to go off topic on this thread. Back to Greenpoint seeds. Getting ready to run Bodega Bubblegum and Garlix. Can't wait to see what pops up.
Damn I wish I hadn't missed out on the wedding cake.
Edit: I had the cost calculated wrong. It's way cheaper than I had before.
