Hi,

Im putting together a shopping list for my DIY COB setup and I need some input, I want to Mix MH + LED for my veg stage and HID + LED for the flower stage like in my sketch below.
Running the 2700k LEDs during veg should make the outer part of the plants stretch to fill up the canopy while the sweetspot under the 400 or 600W MH should get plenty of light and stretch less.
During flower the 2700K led should supplement the HIDs not so great red spectre in addition to give the outer parts direct light above to stretch for.

I will only be doing 2-3plant scrog in a 4x8 or 5x8 tent.

- Anyone have some comments on buying from kingbrite? how is their prices?
- What BIN should the COBs be? CRI? is he top bins worth the extra cost? (BIN, is that like batch? top batch?)
- I wanted to mix in some 6500K COBs that I would run during flower, but it will cost and Im not sure if I really need it?
- Comments on my sketch below? is there enough light for a 5x8tent? What about the spacing with regards to the light?
- What about heat from the HIDs, are they too close to the passive PinFins?


Shopping list;
8 x CXB3590 2700K
2 x MW driver HLG-185H-C1400B
8 x 80degree Glass lenses (for better protection of the COB) Comments?
8 x Passvie PinFin F133*70mm Comments?
