What would be the best placement of 4 x80 boards in a 3x3 config?
I'm guessing a evenly spaced square.

How many boards for a 2x2 grow tent ?
Hlg120-c1400 with 2 boardsSo if I have this right I would select the driver for how many watts I want to run them ?
Slightly more expensive than plate.Are these gonna be less costly than a simple plate of aluminum, or is the selling point pre-drilled and tapped, and also lighter?
Series divides the voltage of the driver. While still giving the boards the same amperage.So a big ass thermal pad behind those boards on a decent heatsink should be good to 100 to 120w easy?
Still cant figure out how these run 3 or 4 boards off a single driver if they are 100v boards? What am i missing stephen?
hey robincnn,
i suggest to make them waterproof, so you can use them under the canopy, lighting the lower branches from bottom upwards. i think it makes sense to bring some light to the shadowier areas. way more beneficial than just adding more light to the fully lit top
Is there a benefit from series or parallel wiring on these? Is the difference between optics and no optics quantified?
These would work good for very low wattage cobs. Are they available yet? I'm planning on a 30 cob 300w light for a 4x4 area.
..300w from 30 emitters? Like, not even talking shit, but that's severely underdriven if you need 30 emitters for 300w. I get 241w from 3 emitters for a 4x2 area. Not to mention the cost of 30 emitters.These would work good for very low wattage cobs. Are they available yet? I'm planning on a 30 cob 300w light for a 4x4 area.
Im not so sure our plants want direct lighting from below.the leaf is designed to gather light from above and gather air/co2 from below.i guess i would. Need to see 2 clones side by side one with say 300w all from the top and one with 150w above and 150w below.in a vertical lite config the plant turns towards the light source and imo its not its natural state of growth and wastes some energy to conform to its environment and lighting.these plants are designed through evolution to grow upwards and spread out as they grow.just my take on bottom lightshey robincnn,
