From DEs to LEDs

[420Barista]

eh i was hoping to halve my wattage yet remain the same yield and quality. if im only going to see a 10-20% electricity savings versus my current DE's i think i'll hold out for another year or two to upgrade.

I was a holdout when cobs hit and when I was finally ready Quantum Boards were here and I jumped on them. picked up 2 260watt kits which equal a hlg 600 and 2 135watt kits for veg this was b4 the smaller boards were out.

You'd be better of getting strips instead of boards. Strips give much better uniformity, which means you can hang the light a lot closer to the plants (say 8" instead of 18") and thus you lose a lot less light on the wall. Depending on the walls that can give 20% more light on the plants with strips from the same wattage (and less cost for the strips too).

And better canopy penetration if there's enough of them and they're spread out nicely. https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4559655/

So things here are going just great as always..

Over at the bat cave, its all about Totes and Trunks.. LEDS can grow trees!

At what distance from the canopy are you running the lights?

What up okie! I can see people get a little off topic on some of these threads. Lol

What is the diff between the qb120 and the qb228? Can i see some dry bud shots with a lighter for scale?

The amount of diodes which effect how many watts each board can run which effects having to run a heatsink or not. Qb120 has 120 diodes and doesnt need a heatsink but runs at 65-70w and a qb288 has 288 diodes and can run up to 150w+ but needs heatsink

@calitrees916 So annoying when people fill your thread with their thoughts..

Anyways-

This transition from DE to LEDs was one of the best moves i have made in my growing career. Here are some shots from my latest pull..

These had a 3 week flush.. Strain is Glurple #5 from Okie and Bean genetics.

Are your thoughts on the pics you just posted dominant over HPS?

No, about the same just with 40% less power.

Your using 20 percent less power and your A/C is cranking even harder? Thats honest and fair to say right?

why would his AC work harder when using less power?

Da fuk?

The same reason why when you used to grow your plants always looked burnt to a crisp. They run hot as fuck.

You really have no clue do you?
