3 way tie so far...seems like all but the 6000k are good choices? Interesting comment on the strains that don’t like above 4000k for vertical growth. That may not be a bad thing for my grow operation. I’m limited on height and want full width.

It kinda depends on how much you want them to stretch. 6500 will made the nodes the tightest. But I've been using 5000k because that's what I have.

I like to run MH and HPS in veg. I change the bulb depending on my needs and/or the needs of the plant. If/when they make affordable LEDs with adjustable spectrums, I may jump on board.

I have a couple of Durolux 200 watt 5000k LED's that I use for vege. They keep the nodes tight, but by playing with height they still grow upwards.
At flip they go under 3000-3500k Lm301b's with far red enhancements.
Nice and compact under the 5000's, most of the stuff from this stage gets pruned off anyways later on.

Who makes a good 5000k or 6500k LED for a 2x2' veg space? Would there be any difference between a 5000k grow light vs a 5000k garage light? same thing for 6500k...any difference between a "grow" light and a garage/utility light?

bridgelux vesta. tuneable 2 row strips w one row of 2700k and one row of 5000k. 90 cri. 2 ft strips are $10 each on digikey. they are a little less efficient than the eb gen 3 or lm301b but if you run them soft you can make up the difference. and u can either run each color on a seperate dimmable driver for super tuning, or just wire up your connections so u can easily disconnect one color (or use rocker switches etc). that gives you a light w 3 settings- 2700, 3850, 5000K.

I have one smaller 80W fixture im using in veg but about to add a few more strips to bump it to 150W and use it for full cycle grow and flower under it too.

@Rocket Soul has more experience w them and can add anything I missed.

Nope, its all there :)
I think the 3850K actually turns out to be around 3700k if you measure it with a meter.

One thing I learned on this forum is that 6k LED and 6k metal halide are not the same. I personally went with 4k LED.

I use 18 watt 6000k garage light strips for micro greens. Work great for that application.
