Hello,
newbie with a quick question here.
Im starting my first budget grow (4x4)
I really want to go down the LED path instead of HPS.
After some research I will probably buy the
"HLG 550 V3 480W Samsung LM301H LED Grow Light" from Kingbrite
What Option do you guys recommend?
2700K
3000K
3500K
4000K
Since im a beginner I will grow autos so maybe 3000K or 3500K?

3000k. Start to finish.
Or you could check out the bava board I posted.
I haven’t got mine yet but it looks ideal. I’m going to use two for autos in my vegetative tent.
I’ll post a review once I run them.

I’ve got the Majo 800’s up and running. 12/12 flower time!

Bright as hell! Will review soon.

No idea on those, the write up seems a bit fake, i do not believe 3.03 ppf/w system level, especially with no reference to what diodes used and the very cheap price.
Usually when they say IR they mean far red 730nm.

Yea 730nm is the ir... I have the light and that is what I paid for it... Sight and vendor are legit... I was more curious if anybody has used the 301h samsung diodes yet? If they saw any diff from the 301b? I have a couple qbs (just learning about leds, been an HD guy) but my other two are 3000k 301b +660nm no added 730 or 240(I think the uv is 240?) I just asked suplyer about what diodes wer used... Waiting for a response they are usualy quick to reply...

I think it would be a little early for anyone using the 301h diodes to pass any meaningful verdict to be honest.

Its going to grow nice, its just hard to say anything from the info they give and i think youre the first one here to try one. With china the diode could be anything but usually its it good enough.

UVA is usually used. 385nm ish. I could be wrong for your specific brand. LG is used a lot for uv.

I've got a question for those who know. I'm trying to help a friend build a 2x4 tent on a shoe string budget. I had a spare 2x4 tent and some extra ebb & flow buckets(shopping for a brain on craigslist), so we're already close. We got to talking about lighting last night, and I mentioned the options that Bava and Meijiu have. When looking at the Meijiu lights, I noticed that they offer lights with LM301B supplemented with Epistar 660 NM deep red.

My question is about the deep red. I believe HLG uses Osram for their deep red. Is there a major difference in efficiency or output between the Osram and Epistar deep reds? Would he be better off just getting a board with just Samsung diodes, as opposed to going with one with the supplemental Epistars?

I believe Osram is better.

Meijiu also has a Lm301b with Osram 660 and 730 and LG 385.

They’re new. For a 2 x 4 grab a 240 watt board.

I just started running a Meijiu Lm301b with 660nm epistar and beside that a Lm301b with Osram 660 and 730 and LG 385 a week ago.

These are Bava 240 watt I just got.

2700/4000k Lm301b with LG385nm and Osram 660/730nm. UV on/off and dimmer. Nice board.

They’re on for $185 plus shipping right now.

One of these would be perfect full cycle for your 2x4.

Having trouble finding this. Do you happen to have a link? And a link to the Meijiu with Osrams too, if it's not too much to ask? I honestly couldn't find either.
