it looks like the F8-PLUS is lm301b/h diodes with added 660nm, the F8-MAX has added 660nm 395nm 730nm diodes

im sure i can build something to raise/lower the lights. although i certainly dont plan on using those cheap light ratchet cords, that would be a nightmare

ill be using 90cri chips, if i need more red on top of that ill supplement using something better than 660nm epistars

ill be running 19x 600w in a 4 ton room. lets hope its enough lol. by my calcs it should be. 600w/.94/.96=664w 664x19=12616w x3.42 = 43146 btu

Im almost done with this buildout. I kept the 1kw DE's and actually added 2 more for a total of 18x lights in roughly 4.5'x4.5' squares. i sealed the room and installed 2x 4 ton mini-splits that will still pump heat out down to -22f outside temps. finishing up building the SCROG frames, gotta...

i will be contacting airgas or a co2 supplier nearby that fills the large tanks for local breweries. i think they will rent out the big 200-500lb tanks. first i want to run my room without co2 for a few runs to see how she produces without co2

lol i havent started the basement yet. currently trying to button up my garage build out. I'll be starting the basement in a few weeks. currently working 50+ hrs a week at my day job and only have time to work on building out my rooms after work and weekends. plus im kind of lazy so its getting...

Looks like im about 90% sure im going with 19x Meijiu F8 600w Bar lights in 4x4 pattern. they’ll be custom using all 90cri LM301b 3000k diodes, no additional 660nm or far reds. Meijiu has 3 main types of bar lights now. the MAJO (angled reflector bar/heatsinks, 256 diodes per bar), A8 style (has...

its actually 19x not 20x heres the floor plan though

Latest quote for custom bar light 90 cri 3000k lm301b diodes and inventronics 600w driver A8 483.00 ea. F8 512.00 ea shipping for the A8 is 1500.00 shipping for the F8 is 2100.00 by sea ddp

It's not built yet. I only.have my cad file of the floor plan lol.

Did you get 2x A8's for 1250 shipped or the F8's?

i was quoted "A8 also can make customized (90cri lm301b 3000k), total cost for 20x kits USD12839.00 DDP ship by sea to your address tax included" -Rita which comes in about 642.00 ea shipped

Thats what i was scared of. im gonna see what the cost if from Meijiu after sea shipping DDP to my door for 20x A8 or 20x F8

I think that F8 is the way to go! i might get a quote for that F8 running 100% 90cri LM301b 3000k diodes

is that inventronics driver 0-10v controllable?

A8: 8pcs High efficiency led grow strip(Total 2048pcs LM 301b+64pcs IR 660nm) (bottom pic) F8 i cant find numbers but the F8 appears to have 400+ more diodes total (top pic)

they might be i wonder if shipping is reduced though depending on how each light breaks down into its shipping box.

the kingbrite has 1280 total diodes in a 5 bar config the Meijiu A8 has 2048 total diodes in an 8 bar config. if they are both running a 600w driver id go for the most diodes for the softest driven watt per diode numbers.

I think they have 3 main bar light designs right now. the A8 (fixed bars) the F8 (folds in half) and the MAJO (curved reflector bars). they all come in various bar counts using various driver configs. im interested in seeing which version from them comes in cheapest for an 8x bar style using...
