Huh?
I made that thread because I was seeing so much color change at my canopy but not any lower. Wanted to see if others have this same outcome.

What do you want me to contribute @OLD MOTHER SATIVA ?

I call these "Disco Boards".... lol
Here's a one channel Chinese board with uv, white, 660nm, 740nm diodes, only needs one driver.
2 x boards running at 130 wall watts.
Seems like they grow plants ok with nice par readings.

Kings Banner in foreground, Paradise Seeds Sensi Star original at rear.
Theyre in Biobizz soil, perlite and vermiculite. Tomatorite feed.
I warm the water a bit before feeding them due to cold temps in grow area.

Looking ok for 22 - 23°c - 71f lights on temperatures
and 7 - 8°c - 46f lights off temperatures.

Are these just Meiji boards? So are the middle diodes iR and that one line of green looking LEDs the UV? Is it only 400nm?

Hey guys, need some help.

Looking to cover a 4.5x2 ft space. Bought two blurple lights from Aliexpress and one of them has already failed just shy of the 2 month mark.

Got in touch with R2T and Meiju. R2T has quoted $228 (shipped) for - R2T QB288 V2plus 240watt 54V combo kit with Samsung LM301B & XPE 660nm.

Have a couple of questions before I finalise the order -

Is this kit suitable for a 4.5x2 space or should I be looking at boards with a wider footprint or at least with more spacing between the two boards? Also will be using the same boards for the entire grow, so should I go for 3000 or 3500K?

Thanks

Is it 2 x r2t qb288 boards on 240h driver?
What size is the fixture?
A single FOTOP 900mm x 300mm board from Meiju would be good for your space...... or 2 of them if you could squeeze them into your 2ft side would be the dogs ballicks! Lol

Use HLG if you're only getting 2 boards. Save the money to ship it here

It's a 590*205*20mm single fixture with 2 boards. Driver included is HLG-240H-54B + dimmer.

Can't post links yet - R2T-QB288-V2plus-240watt-54V-full_60828371558

Two 900's won't fit. Still waiting for a reply from the two Meiju reps I emailed.

Id go for 3 single boards on a hlg320 for that space for extra power and spread. The FoTop is great but a little shy on 4.5 feet. Better do it right. It also allows you to have different height cannopy which is nice.
