I do not believe Medic Grow uses the better Samsung diodes. Please check.

Very nice. Know if new boards fit on QB288 triple heat sinks ?

Nice plants. What level of PPFD do you have at mid plant adjacent to side lights ?

I like more 660nm red than vipar offers on spectrum especially for flower.

what ppfd level running ? Normally 50 or so watts enough for those early plants

my bad....thought you said 1800 .....too much planet of the grapes !

shooting up once a day ok also ??

$ 2.04 per watt pricey light, what extra getting for almost double cost vs, others ?

still week in corners. better off with mars fc4800 (cranked down) bar light very even ppfd across the board. Or any other bar lights. just a thought.

like to add some azomite and lime also.

these ?

I run Mars FC4800 and HLG UV supplement in 3x3. Just have to crank down some.

Could use more 660nm red in spectrum.

Kind of weak for being into flower ?? usually 700-900 range.

nice plants. like that evo light so far? about transplant time.

Know what type of Top bin LED's are in the Progrow1800 ? Cant seem to find. Nice par map. Like the 660nm spike. Little low on blue...??

This light lacks the heavier red 660nm in spectrum...... sure will flower OK, but there are many other choices.

that what they do put new cover and edition for more sales.

MARS FC series / spider farm cheaper lights have more red. Not necessarily HLG. Thanks
