I went from hps to CMH's+Qb Led's
I like the mix because I can put 10k bulbs in a few of the CMH's for extra UV/blue the last 7-14 days.

I see the Viparspectra 900w only capable of 3x3 flower footprint, but trying to compare to 1000w hps that covers 5x5...
Looks like another version of Mars to me:oops:

Doesn't look bad bruh.. keep at it.

If you're ever trying to use the whole tent you're gonna need more light but if you're only doing a couple at a time you should be fine.

Plants look pretty good ...
keep canopy height between 18” / 15” ( both switches on. )

Also be aware that blurple plant feeding can be less than other lights.

Vipars WILL grow some decent bud , but not much good for multiple plants.
Your 900...... Actually pulls about 400 watts ... give or take.

I used them before and actually kept a 600 for laughs since moving on.
Grows WAY BETTER THAN MARS OR KIND.

They have similar complaints as Mars on the major sites like Amazon/Ebay.
Burned out diodes after only a few months.

I will agree they can grow good bud from the looks of it.
400w hps covers 3x3 aswell + the bulbs can be easily changed if they do fail.

3x3 @ "900w" equivalent vs 5x5 @1000W
Looks like similar claims as the other cheap M&M brand Leds

Can't post pics here anymore for some reason or I'd light it up long enough to get some, but I have a Mars 1st gen that only lasted 4 months b4 the first burnout diode. 1/3 of the diodes burned out completely b4 I quit using it for clones/veg.

Unlucky one of my mars reflectors has produced over 10 pound and its still 100% functional, safe to say i got my moneys worth

I had the CLASSIC white panel ... it did grow , but it was a heater ( hot running ) plus it burned out all of the IR diodes ... lens was black and melted. The overall build quality was laughable , but I managed to get a few runs done before sacrificing it for a DIY project .

Shitcanned original pcb board and threw a HLG quantum in it.
Life became better.

For the OP ... stay the course ... looking good . Let them run as long as they need , they will be done when they are done , not by time growing ....
Good luck ... keep us posted.

Bottom line ... it worked but obviously, plants would have been much better under better lights.
I will not lie I have seen some bomb ass looking flowers grown under blurple . Obviously the targeted chlorophyll A and B spectrum does grow a plant or two , and we all started growing with typical noob lights .... I managed to dial in the vipar pretty well ... that’s why I kept it.

The new light you made should stomp the orig.;-)
Same model I had with white panel + IR diodes burned out first yup.
