Thanks.They are looking good man! The light does seem to be working well.
Once I mix and pH a reservoir, I don't even bother checking it again unless I top it up. Also, I am lazy.
That's for drain-to-waste Coco Perlite mix, just add nutes to RO water and pH to 5.8, very simple.
In a recirculating system I might check it more, but probably not.
Is the spectrum for your Spydr 600 still the same one you listed a few pages back in this thread? This one http://www.bmlcustom.com/custom-report-details/?partNo=PS3690S101GEAGSEGAGESGAEG ? If so, are you happy with it? Would you change the spectrum in any way?Rez change day
Buds sort of easing along the last few days, a sign that nutes are expended, even though ppm is high
SPYDR 600
Reduced to 700ppm

Half of the custom COB system will be here soon, I'm pretty excited.Thanks.
What did you wind up doing for lights?
Recirculating Rez changes the game
As the ladies build buds they dump serious waste products, which in my case are going right back into a ~ 3g rez.
It would only take 3 days of not readjusting for plants to develop mysterious issues

I have been considering using the Spydr 600 as side lighting along with a Rocket Plasma and I am trying to figure out a good sun like spectrum using mostly white leds (for a more balanced spectrum) but heavier on the orange and red side for flowering. I would like to use it through the vegetative and flowering phase like you are doing. It seems like we would want to imitate the late summer outdoor spectrum for something like this but that is just a guess. I am definitely not an expert on the subject.
I must say that the "Custom LED Strip" website that BML has is pretty sweet, I have been playing around with led combos for almost 2 days now but. I stumbled across this grow comparison today by Greengenes between an Apache Tech AT600 led and a 1000 watt HPS https://www.rollitup.org/t/apache-at600-led-vs-1000w-hps-blue-dream-grow.813412/page-40 where the guy achieved a .96 gram/watt. So I think that I will try and mimic the AT600 spectrum for my Spydr 600 (if I choose to get one) build since there are proven results with the spectrum. ( At600 vs HPS 1000 grow video hereIt would appear so. Somehow I thought I had mixed ~ 90% 2700 + 3000, which was one of the iterations I toyed with. The 625s was BMLs choice, and a good one. The only reason I thought to mix 2700 & 3000 was I was unclear as to their spectral graphs at the time.
3000 + ~ 10% @ 625 would be very nice for flowering
Keep in mind I chose these spectrums as a veg AND bloom light
If only for flowering, I would go with 80% 3000 + 10% @ 625 + 10% @ 3500-4000 these to make sure there is sufficient blue throughout flowering
In a pinch you could likely veg pretty well with this too
Hey Pet - I was under the impression that the 3000k 3070's were putting out a decent amount of light around the 625-630nm and that supplementing with additional 660nm was the winning ticket....What do you think?
The mix you suggested of 3000k, 5000k, & 625 looks good. A CRI of 95 and more similar to the sun than the spectrum I posted in my last post. The micromoles are a little lower than the last spectrum but. I would rather have it more like the sun than anything I think. Copying nature would seem to be the smartest move when it comes to this stuff imo. I split them up more like 3000k @ 60%, 5000k @ 20%, & 625 @ 20% though http://www.bmlcustom.com/custom-report-details/?partNo=PS3690S101GGCSGGGCSGGGCSG . I think this spectrum would work well for me since I would have the plasma for veg and come flower time I can cut the Spydr on to light up the sides for flowering.GG707 is an excellent grower. I follow him closely. And AT makes excellent products
Keep in mind companies design panels well ahead of the quantum level improvements being made in white leds on a daily basis, or so it seems. So ATs blend choices then will probably not be the same as their next gen
Today, Cree has COBs (several guys here using them in DIYs) that are damn near perfect for mj from seed- harvest- but they are $$$$$$, and point source. I prefer an even light distribution across the canopy
As I mentioned above (but slightly revised here), were I to select diodes today for my SPYDR, I would go with ~ 80% 3000 + 10% @ 625. The other 10%, I would replace the 6500Ks with 5000Ks.
This should make for a complete light for veg-harvest
hth
and please mention me, should you order
