Looks great
10weeks and you are going how much longer?
Is this a clone run?
How many watts?
Im vegging under one of my 50w claimed COB screwins
They seem to like it

Those are 15w bulbs (180w) over 6sqft (30w /sqft). As you can tell by the airspace, I was expecting a bit more stretch, but they don’t care - plenty of penetration with the screw ins. All of the plants are from seed and seeing as these are the more squat plants of the cross, figure 12-14 weeks total before they finish.

That's a sweet little setup ya got there Terp. How much dry weight do you think you'll harvest on this run. Really nice job!
So I’ve decided I’ll buy a scale just to answer questions like these
Realistically, it’s at least a quarter gallon mason jar each plant, which in my experience are 2oz a jar - so minimum 1gpw.
I’d expect I’ll end at 4.5-5 jars, so probably closer to 1.5gpw / 9.5-10.5oz.

Why do screw ins have CRI color rendering index and when ya go big led this isn't mentioned? Or is it mentioned w certain brands of LEDs. I'm beginning to think for my grow room a combination of the sf4000 and screw ins ( ya know I love those feits) ..would be ideal.

Samsung lm301b diodes come in a few different cri's, just depends on the manufacturer, which version they decide to use: https://www.samsung.com/led/lighting/mid-power-leds/3030-leds/lm301b/
A good LED manufacturer will tell you the specs on the LEDs they use in their fixtures.

Blynx...
sorry, I was going to do some kind of crazy post that showed I was hip ... But WTF...
I never really saw an answer in this thread from you.
How often did you water those 3 gallon tote/pots? I am using "sub irrigation(a sub soil reservoir)" in a 7 gallon pot, with maybe 5 gallons total soil and a 1.5 gal reservoir.
I give 1 gallon every 4 days.

I would estimate maybe a gallon a week during full flower.
I water the micro cabs using an old 32oz Powerade bottle. I usually give it one or two of those every 3 or 4 days.

Thanks for the response. I will say again that your microcab grows and this thread are what inspired me.
Here is my current sensi seed Northern Lights about three or four weeks before chop(not sure yet how much I slowed her growth earlier in flower. I roughed her up quite a bit about week 3) under just over a hundred watts of SIL.

These aren’t the most efficient SIL’s t 17.5w each for 1600lm.... but the CRI is 90 which I feel like does something great... I dunno much about it all other then these FIET brand bulbs grow some freaking sweet sexy buds for me and I have 72 or more
Of them on hand so I’ll probably use them until they die... constructive criticism welcome.
5 - 1gal GG girls under 8 x17.5w fiet electric 5000k at 5wk and 6 days lower
Same girls 7 or 8 days later
