LED Kelvin Temp 3000k-6500k
m0usestarted grow question 5 years ago
Is there a massive difference in colour temperature/kelvin of LED's if the lumens, PAR, watts, intensity and every other aspect you can think of is the same but its temp/kelvin is lower? I use a 6500k LEDs, may mix in or switch to 3000K for better flowers if its proven to work.

Hey @m0use!
I recommend at least 3500K-4000K for flowering. You will notice a big big difference, you will start feeling the difference when they start stretching up. And finally, as they will be more warm, you will notice on the size on the buds on next weeks!
You can still use your 6500K LEDS while combining with 3000K-2500K LEDs. You will improve your spectrum.

The lower color temps are better for flower, for sure.
6500 is near bright/sun light

6500K contains more blue so mostly goog for vegetative stage and not recommended for flowering . 3000k is more red/orange so it's bette for flowering but you can still achieve a veg under it . If you can then buy a 3500K as it's good for both veg and flo or you can go with a MarsHydro new quantum board or the SpiderFarmers which have both a specific and eficient spectrum

What is shelf life of silver thiosulfate ("STS") in practice?I know it is recommended to use within 30days of mixing final solution.
However, what "works" can often be different from the recommendations. Has anyone used an STS solution they made after 2months? 6 months? How did it go?Other. General questions

F44: dozens of gnats stucked on buds & sugar leavesHey,
I noticed dozens of gnats stucked on sugar leaves and buds trichomes/resin... I tried to pick them by hand but there are too many.
I saw articles about bud washing which seems to be a good thing except for higher mold risk.
Would it be the only way to smoke bug free weed?

Lighting cycle for VEG stage. Is 24x7 OK?Hi,
Should I use the VEG lights 24x7 from the time I plant my seed until it's ready to bloom, or would something like 18 hours on and 6 hours off make more sense? Is there a "best practice" for veg lighting? It has worked for my first 3 grows. VIPARSPECTRA 600W LED
Thanks,

Flushing with RO Water (EC 0,0) or tap water (EC 0,8)?Hi.
I think, it's 1,5-2 weeks before they are ready to harvest.
Tell me, if you see something else in the pics. :)
I want to flush them now every 2 days with only water.
I have the opportunity of RO Water (EC 0,0).
Should i use the RO water or normal tap water (EC 0,8)?

Bad idea?Will a mars hydro TS1000 be too strong for a 60x60x140cm tent?
I have been using a TS600 and TS1000 in tandem in a tent 4x too big for the light level, I have been growing strong and tasty buds but with low yields so downsizing my tent size to maximise the light.Other. General questions

Should I harvest in 2-3 weeks ?Hey, do you think my plants might be ready in two weeks ? They're autos in 7th week of their life. I know that 9 weeks is ok for most, but these should take approx. 11 weeks. Do you think one more week of feeding, then flush would be appropriate ? Trichomes are mostly milky white

77 days old autoflower, up to this point is personal taste or still there ways to go?
I majorly see milky and a few ambers trichomes, correct?
Those white pistils are due to the foxtailing, so is not a good metric.
