Danke für die Antworten. Ich werde sie aus Zeitgründen in ihrem Zuhause belassen... aber gut für den nächsten grow... Wenn ich auf 12/12 umstelle soll ich dann auch gleich die Lampe wechseln?🤔

Hi! Yes the grow area is pretty full horizontally so yes you should flip the switch now and you might have to do some lollipopping later on in flower

pH very low (5.0) but plants seem to appreciate it!!
The pH of the reservoir is lower than the perfect range (5.0) during flowering stage for almost 2 weeks but plants don't seem to suffer. They are growing very fast. Should I change it or leave it if they seem good?

HLG UVA supplement
Introduced this hlg 30 uva light as a supplement to the twin 260s. I've read just 3 hours a day increasing 1 hour per week up to 4-6 hours before harvest. Anyone recommend anything differently or just run it 18/6 with the lights?

And if it's not difficult, tell me how I should control the light at all stages of growth from growth to the end of flowering!? at what distance from the plants should the light be? and what power adjustments on the driver should I make?

Which strategy with auxiliary grow Leds ? 3x20w Leds -Thanks !
Helps maturing but I wonder if buds are bigger. I used to put 3 extra lights 20 cm below canopy, leave many large leaves at the top and lollypop 30%. 30% is definitely not enough even with those 20w LEDS (50% is probably better). How do you use extra LEDS ? Where do you put them?

Can you make an Auto flower by changing the light schedule?
Ok, before everyone jumps on this with the obvious answer - I understand that you don’t NEED to change the lighting for an auto to flower, but my question is can you, if you wanted to, flip an auto to flower by changing the light schedule to 12/12?

Review this model or help me create a DIY COB plus IR plus UVB grow light.
I've very limited variety of lights in this country so this is all I can find. Also there are no suppliers who provide spectrum charts or any temperature values for those lights. My goal is to make it with the best possible light spectrum. Having IR's also will help on cold days.

Too early to turn up the dimmible LED light on my seedling?
Unsure if it's too early to turn my light up just yet or wait till more leaves are growing. Currently at 25% (10,000 lux aprox.) using the dimmer for a 120w LED at 20 inches from seedling. Thanks in advance.

Use lamp while waiting the sun ?
Would it be worth it for me to go and buy a CFL bulb at a DIY store while I wait for the sun to come back? Or is it not good to have 2 different types of lighting (sun and cfl bulb)? And what kind of cfl bulb I could take?

additional blurple lights
I also got the blurple lights from my friend. To keep the temperature down I haven't installed them yet and not sure if I will. Will they make a difference if I add them next to the current LED? If so should I wait until the flowering stage or anything like that?

ViparSpectra XS 1000 (x2) vs. HLG 100 RSpec (x2)
Thoughts on VS XS 1000 (x2) vs. me buying HLG 100 RSpec (x2)? They'd go to either side of my HLG 225 in a tent that's 2.75' deep and 5' wide to 'fill the wings' more evenly. Thoughts on build, safety, quality & heat? HLG 100RSpec:0 / XS1000: (on sale this weekend)

Power and distance
Ok so...... This is a Mars Hydro TSW2000 specific question. 1, When should i go 100% with the light as far as plant age is concerned? 2, I've seen various distance tables that all vary so i'm asking TSW2000 growers specifically what their distances are for Autos. Many thanks
