Bulb identification
TreeHufferstarted grow question 3 years ago
Need help trying to figure out what size hps bulb i got with a used 600w apollo digital ballast.
It has no markings and i suspect its a Kw bulb based on size and shape. See pics.
Appears to operate fine even when ballast is turned down to 50%(300w).

If you plugged it into a 1000 watt ballast on full blast and it didn't blow the light, then it's a 1000watt bulb. A 1000 what light will also fire with a 600 watt ballast, but a 600 watt light will not work in a 1000 watt ballast on full wattage with bursting, but it will run in a 1000 watt ballast dimmed down to 600 watts

Best Light Schedule for Autoflowers?I'm wondering what light schedules my fellow growers like to use with their Autoflowers? I'm debating weather the additional cost of a 20/4 is worth it in terms of growth and increased Bud Quality/Size over a 18/6 schedule. I would love to hear your experiences.Setup. Lighting

Lifespan of led grow lights?Lifespan of LED quantum boards?
Hi
I'm looking for anyone who has first hand experience with the lifespan of the led grow lights. I'm not looking for the manufacturer guidelines. Just anyone who has noticed any difference in performance from the LEDs over time..

When to lower light intensity?When is the right time to lower light intensity? I'm on 5th week of flowering, should I keep my lights on max or reduce the power/increase the distance to plants? I have around 1000W of Led's at 35-60cm distance from the tops. I see no burning/bleaching or anything like that.

'Claws' on tips just after flowering started. Previous answers help - it is a bit worse. I keep a perfect VPD. What should I do? Flower wouldnt fI'm confused. For the first 3w I used LED as instructed 30-40cm, I had ~43cm,100%dim, everything was fine. When the bloom started yellow claws appeared and still there, maybe a bit worse, with 53cm and 75%dim. Mostly on BPP, one more plant showed her claws today aswell. 😓

What lights for a 2'x3'x6' tent?What light or lights for a 2x3 footprint? Veg and flower. Deciding between 2x Viparspectra XS 1500, 2x HLG RSpec 100, or a combo 1 of each. Budget is 200-300ish. Cheaper is better. Open to suggestions. Not sure if I should have 2 of the same lights or mix n match.
