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..

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

How much light - PPFD - without CO2?How high in power should I go with my lights without CO2 enrichment? I can comfortably provide 1200 PPFD to the canopy, but I'm holding it down near 900 because I'm not sure the extra power used would yield an increase in, um, yield.Week 7

Switching light schedule for an auto and Phototype!I'am growing together an auto and a phototype with 20/4 light circle. For my phototype is about time to change light schedule for flowering, will my auto be badly impacted by switching to a 12/12 light? Or should I move every day (same place but no light) the photo for the night?Setup. Lighting

Light height full power vs dimmedHi, with light height, does it make a difference to the plant if I'm at full brightness and further away vs dimmed and closer? I'm going to start running out of tent space soon so I'm expecting I'll need to dim in late flower. I think it's ok just looking for assurance :)Week 6

Lamp distance from seedlings? PPFD uploaded in this weeks photos.How far away I should have my lamp from my week old seedlings? I think it has something to do with the PPFD for my lamp (TS600), but I have no idea what it means. The lamp is set right at the very top of my tent now and is 32 inches (81cm) away. See photos in week 1.Setup. Lighting

Autoflower 24hrs of light?AUTOFLOWER - I checked on my seedlings this morning, and the temp in the tent dropped to 9 degrees celsius during the night. My light puts off a bit of heat. Am I better to run the light 24hrs and maintain a warmer temp, or give them a few hrs of darkness and risk dropping temp?6y ago

When to flip LED's 'bloom' switch on?When's the best time to flip the 'bloom' switch on my LED with an auto?
Should it be at the first sign of pistils or is there a better time to do so?
I have already flipped the switch for this plant and kept photo-period the same, looking for info for next grow.
Thanks!Week 7

regarding the light spectrum ratio. what is the ideal light spectrum for both the vegetative and flowering phases?
Do you use 3500K lights during the vegetative stage, or only use cold white lights at 6000K? do you then switch in flower to 3500K lights along with 370-780nm?Setup. Lighting
