answered grow question 6y ago
About 18 to 20 inches. The lights are very bright. If leaves start turning yellow on top it is too close. But I would go 20 inches if they are still stretching. Will have to adjust regularly. Good luck and enjoy the harvest. Happy growing 🌲🌲🌲👊

Should I use Blue light switch or Red light switch or both for vegetative growth?
I'm currently using a Giixer 1000W LED grow light. The lamp has two switches. One for "blue" light ay 450nm and one for "red" at 600-700nm. I am currently in week one of the vegetative stage. I have both switches on for "full spectrum" lighting. Blue or Red switch alone?

Wow. Thank you so much for the reply. I have been playing with LUX meter app and my light. I was bit skeptical about the lumens that I would get from the 15W but as it turns out, it receives well enough ppfd. Still skeptical about the spectrum i am having.

Best LEDs or small HID to replace 1000W dimmable HID for small space
I'm using a 1000w HID setup I had from before, running at 50% in a cool tube. It's loud and not efficient. Maybe it's time I switch to LEDs or a 250 HID. I don't want to sacrifice bud quality but I'm low on funds. Any recommendations for a good light that will fill this space?

LIGHT SPECTRUM, is that a good one for growing cannabis?
Hi guys, in the future I plan to upgrade from the current 2x2 box/150w LED. I was thinking of a 4x4 area with 500w LED. I came across an interesting 500w led lamp for quality/price and this is the spectrum chart, does it seem suitable for growing cannabis?

Did I start LST too early?
At day 22, did I start LST too early? I feel that I may have stunted the growth a little from overheating, but didn't want to wait too long to start training. Also, would a higher-powered light cause less distance between the nodes, and therefore make LST harder/less effective?

variable Lichtzyklen bei Autoflowers?
Idee für nächsten Grow. Hat jemand schon mal versucht bei Autoflower die Lichtzyklen anzupassen um die Pflanze auf voller Leistung zu fahren? Meine Idee ist die Beleuchtung während des Grow anzupassen auf: Seedling 24/0, Veg-Phase 18/6 und späte Blüte 12/12. Input? Erfahrungen?
