Indeed you can use green lights if needed to interrupt the dark cycle of a plant. This should be done on more of an as-needed basis than regularly as I’ve heard compelling arguments that plants do indeed process the green light though much less rapidly or intensely than red or blue.
I would also point out that some “green” lights are simply white lights with a green-tinted cover on them. The light to use would be a green led headlight. I use this one as needed for pre-dawn foliar feeding, or to switch laundry during the night cycle at a former house!
Whether you’re growing your cannabis indoors our outdoor in the Colorado sun, from a clone or from seed, it’s all about the light, so make sure you’re as informed and careful as possible. – Absolute Summit
