Hi, Should I use the VEG lights 24x7 from the time I plant my seed until it's ready to bloom, or would something like 18 hours on and 6 hours off make more sense? Is there a "best practice" for veg lighting? It has worked for my first 3 grows. VIPARSPECTRA 600W LED Thanks, Mr.STM

Never grow at 24/0..............plants NEED "sleep" to have a correctly functioning metabolism. A plant with an incorrectly functioning metabolism will never be as healthy as it should be or grow to its full potential. 18/6 is best............24/0 is the biggest myth in the cannabis growing world.

Plants are living and like rest. They need 4 to 6 hours of dark a day. Plus it is a lot better on your equipment

18/6 is standard but its best to give the plant the maximum of 35-40DLI, this could look very different form 18/6 but playing around with the hang height and dim settings of the plant you should be able to achieve the result. For example. My lights only dim down to 40% and in order to hit a DLI of 37 I have to run them at 16/8 and in flower I will need to run them at 11/13 at 60% dim. If DLI is new to you google it. If you don't care to learn it judge how your plants are doing, they will let you know if its to much. DLI is easy to calculate when you know your lights PPFD values, most manufactures release PPFD maps on their product page. then google PPFD to DLI and a tool will pop up to calculate it. Good Luck!

18/6 is the most preferred time to veg. It allows a period of rest which people swear is beneficial for the plant and the soil. I know that it is clearly better on my equipment to not run 24/7 and my electric bill. I’ve notice ZERO difference in doing both times and finally decided on 18/6 was better for me.

Just keep 18h on and 6h off if you want to keep your girl safe. 24h/7 is just insane...

Amigo se você conseguir trabalhar 24h dia, 7 dias por semana? Tembai sua resposta Já experimentei varios ciclos, 24h, 20/4, 18/6, para mim sem dúvida 18/6 com os melhores resultados.
