I do. if my vegging plants are at 500 PAR, when I go to pre-flower, I set to 700 PAR for the stretch, then up again to 950/1000 PAR for flower proper [its still experimental atm, cos my LED's are still new/at start of learning curve] mystic 1 Link to comment Share on other sites More sharing options...

Anyway, thanks for the info, good to know what plants prefer without the usual slagging match we hardly ever see these days.. It was on the same page, just needed to scroll up, I feel your pain, can be a pita sometimes changing pages Edited June 13, 2023 by The Villan Link to comment Share on other sites More sharing options...
MindSoup Posted June 13, 2023 Author Share Posted June 13, 2023 10 minutes ago, mysticriver said: do you increase for pre-flower brother? For the most part I just let them grow into the light, 300 will be 600 once they get taller and then a few days into stretch they'll be into the 750. Definitely not the most energy efficient method but any way I can save lifting a finger and all that . Link to comment Share on other sites More sharing options...
catweazle1 Posted June 13, 2023 Share Posted June 13, 2023 Multiply by 0.017 for PAR level. Set the height you want, sually 6" or 12", or whatever and adjust the intensity at the control to suit the growth stage, and maintain that par reading for that growth stage. You can lift the light as well to dim. The greater the distance, the more energy you need. Do note I'm assuming the fixture ENTIRELY covers the grow, or near enough. If the light is compact in area then you have to work with a higher fixture to get the required coverage to the edges. Link to comment Share on other sites More sharing options...
