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...

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...

MindSoup Posted June 17 Author Share Posted June 17 , interesting results though, looks like the apps can be more or less as accurate with the right phone. 1 Link to comment Share on other sites More sharing options...

My partner was deciding between an iphone and android a couple of years ago. I was trying to convince her to go for android, she didn't. Needless to say after the photone app came out I've been using it on her phone, and I am less partial Edited June 17 by Lubdub 1 Link to comment Share on other sites More sharing options...

Military Grade Posted June 17 Share Posted June 17 (edited) My phone was out by 1% compared the the light sensor that tested my light in the Migro video about my light Got lucky with my phone Edited June 17 by Military Grade Link to comment Share on other sites More sharing options...
Slippy One Posted August 10 Share Posted August 10 I’m putting this pic here in case anyone wonders what PAR reading you can get at 15:30 during August in direct sun. I’ll post another one at midday on Monday where we’re expecting 33°C. 1708.5 PAR which would most likely damage plants using high powered LED. 2 Link to comment Share on other sites More sharing options...
Military Grade Posted August 10 Share Posted August 10 I dabbled at this a few months back, just over 1000 with the sun out in direct sun light, when a clouds get in the way it drops like a stone to around 100, this is probably why DLI and high ppfd don't have negative effect like indoors due to the interruptions of the clouds. 1 Link to comment Share on other sites More sharing options...
Slippy One Posted August 10 Share Posted August 10 PAR is spectrum sensitive isn't it? So it doesn't take into account the IR & UVB the sun omits? 2 Link to comment Share on other sites More sharing options...
