HLG 240H 24B powering 9 or 10 LMC561c strips

Then you shouldn't need more than 1.2ec max for nutrients

Post 270- those never saw temps above 76 degrees and never cared about VPD, dehuey set at 50-60% full run

Are you adding Co2 to your grow ?

I get 268 draw watts from my HLG 240-B drivers

Do you have a dimming pot on the driver ?

66, been here at riu since 2010

9 ltr pots, fed 2ltr's once a day, to run-off once a week

Even in full flower my coir gets no more than 1.4 ec max and I never feed more than once a day, pot size to plant size will always determine feeding schedule

Oh, most failures with new growers comes from overwatering, over nutrient use or too much lighting for their plants size, why throw another variable at them until they have the basics down making them think that all the problems are coming from VPD ? VPD out of range is not the most common...

Same spot

Something wrong with these never paid attention to VPD plants, grown under LED's ?

Cannabis specific Nute's? I guess farmers use specific nute's on all their crops they grow now ? ridiculous,

Do you have side by side comparisons of plants grown under prefect VPD vs non VDP plants ?
