    Seedling PPFD?

    Posted by bonerdonor99 on June 9, 2021 at 12:22 pm

    1st grow: Grand Daddy Purp; Purp Kush; Purp Haze in a Gorilla 4×4 under a Mars Hydro TSW2000 at 24″ high. Started them under a Germination kit 25W dome bulb n they stretched like crazy. Moved them to the M/H LED @ but the power was still set too low about 100 PFD. Found a chart showing seedlings should be at 200-400 PPFD, so dialed up to 300 PPFD (79*F/ 70% R/H) n they seem to be responding well…What is everybody else running at n do my plants look ok @ 12 days old????
