Never used LEDs and am sprouting Auto Wh. Widow, Blueberry and Northern Lights.
Picture was 5 minutes ago.
Coast of Maine Platinum mix in pots.
Seedlings 2 - 3 days old.
Bottom of bulb 7 inches from top of pots.
Temp at top of pot 76 F.
LED Light - 33 watts
Are my seedlings stretching? HOW FAR above seedlings should I keep this bulb?
These will got outside in bags shortly.
Update it. Korona was name pre virus. And center PPFD will be high. Distance is also a factor. I can break 200k lux at 4 inches from HLG light with all my detectors. Photone matches my handhelds. I would never put a plant at 150k lux btw. Let alone 200.
