Light intensity and distance during flower

    I just flipped my girls to flower today. I’m wondering when should I turn my Mars hydro fce 3000 up to 100 percent. It’s on about 60 now at a distance of about 20 inches. Should I turn it to 100 or keep it at 60 and move it to 12 inches above the canopy?

    Agreed wide open and watch for response. Top growth drooping, bleached tips that can favor nutrient burn or be white, and the new growth could look smaller thinner spindly even. First time I ran my growers choice that's what I went through. Sad thing is it favored over watering or deficiency so it took me a few days to realize. It just effected the 2 tallest plants figured they needed more food or ph was off. Wrong lol

    Again: Wide Open, leave a temp gauge at leaf height check every few minutes adjust to suit

    Using the entry level TS600 (2 units) flanking a SF1000 for my flowering efforts; only the Spider Farmer system is dimmable but these babies don't seem to suffer being closer than I'd like.

    They don't need that their just running 300 watts. I probably wouldnt even use the dimmer with 300 watts just adjust the light height.

    That's the light meter I got.
    It's good for spacing your lights to get the same coverage in larger areas.

    Mine the one earlier goes only to 100k Lu

    but you have you know its 1x1.5 = 1U-mol to save you getting the expensive ppf meter
    or about 770,000Lu = 1000 U-mols the best light reading for LEDs(at about 3ft hi)
