        35cm is to close. Try 50cm(20 inches) during seedling. If they stretch too much then lower your light.

            Your plants will tell you how high/low to keep your lights. 👍
            There are 3 things you must check everyday when growing in hydro:
            1) Water level (How much h2o is she drinking in 24hrs)
            2) pH level (change over 24hrs)
            3) ppm/EC level (How much food is she eating in 24hrs)

            I use a CFC for the little ones and put it right close. One per. Cheap. Plenty of light til they are not seedlings and no stretch no burn.

            My $0.02 because I always burn em when I try a stronger light and have to experiment with distances.
