I have 4 plants (3 - 6 inches) under an T5 8 bulb (40,000 lumens i bealive) fluorescent and I just bought the 500w blackstar L.E.D, It was highly recomended for flowering stage. 2 of the the plants growing are auto flowering. Should I replace the fluorescent with the Blackstar led now, or wiat for them to start flowering????
