I've had many people tell me an led won't flower very well, and some said it would be fine but would just take longer.
Don't get discouraged, just do the best you can do with what you have, that's what I'm doing.
I started a cheap budget grow last month using
A "cheap" Mars Hydro 600w led, rated at 270 actual watts
32x32x62 tent
ProMix amended soil
18/6 light cycle with light hung at 24" above plants
I'm moving mine outside in a couple weeks, but this is what mine are doing 21 days after seed pop.
I have 12 plants in 1 gallon fabric pots in this little tent.
