im using fluorescent lights right now would it make any difference if i change my lighting to something different??
i know lots of the people on here use them for clones ,seedlings ,and some for the veg period , but if you got a metal halide ,or high pressure sodium light you will see the difference ,the first is usually for veg period the last for flowering , i use both for the flowering period ,and it works for me ,i believe if you are in the u.s.a you can get good l.e.d lights ,but i have yet to see them in oz ,for growing.
hope it works for you ,lots of others on here with more knowledge than me ,so see what others say ,but i get the general opinion is the more light the better.
