I like your grow,, can a blurple LED grow some dank bud,,, Sure it can,, quality bud sure, but your not going to get a heavy weight nor a big donkey cola with blurple,,
But you can smoke it,, get high, and relax,, try to not get caught up in all the debates ,,
Your plants looks really healthy bro,,
grow with hardware you have,, change it later if you want
