happy growing!
Wow, lots of info there :stoned:

Could you discuss this ratio(s) and your definition of balance??

Also, could you explain the thinking on the 2nd point, I mean if LED's are weaker at flowering wouldn't you want MORE red????? :wtf:

:thumbsup: I ask because I'm interested...LED's have some serious safety advantages it seems
