Evening all,
With led the important thing appears to be par. So for example I've read that anything over 700 umols is what's needed for flowering. But could you have too much par in a smaller space such as 60x60? Or am I confused and talking out my arse?
That prakasa ironman is running just now only knocks out 420 umols from what I read meanwhile a meizhi 450 (real usage about 200w) is giving out about 700 umols. Obviously one uses about twice as much power so kinda makes sense it would have more par.
So really my question is if you're gonna spunk a 100 quid on a led would you go for the higher par value (within a 60x60 tent)
Does that make sense??
Cheers
