Solacure recommends 15 mins on 45 mins off during lights on during flowering… now this makes sense…at 1st glance… it seems like they just want you to burn lights up faster… but then you consider the triggering that needs to be caused causing the plant to grow more trichomes or more on each already existing trichome… either way… it makes sense… 15 on… trigger it… 45 off… grow the trichomes … 15 on trigger it. 45 off… resin production… I think they are on to something with this method 
because if you leave it on… then your just melting away what you previously grew… kind of 1 step forward 2 steps back… seems like just enough to trigger the need for resin production (plant sunscreen) is best for increasing trichomes and sizes of existing trichomes… just want to trigger this reaction over and over without actually hurting/degrading existing trichomes… this is talking uvb by the way… I feel like uva is more of a strengthener…
