Skunky Dunk Farms
Cannabinoid Receptor
Honestly i believe the low light intensity along with covering a wide spectrum and temp is the biggest thing that does it.So I feel financially invested in this hydrocloner (damn sunk cost fallacy at work) at the moment but your method is really appealing to me. I even have an 18"x36"x36" tent that's empty right now that I could easily set up like yours...
Basically everything else is redundant in cloning (cut, dip and wet).
