hey zypher, loving the diaries you have made. It's a shame those quantum boards have been sold out for so long. Seems demand is only going to grow also. Especially with diaries like yours.Particularly impressed with the really fast growth in the first half of flowering.
I was going to ask you how much shipping roughly is and if you have to pay import duty or tax when it comes through customs?
oh yeah also, i am having problems maintaining temps in winter as it is. if i were to switch from hps to quantum boards would it still be worth it or would i need to supplement with heat, I'm talking 18-20 degrees c without heat, the QB would increase efficiency but i'm worried the heat loss would reduce yield more if that makes sense.
