start flowering NOW ! 150 watts can't penetrate that deeply, if you can in the next 24 hours see if you can grasp the scrog method of growing then you could veg a little longer otherwise wait till next grow.
150 watt lights can be closer than what it loooks like where you're at.
it'll last a month or so refrigerated. I've heard it can be freeze dried to extend it's life.
best way to catch, lay the male on it's side over a stainless steel bowl without a fan blowing on it.
I live in Vancouver so I know the VSB is legit, how good their (expensive !) shipping to the US is I don't know.
Never heard of the other companys EVER !
