just a tip

if u are going to remove a shelf, screw it firmly to the base board to make the base twice as thick.
It's surprising how much they bend when they have a big fat plant sat on them.
Same goes for u drobe growers - no doubt the base is made of chipboard / mdf & they're not very strong.
A nice plant & pot will weigh 25kg +
*if it will come apart easily, dismantle it & line it with mylar using double sided tape (carpet tape)
Makes the mylar a lot easier to handle & gives a pro lookin flat mirror finish.
Might be an idea to use a low profile grow tray instead of a pot = still plenty of room for root growth, but without taking up headroom.
if u intend on growing just 1 plant, make sure u get killer feminised seeds to avoid disappointment
#but if u live in Canada, why are u doing a stealth grow???
