Nano, no no
Meant the update is in size tiny
Definitely get a tent, for the same money, it's so goddamn handy when u can wrap it up to a small bag (the size of a camping tentbag)..
And you don't have to worry about on what you hang your lamps and filters, such easiness.
How about a 120x120x200cm tent, sorry for the metrics
And get a 600W going there, 400W is max for my 100x100x200cm tent..At lowest my MH bulb temps are at 82F (28C).
