Greenhouses

I was looking on walmart.com and these Walmart.com: Garden & Patio: Lawn & Garden Supplies: Greenhouses intrigued me has anyone used one of these as a growroom and can you see completely through them and tell its weed growing in there?

i would grow a shit ton of veges and stuff before actualy growing pot in it just so every one gets use to you having it...especialy the cops...

i need 3 of the 8 X 12's. very nice.
