Mylar Grow Tents?

I saw a few on ebay, does anyone have any experience? Are they worth purchasing?

this is the one im gettin http://www.htgsupply.com/Product-Grow-Tent---Size-L-55-x-55-x-79---Silver-Lined.asp

Mylar interior you mean ?

I thought that was standard with tents now .... so your asking if tents are worth it ?

A room would be better ... but if your only option is a tent then YEAH ! go for it

i have to disagree i belive tents are more adequit for growing but everyone has theyre own opinion
