HTG kingergraden tent

i have been looking carfully at a lot of tents and having a hard time deciding for my mother and clone tent i was wondering if any one has used this tent i have heard HTG tents are junk that they leak light and other problems but im going to have 24 hours of light so thats not that big a problem minus the slight light leak but i also like to know if this tent will kill my plant and and all info would be greatly apprciated want to start a real grow again and other sugestions
o have looked at homebox aswell as dark room but dont have one that will fit the t5 im going to use is 48 inches long without needing a ton of flors

thanks in advance
