Just to add my two bits, I have one Secert Jardin Grow tent(DR 100. i think which is the dark room ,,but they have DS which is dark street.)anyway, got it for £60!!! thats off ebay, some said it wouldnt be light proof and shity,,not any good for 60 quid. well its 1m x 1m x2m, has a 600w hps,(abit much I have found ,,it just gets very warm in there. theres a vent fan so its all good now. ) but yeah the tent is great, great price, great quailty. In all honesty I'd get another Secert Jardin DR100 to use a veg rm, as this ones the flowering room,,but honestly its awsum. May not help you much,,but jardin have good quailty stuff,,I dnt think it will be as cheap as that mylar one from the link but cant be much more.Just a recomendation
