I use two virtual sun tents, yes they have small light leak at a few seams but for the price u cant beat em. I got my first 4x4 for $110 and the second was $130. mostt places want around $250 for one 4x4 tent. I veg in one flower in the other. Same room in my house and havnt had a herm. But I dont go in the room during the flowering tents dark time. unless its in a high traffic room of your house I wouldnt worry about it.
