Honestly not sure yet, I want a 2nd tent for sure. I was thinking about maybe running 3-6 autos in my 3x3 and running photos with a longer veg in the 5x5 after I get everything for it. Was thinking the light would be the most expensive thing but after talking about it this morning, maybe I could just get a few 100w units instead. Was thinking about just doing 2-4 larger photos in there after lights were purchased and maybe using as a drying space until I got lights for it. Because the tent and exhaust kit I could probably buy all at once.So are u wanting to upgrade to a bigger size and keep this tent going? Or u gonna just run the bigger 1 to start?
