Helloooo... I'm about to begin my journey but have 1 thing left to buy and the most crucial part.. a light. It's a 80cmx80cmx160cm tent with a 5" rvk fan + rhino hobby cb. Room temperaure sits between 20-25c WITHOUT the fan ON. Would the experienced point me in the right direction on what would be ideal? I'm worried if I go 400w hps the temps would shoot up with the fan ON. Looking at about growing 3plants. I've heard of cobs but there a lil out my price range. Would hps be easy to maintain temp? Or what kind of led? Seen marshydro 300 but would I need 2? Or more W?
