the 4x4 will work well. can your light have cooling ducts connected to it?
tinytoon Reviewed by tinytoon on . Which size grow tent would best be sutible for a 400w hps light? hi, i just ordered a 400w hps light along with fox farm ocean forest soil and foxfarm s 3 pack nutes and a 10 pack of 2 gallon grow bags, also a 4" inline duct fan. I am going to get a grow tent but am debating on 2 sizes. with a 400w hps, would i be happier with a 4x2x5 or a 4x4x6.5 grow tent? i will be using the 4" inline duct fan to ventilate the tent when i order it. Thanks guys Rating: 5
