you have 2 150's in a 5 sq ft cab? Why did you decide to do that instead of like one single larger watt hps? I am just getting ready to build a cab and researching every method there is.
thex420 Reviewed by thex420 on . dry ice=co2??? if i were to take a cooler a 4 1/2 inch or 120 mm in line fan some 4 inch duct and some dry ice and but that all together would this make for a sufficient source of co2 to the plants. i plan to attach the fan to my cabinet from the inside. hook the duct up to the fan by way of flange and run it to the hole in the igloo cooler. there will be about 3 feet of duct. and i am working with a 5 sq ft space in a cabinet. i do not want to have the dry ice inside the cabinet thats why i chose this Rating: 5
