im gonna use an area of 3x3 by 12 feet tall. im more worried about a good fan that isnt too expensive for venting with a carbon filter. im going to duct a cool tube to a carbon filter an fan. vent the clean hot air into my kitchen.
if i understand correctly you have to blow air past cooltube...
im sure the plant could use a general nutrient feed. go light. your right that does not look like an auto of your stated age. you might not be growing an auto.looks like a regular photo plant in veg.
i suck at math. how do i know what size carbon filter i need with a 400w hps. i think most cooltubes are 6 inch ay 400w but i could be wrong on that. would a 4 inch fan and filter work on a 3x3 area? or just go for the larger size and forget about it for a year?
when ppl say cfls are not hot they are talking about the small bulbs where you use like a bunch of them. the large are just plain too hot for most cabinets. i cant imagine how hot the 200w cfls get. like a campfire over your plants
dwc is awesome. no watering, quick growth,easy build.rockwool is a pain in the ass. adjusting ph who needs it. starter plugs work great. germinate them in the starter plugs. during flower you have to top up every couple days, veg you feed once a week an your done.
