Anyway i am starting my very first grow in a 59cm wide,46cm-long and 193cm tall closet.I am currently considering two plants(if the pots fit in it im growing it)and i am weighing between a 250 hps and a 400 hps for flower with a cool tube.The only thing that really worries me is how much heat these hps generate so im thinking would a 400/250 hps make any heat relative diffrences and does the cool tube really help with my heat issues whitout ventilation attached to it ? Do i have to go the full way to extraction fans and ducting(the closet is in my bedroom) ?
unless you plan on keeping your closet open while lamp is on, you will definitely need some sort of ventilation. heat from a 400w is manageable but you still have to evacuate the hot air and keep fresh air coming in jm$.02
well i will probably end up drilling a hole in the bottom and using this guys extraction/Cfilter fan for extraction http://forum.grasscity.com/do-yourself/1286780-build-pc-fan-carbon-filter-combo-your-stealth-cab-pictorial-stews-guide.html.But is the cooling tube effective anyway ? It costs about 65 euros where im from and if it reduces the heat less then 20% i wont go wasting my money for nothing
