First off I've been on this forum for a few years and I read a shitload so please dont flame me for not doing my own research. I have and continue to do so. Just looking for some friendly advice from some of you blades with useful experience pertaining to my specific project. I've got a couple successful small grows (thanks to Grasscity) under my belt using homeade closets and a single 600 in a cool tube cooling via filter>fan>cool tube>exhaust with passive intake. Temps and humidity were never an issue previously but all that is about to change and I'm looking for some setup and equipment advice in order to minimize my learning curve. The new setup is a sealed 9x15 flowering room. I'll be running 4 600 Galaxy digital ballasts in cool tubes. My inclination it to run a 452 cfm vortex fan (cuz I have one) through the lights, in taking from the utility room and exhausting into the main part of the house in order to reduce temps. I have a Sentinel MDt-1 that I'm hooking up to a Sentinel HPH-4 to run lighting duty at 240 volts. For CO2 I'm contemplating a Sentinel CPPM-1 Hooked up to twin 20# tanks for enrichment. I'm not keen on the burner thing due to my cooling concerns and budget for the type of cooler I might need to deal with the BTU's they generate. I could use some advice on this part. I have easy access to natural gas so it wouldn't be hard to setup. Cooling is my biggest concern because I have no idea what I need. I already have a portable 13000 BTU AC unit that I was planning on using. I could probably sell it for $200 online and get something else if this wont do the trick. I dont have a huge budget so I cant go out and spend $1200 on some fancy shit so that's not an option but hit me straight if you know the right way to do this. I'll probably need a decent dehumidifier, a recommend on that would be appreciated. Also I was thinking a CAN 100 with a 700 or 800 CFM fan would do the odor duty but I'm a noob to the sealed room game so set me straight if you think it's over or under kill. Thanks in advance!!
