that part i haven't figured out yet. i was going to use the other end of the cool tube "open" when i first get the HPS going and see how it works. the room is not air tight at all so i shouldn't have to worry about the negative pressure.

and i bought a .5A, .75A and 1.0A 120V to 12VDC transformers to control the speed of the bilge blower. just swap some wire and i have a 3 speed bilge blower

when i do use it, the end of it will be on the floor under the tubs. i have a 6 inch inline fan to exhaust the HPS thru a cool tube. the 3 inch is just to bring some fresh air in.

what's up ICB?

very nice. i love DIY.

i'd get a filter bag to protect the pump from anything getting into it and clogging up the sprayers. most aquarium suppliers have them. even some hydro shops

i just started seeing commercials here for a retrofit foam insulation company. it looks like they drill holes in existing exterior walls and pump it in. our house is from the mid 80's and i've got to believe that the R value of our walls is pretty low. prior to this winter, i blew in insulation in o...
