Not for anything but those squirel cages you got are only 110 cfm which is almost nothing.A 24 buck inline fan from Homedepot moves more then twice the air.But if anyone is looking for legal stuff I have few things Im gonna sell or ebay in the US.10lb co2 tank, 20 lb co2 tank, 3 inch net pots,600 watt hps light ballast,1000 watt light ballast if interested pm me for prices all is real reasonable and Im good with paypal,cash, or money orders and I dont require a real name just and address to ship to or whatever and I'll mail it out upon payment reciept.Can do it quietly ourselves or for few extra bucks can do an ebay auction if you feel financially more secure with them.
