You have the transformer in the same area as your light and plants?
What the hell is a transformer??? you mean the actual fan??? if so then yes it is.

Are you pulling in cool air to blow through the tube and out the otherside of your grow area with no breaks inbetween?
I am pulling in cool air but its not connected to the other side of the cool tube but its very close.

Are you also using an active exhaust to pull the air out and away of your grow area? Active exhaust??? like a second fan to carry the heat away further??? if so then no but i could

What about fresh air intake for your plants is that passive or active? i have a fart fan inside the room that keeps everything moving arround but no the air is not fresh.

i plan on putting a hole through the wall and putting a grate in and then putting the fart fan next to the grate so there will be more intake of cold air.

thanks for the quick reply z
