I was thinking about getting a portable AC - What kind did you get, The smallest one I could find was a bit larger than I would have liked, probably about 14" square and about 3.5' tall.

I've got my box next to a window air conditioner, but its not vented properly, so the door needs to be open to cool it off, kind of a drag. Especially since it looks like the sun is sitting in the corner of my room!

What strain are you growing? That will ultimately depend on your yield, and of course how you treat your plants between now and then. What nutes are you using now? What are you going to use for flowering?
