Second Grow and Journal

Getting ready for my second grow, my first grow yielded not much maybe an ounce but I made alot of mistakes and am just happy it stayed alive. I was thinking about a soil grow but I already have everything ready for another DWC so here we go. If you guys can offer any advice I can really use it. I already know my biggest problem is gonna be temperatures.

I am growing in my back closet and it is not insulated well at all, I live in the southwest and it will easily be 120 degrees outside. I am installing an A/C duct in the closet to help. has any body used the Igloo type water coolers, should I use this for water temps. any advice is welcome.

You gonna have any pics?
I am using an Igloo cooler for my DWC Scrog and very pleased with the cooler selection.
I started out with a Rubbermaid and converted to a cooler and haven't looked back.
Rez temps stay between 66-70 usually. With no water chiller.

Supz man. First of all, could you give us a little more info as to your growing equipment/setup? Closet size, lighting, nutez, etc? If its that hot where you live then I would suggest trying DWC in a cooler. I hear people who live in hotter climates have GREAT results with them because they keep your water temps down and provide good protection from your grow light to help minimize algae growth at warmer temps. Fans are always a plus. The A/C duct definately sounds like a good idea! Shoot us somemore info and you'll get more info Happy growing
