The plans is to start 7 Liberty Haze feminized seeds and hope they all pop. I plan to run only 6 plants under the 1000W HPS. If I end up with 7 then I will just veg the extra one. This is the first time i've done hydro. Quite an experience.

I removed the 4" duct/vent going into my closet from the ceiling and am replacing it with a 6" vent. So now I have an increased airflow of cold air into the room. This I find is very necessary in Arizona. I took the 6" line off one of the other bathrooms so it may get a little hot in there but there are 2 other bathrooms people can use.
I am also removing the light that is currently on the ceiling and turning it into a power outlet. I am hoping I can stay under 15 amps with a 1000W Ballast ast 9.1 A, Fan at 1 amp and external fans. Any help is appreciated.
