“Many people start out in a closet or a small tent to "test the waters". I have a 2'X4'X5.3" tent and having the ability to go from Metal Halide to High Pressure Sodium makes this fixture a perfect fit for a simi-stealth operation like mine. I don't have to move plants from the closet to the tent. Now I wish I had 2 of them so I could grow in the closet too.
The temperature in the tent never goes above 28ºC and the room it is in has a temperature of 18ºC to 20ºC. These temps are with either the 250 HPS or a 400 HPS.
The picture is my plants in a tent 5 weeks after going to 12/12 and switching to the 400 Watt HPS.
You will not be disappointed in this fixture. It is small and compact and get the job done and done well.
Like I said,,, I wish I had 2 so I could grow more plants.”
