Here is an update on my AI grow, getting ready to start some og kush and i just ordered a new 400 watt light with ballast. i have added some upgrades to the tent, as you can see in 1 picture the 4" heavy duty exaust fan, it has been working well but is not so pleasant to sleep next to. I added a 4" axial fan at the bottom for better suction at night.
my tent is 4x4x6.8. i just bought a 400 watt hps to add to my 150 watt hps. How Many Plants would you think is safe to grow in this area with this lighting?
Does anyone know what the purpose of a ballast is when you have an hps light, i mean can you just plug the light into an extension cord or does it have to be plugged into the ballast and then plugged into the extension cord?
+REP for help
trying to upload pix but having problems so i will do it in the next few days
