What's up people's? I have a few questions I'm hoping you all can help me with.
1. Can I use the soil from last grow? Or do I need new soil? The last grow I fed them on the heavy side by accident (was my 1st grow).

I used 5 gallon Phat Sacks but they were barely half way full. Can I just add new soil to fill the containers?

2. Do I need to change my lightbulbs? They were brand new a few months ago. I have a 400 watt setup with MH & HPS. I used them both for 2 months each.

3. This will be my first time trying autos in my tent. Do I have to buy them different food or can I use my Go Box nutes?

Thanks in advance for any help that you folks may have to offer
