I have a 400 watt hps light. I was curious how many auto flowers do you think I can grow under it and get a decent yield. I will be using soil and 2 gallon smart pots.

14-16. Maybe 20 if you use 6" pots and perlite with AN Sensi Grow A&B 2ML/gallon RO water pHd to 5.5 and 1.5 strength nutes from day 7 to finish.
