definitely go for the 400w as long as you can control the heat.

Just starting to grow and need some help Hey :) We just joined this site because we have been moving around a lot and finally found somewhere stable to live. After growing outside and not being too successful, we are now trying to move to hydro. We want to grow anywhere between 4 and 6 plants at two feet tall. We wanted to know if a 250 hps or 400 hps would be needed. We kind of want to keep the electricity low but also want to maximize plant potential. Also we wanted to know if a 5-10-5 solution would be a good root stimulator. Rating: 5
