Well the only difference with the P100 and the P200 is the lights in the AG, the 200 has a lil bigger stock lights for the AG hood, and has different setting, like super grow or somthing, that keeps everything on 24/7
Yep, the 200/deluxe have 3 lights in the hood and have a SuperGrow setting thats kind of hidden in the machine (doesn't say SUPER GROW) but you hold the select button for so long until it starts blinking then you know its on super grow. I got the 200 for that feature specifically so I can keep my pumps running 24/7.
i got the 200 i use strawberrys and hold the light down to keep the pump on 24/7 and manually turn the light on and off till i hook up my hps..and rip of the ag hood
