Can I run two 600w HPS off my Sentinel MDT-1 timer?

I run two 600s off a 25 dollar timer and have for years. Electronic ballasts usually have a soft start feature that doesn't make such a sudden demand on the line. Anyhow, it's a 1600W timer on a dedicated circuit. I've never had any problems.

that is a pricey solid state timer... but dude is right, digi's start easier than a magnetic. reason being digis use a capacitor bank instead of one big cap, like a mag ballast. the bank creates less of an inrush, more componets= more resistance= inrush is spread over a longer duration of time.
honestly though i can find a relay that costs 10-20$ that will run 2000w inductive all day long... if your nervous use a relay instead of there power expansion module....
a power expansion module is a fancy general purpose latching contactor in a shiny box with a big price tag :/

you can 1440w off that timer....
for power rating in a grow op, use this equation:
(P= E x I) x 80% = safe power
P= wattage E= voltage I= amperage
(1800W = 120V x 15AMP) x 80% = 1440 WATTS
your 120v 15 amp timer will safely handle 1440watts of power.
LMFAO i thought that was a real fuckin' bug for like a minute.

hey man can you please shoot me A pm and let me know how you connected the 2 600's to the mdt-1? I'm thinking about going with it and would be using 2 600's aswell. did you just use an extension cord? thanks
