Description

A digital or mechanical timer is a helpful addition in the process of automating your grow space. The timer can be used to control light hours of your lights or for an automated irrigation system. 

Using a timer makes it easier to be away from your grow space, while at the same time ensuring your plants are getting what they need, when they need it.

Recommendation: If you don't mind the extra wiring we highly recommend the SonOff range as its much more versatile.

Note: You will need a contact relay with a timer if you plan to use HPS lights as the inrush(to switch the lights on) is very high and will damage your timer.

QnA

Should I get a mechanical or digital timer?

Both mechanical and digital timers are accurate but their are some advantages and disadvantage for each. The digital timer can only set 8 on & off programs, where the mechanical one can set one every 15min. The digital timer will remember its time & setting when the power goes out however, the mechanicals clock will need to be recalibrated. 

Can I run an HPS light off a wall timer alone?

No, you will need a contact relay to handle the inlet surge created by the HPS lights on start up. We recommend the contact relay with an inbuilt timer: Contactor Timer - 5 plugs.
