Hi guys, i'm searching the net for a timer that could do a 16/2 light cycle. Just 16 hours of light and 2 hours of darkness. Is it possible? An hourly timer does exists? Have a nice day.

good question... I know I have a timer I bought for my aeroponic set up a few years back... that you could set for so many seconds/minutes/hours on, then seconds/minutes/hours off... but I only think it went to 4-6hr max..

I went and dug out the box is what I got.. you can set it to 15 seconds to 13 hours on.. and 15 seconds to 13 hours off... it's almost what your looking for..

let me dig some more... maybe I'll see a 16 or 18 on / off "adjustable recycling timer" ( key words I used to find mine)

Thanks JGG, i'm gonna dig too with your directives, i asked this question at the growshop and they said: "whaaat?" ahah i'm a kind of experimenter (i don't know if is a word in english). I noticed that many of my auto strains after 16 hours of cob are a little bit stressed, maybe just too much wattage but it's 31w for sq ft and the distance is perfect (or maybe just a coincidence in my last 2 grows). So i'd like to try this kind of light cycle, side by side with a 18 hours of pure cobs and 6 hours of 6000k and 660 nm ad 1/4 of the cobs wattage (try to simulate the sun in northern emisphere when is never going down). I know, keep it simple..but for me it's very funny to mess with light cycles, nutrients, types of lst..ahah..have a nice weekend.

The simple Sonoff's should work, you can get 6 off Amazon for about $36. They work great for me, I run a regular schedule but they have a loop timer function, I think that could cycle them on 16 and then off 2
