They're damn good timer circuitry thats for sure.. I used to use one to control a relay system that could handle more power than these are rated for for lights, and I was running a drip system, so coming on for watering every 2hrs during light was pretty perfect..
Still though, for our purposes, the design I posted can accomplish everything those timers did.. All I'd need to do to mimick my pump activity on a 24hr day would be to set my diy timer to come on for 20 min every 2 hrs, and have my timer plugged into a generic timer that kills it totally during lights out..
If I can crack into one of these timers without destroying them I'll reverse engineer one.. I assume there are proprietary ICs that make it a nuissance to recreate, but maybe....

alot of the brinks timers are mechanical no chips inside i looked i was going to ask you how to mod it hahah. i have several timers even the digital one uses a mechanical clock mechanisim you set by hand...

No, I was talking about back in the day, when I had a drip table.. I used to run the pumps for 20 minutes every couple hours during light with these timers..
I was saying I could mimick that routine with my designed timer by setting the day length to be 2 hrs, start time = 0, and stoptime=20, and then plug my timer into a 24 hr timer (or another one of mine) set for 12/12.. Although with it plugged into another of mine you could make it any secondary master time-frame like 6/12..
Oops, no, for that to work you'd need to remove the 9V battery..

You don't want a ton of potassium as it can hurt yield if too much is applied in flowering, but I think you'll want more than that ratio-wise..

Interesting concept. Why 6/12 though, I would think day/night timing should be equal as with 12/12. Maybe 8/8, so you get 3 cycles every 2 days.

Take note: this is just a suggestion for an experiment, most likely won't work, but would be cool.

I've been reading up on this a lot but haven't seen any proven results. I gave my plants 36hrs of dark before 12/12 and I started seeing buds on Day 10 of flower.

I just started, so I'm happy with 12/12. But if I can cut my electric bill with some new lighting schedule, then it's worth a try.

one idea as to your 220 v timer is to get a low voltage transformer and a relay that can switch your 220 volts on and off.
just use your 110v timer to run the transformer and pull in the 220 v relay

There is a nice thread in the DIY forum that could be minorly adapted to achieve that.. Its a pretty easy task, but you need to know what you're doing for damn sure.. Its not quite the same as building your own cfl reflector..:)
