Time-R Digital Timer

Brilliant

Full control and easy to programme

If I could give this 6 stars, I would... This timer allows you to preset combinations of repeat settings and daily settings... It's the only timer I have found that allows you to change the amount of hours in your grow day as apposed to being stuck with the standard 24hrs with most other timers. Think your plants would be more productive on a 8hr on 12 off cycle? This can do it and much more with awesome down to the second control :)
