This is a DIY video to build a 35 min repeat timer with 50 second intervals for Aeroponic and Hydroponic applications. This video will show you what timer and tools you need and how to construct it in a very easy to do simple way. I have done 1000's of these and other aero projects that I will upload later on so please subscribe! If you don't want to build it your self, visit GrowColt.com or www.ebay.com/sch/chirocolt45/m.html to purchase one cheap from me. Hope you all enjoy!
