keeko Reviewed by keeko on . outdoor irigation hi, I am soon planting a nice size outdoor grow. I will be planting next a creek and was wondering if anyone had any ideas about how to set up a irrigation system. I was thinking if i damed up the creek i could dig trenches that went next to the rows of plants. The trenches would be conected to the damed up creek bringing watter to the soil around the plants. THe only thing about that is you cannot control the water flow. these are just ideas for my next year grow as it is too Rating: 5
