I'm planning a couple of decent sized outdoor grows this year. 4-5 sites, 8-10 plants per site ( I guess "decent sized" is a relative term) Anyhoo, in case I need to water, I'm looking toward rigging up a water pump system for at least one of the sites so I don't have to carry water. Can anyone recommend a solar and/or battery powered pump that would push water through any type of a hose over a good distance, say like the length of 3 or 4 football fields? Doesnt have to be a high gallon per hour at the outlet end..... Just need something that would eliminate carrying buckets and leaving a trail.....
