i plan on building a 55 gal. drum with 2 mountain bike tires, wheel barrel style...
last year i hauled 2 -5 gal. buckets per plant. for 25 plants each day i watered.... hand
watering sucks ass, but it makes u strong and ripped and the ladies love it.
use tarps under thick brush to use as a rain collector. under thick brush a camo tarp would be hard to see from an air plane or helicoptor. just a thought.
Just back from helping a friend put in 250M of pipe to avoid a lot of this work and what ICs late great Silverback termed "The dreaded path" .. dry country shows footprints from just one visit, carrying a lot of water makes your footprints even more noticeable. Using an irrigation system with Dry Cell 12v batteries and electric pumps [quieter and seem to have a better lift than petrol ones] can save a lot of work and keep your grow safer and more secure.
Best of luck mate.
You know you could always dehydrate the water to make it a lightweight concentrate. This way you could carry more and just rehydrate it on the spot!
If you know anyone that works at a mcdonalds or resturaunt of any kind, the bladders that milk shake concentrate/ choclate milk and other stuff comes in makes great water bladders.
I once did a grow using milk jugs (the screw cap type) I had two in a backpack and two in each hand, I would hold them in my hands facing behind me (if that makes sense) I didn't have to walk nearly as far as you though. I like the soft pack approach for a backpack. Be sure to have plenty of drinking water for yourself, you don't want to have to drink stream water. Good luck with a hefty harvest.
I got a chuckle out of this, nothing worse than carrying tons of nasty water that you wouldn't want to drink & having none for yourself...... that was me last night.
You guys need an atv of some sorts, drop off in car, get out of there, come back later on atv and get it moved, just do alot and then you won't have to lug suspicious backpacks around during the dry spell.
