So you're tired of refilling gallon water bottles and throwing them into your backpack to schlep them out to your remote growing location?
Me too.
So I bought one of these:
It's a solar camp shower, which I actually may use for its designated purpose someday. It's made of durable plastic, holds 4 gallons (they make them in 2.5 and 5 gallon sizes too). It has a shower head that has a snap action that closes it, which works very well.
It was about $20 at REI. Seems pretty damned solid. Plus, since I bought it at REI, if it craps out, no questions asked return. Not to mention the 10% off ...
I took my 10+ year old backpack, which had some convenient holes already punched in it, and dropped this bad boy in there. First thing I did was to remove the bar at the top which prevents it from fitting well in my bag:
This was as easy as a slit in the rubber and it slid out. It could easily go back in.
Next, I attached the handle at the top to the carrying handle on the top of the bag through a conveniently located tear at the top of my bag, using a strap that came with the reservoir:
The pack has its valve at the bottom, also nicely located near a hole in the bottom of the bag, which I pulled the tube through:
And ... that's all! Below you see the completed pack.
I used this for the first time today, and it was freaking awesome. Show up, pull out the hose - without taking the pack off - drop the head below waist level, and pull the head to get water flowing.
I don't have to set my bag down and pull out noisy water bottles, or at all between planting locations.
It is totally inconspicuous. It looks like a hydration pack - and can be used as one, as long as you're not loaded with nutrient solution.
I can't fit four gallon bottles in my pack, but I can easily get four gallons in my pack with this guy. I think I could have even fit the five-gallon monster in there.
I'll be using this quite regularly, so I'll post if I have any durability issues.
