Guerrilla grow hole prep with coco baskets, see diagram and thoughts

OK so I thought I’d just run this by you guys and gals. Getting ready to start final prepping of my sites and because I’m only going to visit four or five times maximum from start to harvest I am of course worried about watering. After lots of research and lots of help I’ve come up with the following idea. Dig my hole, put some rock and pebble in the bottom, and here’s my thought that I wanted to run past y’all. You know those hanging baskets I got those Coco mats and them that you can get at Lowe’s etc.? Since you can get them round in about a 14 inch diameter the picture below illustrates what I’m thinking about doing.

Pebbles and rocks at the bottom, one of those coco coir baskets, then mother Earth groundswell mixed in with a local dirt, and miracle grow water crystals mixed in lightly and slow release veg nutes.

Then I walk away for 2 weeks back to check, and then return in mid July, then late August and on that check nute up for flower. I like organic nutes and terp teas as a slow release, and then back to harvest, hopefully

I loved guerilla growing it was such a great experience. I grew in many climates in Hawaii and hated schlepping water.
Everything can be seen by helicopters so doing it right is key to harvesting.
Dig the hole as deep as you can through the top soil and well past any roots especially grass roots. Put ferts in the bottom. This will minimize dark green round bulls eyes seen from above. If the plant gets root bound or needs more ferts you can crack the soil at the drip line. Use a shovel and dig and lift a clod, but not toss to the side. Get as deep as you can and drop ferts in the crack or water it. Then just replace the clod.
As for watering.
I would dig 10gallon catchment holes and cover with branches and grass in some areas with clay soil. Big enough to scoop 5 gallon bucket.
In the mountains with rock substrate where you can't dig, in an area with small trees I'd bring in cattle fencing tie wire cardboard a tarp and ratchet straps. I'd make a few hundred gallon rain catchment. Using trees as posts. The cattle wire is the frame. Line with cardboard so tarp doesn't puncture nor rip. Use ratchet straps to secure and support the frame. Which I could then siphon down hill in a hose.
In the deep hole, usually in abandoned can feilds with deep soil the rainfall was good enough not to have to bring extra water much. Soil moist is a brand of acrylamide gel that will swell a few 100% it's size and hold water. Go light with it put it in the lower 3rd of the hole. Too much can cause the hole to heave the plant out and fall over.
If carrying water gas cans are ideal. Very puncture and crack proof compared to buckets like if you stumble. Ergonomic handle for the walk. And looks normal to have gas cans in your vehicle instead of buckets.
