need advice on watering system

i am looking ahead for next spring...i want to do an outdoor grow...my problem is i am gone 2 weeks out of the month...i have been looking at subcool's super soil mix...he doesnt add any nutes...just plain water...and ph is less of a problem in soil
what i want to do is dig a 2ft x 2ft hole 3ft deep and fill with super soil and a buffer layer...what i need to figure out is how to water for 2 weeks...some kind of drip system?
make a raised bed and use a wick system and a buried resivor
i can get 30 gal drums for resivors...that is no problem
it will only be 3 or 4 plants so i can haul the water for them
any ideas,criticism or anything else is welcome
this may have already been asked here...i may not be looking back far enough to find it...if so i appologize...just looking for ideas and comments

You could also add some polymer crystals to your soil.

that and greensand are on my order list bro

what does the greensand do?

Greensand (0-0-3)
helps loosen and areate clay soil

so thats everything you can do...

cause use the gallon or 2 liter trick, fill it up, poke needle sized holes in it, and bury them near the site, it's like an underground aquaglobe

Use a gravity fed system. Using battery operated timers to turn on valves morning and night. So you only have to go up every 7 days. I like to go up every 3 - 5 but thats just me
