You're going to need to involve others... and have absolutely NO expectation of success with this grow, sorry! FIrst of all, your grow is going to need more than just water, will it not?!
Issues pop up unexpectedly that will need to be resolved so you're going to have to rely on whoever you get to help to accurately diagnose problems and treat appropriately... Unfortunately, I had a friend who I relied on to take care of my grow for one week... she diagnosed a toxicity as a deficiency and really messed up one of my plants which never completely recovered.... shit happens....
Good luck...
