If you need irrigation, drip irrigation is the way to go. The little sprinkler emitters are a close second. The beauty of drip irrigation is that it is so efficient with its water use. My favorite watering system is from dripworks.com. They are located in California, near the Bay Area. I don’t know what shipping can be done at the moment, but they are affordable and very high quality.
I personally love to use a drip line with .5 gallons/hour output. This is a nice, slow water release into my clay soil and I find that 1-2 hours can give me 1-2 weeks worth of water.
Nice job using the old hosing. That was a clever idea.

i'e gotten a lot of my stuff from these folks and they have lots of good info in printed catalog, that's how long its been, iim guessing online is about the same as what they put in printed stuff years ago

Do you think there will enough pressure to push the water through the hose or drip hose?

Bigger emitters will offset low pressure, the higher the gpm rating the lower the pressure needed to flow. You won't get the rated gpm but you can offset a lack of pressure that way. Depending on where you are a 350 gallon tank isn't going to do much for water on a 3,500 square foot garden... That would be one gallon per every ten square feet, one watering would empty the tank. Soaker hoses could also be used for very low pressure systems, in fact many systems have to run pressure reducers which would not be an issue for you.
How is this 350 gallon tank refilled exactly?
Eric Hanson wrote:Annie,
The problem in your case is going to be pressure. Each 2.3 feet gives you 1 psi. My drip emitters need a minimum of 10 psi if I remember correctly. Unfortunately your 3 feet is just not enough for what is called a pressure compensating emitter which gives off an EXACT amount of water over a very wide range of pressures. This is nice because a single line can run up and down hill and the first and last emitter and every one in between give off the same amount of water.
There are zero pressure emitters, but you can only run about 20 feet or so before the emitters start to give off different amounts of water. It still can be done, but it makes things a little more complex.
But Annie, if that is the water you have on hand, and if you want to try drip irrigation, then by all means do so. The company I recommend is Dripworks.com. They have a great selection of drip products at reasonable prices.
Good Luck and please let us know how things work out!

Can you hear that? That's my theme music. I don't know where it comes from. Check under this tiny ad:
