Try your circuit in this form: Email Required, but never shown. You cannot drive the IRF in the manner shown.
The LED dat to easily see if the valve is open or closed. The arduino outputs 5V which is just over the threshold voltage of V Datasheet: My basic idea is that if the soil gets to dry the arduino sets the gate voltage, which turns the transistor on and the valve opens.

However I build the exact same project some months ago and used the exact same parts – the same resistances, the same transistor type and the same valve and it worked perfectly with a 5V gate voltage. Thanks a lot, now the circuit works exactly as I wanted! I learned from another thread here that this makes sense, because a higher gate voltage will let more current flow through the transistor. I built this circuit as part of an automatic irrigation system and I am not sure how high the gate voltage should be: When I connected the gate pin of the transistor directly to the 12V power source the circuit worked as intended and the valve igf3205.
If the circuit is connect as in the picture only 0. I use a IRF transistor, which might be a bit of an overkill, but it was the smallest I had.
I suspected the transistor to be broken, but I switched it out several times and the results were the same.

Running your Arduino at 5 V this should work ok out to a couple of Amps.
