I just recently bought this gadget.. and I'm hoping it will speed up my spraying process.

Can anyone help me with the math involved in changing my usual 1 tsp per gallon routine to this format?

If I remember correctly, 1 tablespoon is the same as half a fluid ounce. There are three teaspoons in a tablespoon. So, divide half an ounce by 3 and there you have it. So 1 teaspoon equals .165 fluid ounces. Also, 1 fluid ounce equals 6 teaspoons or 2 tablespoons.

My guess is you are not going to be happy with your new spraying device. It is made for greater quantities than you are using on your orchids.

LOL, I can usually do the math but just thinking about it gives me a headache. I cheat and use something like this. You can swap the units if necessary.

What is the lowest amount shown on the dial on your sprayer. I have a similar one and it does go down to 1 tsp. per gallon. I have to check but I think it even goes lower.

Thanks Alice for pointing out the obvious...yes, by simply rotating the BIG DIAL I was able to move it to a fraction. Now there's still lots of colored water in the jug, so I'm wondering if any food was actually delivered Whistling

I often have too much left and wonder about that. I understand they have those sprayers calibrated to a certain water pressure and I know my water pressure is low so what dilution am I getting???

I hate hose end sprayers because of that! How many of us have a clue about our water pressure? To make matters worse, it changes with the time of day, as city water usage is higher during peak, daylight hours....thus lowering the pressure to an individual property.

Yes, that would be my problem with the whole system - varying water pressure would make the dilution rate vary too.

With the slow growth rate of most orchids, you're not going to know if you're under-feeding them for quite a while. On the other hand, if you give them too much you'll probably know right away . . . D'Oh!
