# Orchids forum: Fertilizer question

 Name: lindseywesley chapel, fl sugarcaneApr 10, 2017 4:12 PM CST 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?lindsey

 Name: Jim HawkOdessa, Florida (Zone 9b) hawkaricaApr 10, 2017 7:29 PM CST 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.

 Name: AliceSaint Helena Island, SC (Zone 9a) ardesiaApr 11, 2017 5:17 AM CST 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. http://www.calculateme.com/Vol... 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. Minds are like parachutes; they work better when they are open.

 Name: lindseywesley chapel, fl sugarcaneApr 11, 2017 10:04 AM CST 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 lindsey
 Name: AliceSaint Helena Island, SC (Zone 9a) ardesiaApr 11, 2017 2:35 PM CST 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???

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.
 Name: ElaineSarasota, FlThe one constant in life is change dyzzypyxxyApr 11, 2017 5:27 PM CST 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 . . .
