It was used in one of my readers' farms.
(above is the pic of corner board without nest )
( a month plus after Love potion had been applied)
We had only applied to 6 corner boards in the farm that has more 480 corner boards. It was a 3 storey farm.
The result was good. If you had tried and the result is otherwise there could be other underlying factors that you need to find out.
Some of the factors that you need to consider are;
4) Wrong type of wood used as nesting planks.
5) Applying unknown stuff to nesting planks
6) farm design
7) Size and location entrance hole
8) Building material of farm
and many more.
Besides that the way of using the Love Potion is as important as the above factors. Wrong way of using it without following the instruction will not produce result.
It is not advisable to use Love potion together with other aroma. Love potion not only helps your farm to increase nests & birds population but it also helps to identify whether your farm's micro environment is at the best level or otherwise.
