I have melon plants in the greenhouse, and one the melon plant have one melon several times larger, it grows strongly every day more and more :) ... I just hope it not get yellow and it holds this green color strong . Some balls turn yellow quickly when they are small and then they fall off... but I believe this small ones did not get good pollinated, some balls don't get their dust in time and fall off , but...but for that the four melon plants that stand right next to the door smell strong and luckily it brings the bees into the greenhouse sometimes there are as many as three or four of them inside. So other plants are properly pollinated.
I was use here my Sony NEX-5T
