Here I will share with you the little knowledge and ideas I acumulated over the past few years of growing tomatoes,and I hope others will share theirs too.
I'll start with a pollinator I made,I've been using it for years and it's extremely useful and efficient.
It is about a meter long,so I don't ever need to bend my spine or stand on toes to reach the flowers.There are a couple of feathers at the end that are vibrating fast,these reach multiple flowers at once and polinate them without damaging them at all.The vibrations come from a motor that spins the counterweight.With this thing it takes only a few seconds/plant,for my 65 plants in the greenhouse I'm ussualy done in about 2-5 minutes depending on the plant's sizes.
Anyone interested I can post more things and instructions but it's really simple and anyone can make it.
