A lot of friends asked him about soilless cultivation using this cow dung as a direct substrate Oh, okay, this is okay. We've used it before, we've used it twice, and then it's out The advantage of using cow dung is that the price is cheap now cow dung on the market One party should the price seems to be in thirty or forty bar such a price is basically a labor cost It's a little bit more cost-effective but using cow manure as a soilless culture is something that we growers have to learn a few things about otherwise we might have a problem with the first one The air permeability of cow dung is very good, but its disadvantage is yes Water and fertilizer retention is not good, so what if we grow it as a substrate then you Use a fertilizer applicator to water as much as you can otherwise your labor costs will be too high like what happens in the normal summer, when the tomatoes are about 5 or 6 ears That day's quantity is basically a tomato in One catty half to two catties such a value So you may need 10-20 a day when the water retention is very poor, so try to use a fertilizer applicator with a regular watering machine You can schedule it and then you basically don't have to worry about it for a few days.
