Slow release feed

I have used them for some years and pro growers use them, I find the
moisture release ones much better than the temperature release type.
Both need using with care on some sensitive/young plants. Too much water/too hot can = severe root damage. But yes
they're widely used for very good reasons. I use them a lot but not for everything/all the time.
