Need some advice from people who making Makro ferts themselfs. I'm almost newbie in that question. Always used ready mixed fertilisers available in shops. But since I bought another bigger tank, 450 litres, its become a problem. As a concentration is too small, and I need to much for a big tank. Its just become too expensive. Talk to some people, they using some ferts from garden centres, for tomatoes or orhids, but brands they told me are not available in UK. Just wanted to find out what are people here using? And what u thing about these fertilisers?
