But hydro produces bigger yields and thats a fact”
You are confusing fact and myth my friend. Fact is, you get higher yields with more experience, and usually, there is only a correlative connection between growing on hydro and higher yields. Many people have learned this, when they made the full cirlcle, returning from hydro to soil, only to find, they have the same result. Only benefit is a (much) shorter veg time.
