No soil. MIX my friend MIX. You have to learn the terminology. There is a distinction here. MIX is not soil. You want state of the art growing, you use mix and fortify it yourself. It has little nutritional value alone. Don't make the roots work more than they have to. the quicker they grow, the bigger your root mass, the larger your plant and flowers. It all comes back to root mass. Roots have to burrow into soil. This takes time. And buckets above ground have heat issues (heat on the roots will rob you of growth and yield unless you are in your back yard and can monitor it daily. Give them a luxury environment where they can eat and flourish without obstruction and stress. Mitigating stress throughout the life cycle is your main objective. This is state of the art growing.
