Product description
Matrix Regulator 1 L – concentrated plant stimulator for regular tent grows
Already happy with Regulator and growing in one or two tents all year round? The 1 L bottle keeps you going for longer between orders, without tying up as much money as the 5 L container.
Why growers use it
The idea behind Regulator is efficiency: if the plant takes up fertiliser better, you can feed a little less and still get strong, deep green growth. That makes it interesting for growers who want to tighten up their feeding schedule rather than keep adding more.
What the manufacturer says
Matrix Regulator from Fenix MTX (Germany) is a highly concentrated additive that, in the maker's words, makes growing a lot easier. It builds a strong structure with deep green leaves and strong fibres, and improves fertiliser uptake so you need less fertiliser. Fenix MTX also says it helps plants cope with cold and heat stress and supports larger flowers and fruits.
In practice
Fenix MTX doesn't publish a fixed dose on its product page: you dose according to the Matrix MTX feeding schedule. Shake well and check EC and pH after mixing. When you first add Regulator, lower your base feed slightly and watch how the plants respond over a week or two before you settle on your levels. Keep the bottle closed, dark and frost-free.
