Viparspectra are good lights for the price, the xs series is a perfect price/performance ratio while the P series is great value for money for beginners or autoflower and in the growth phase.
Terra Aquatica are great fertilizers, the main TriPart range can be used in everything, preferably hydro or coconut, I came across them by accident, back when they were called GH, I was fascinated by the TriPart fertilizers used by NASA, so I tried them and have been using them for some time and as long as they are on the market I will not stop.
