This question is addressed to super-expert grower: I would change my nutes moving from AN to another brand, less expensive. The question is: in your opinion wich brand has the best value for money ? Thanks
Go organic and you need less. Normal you only need the basics or mix a good soil by your own. I use green buzz liquids/nutritions, but they sponsor me.
With organic you also don't need to check the ppm. If your tapwater is good you also don't need pH fixing because organic do it by itself.
General Hydroponics(or Terra Aquatica in some places) is one of the best value lines I've found. The Flora Trio works great and you can get gallon jugs on Amazon for about each. It's a 3 part system, Grow/Bloom/Micro.
