Cheap, high-quality nutrient sources?
I'm new to this, but am growing (or plan on growing) strawberries, tomatoes (lots!), salad greens, herbs, elephant garlic, roses, and a bunch of other stuff.
So far I've been using Gen Hydro's Flora line and the plants are doing wonderfully. Now I'm wondering what I can use that'll make them do as well but cost a bit less.
So, I've got a couple of questions:
1) the expensive nutrient mixes seem to come in 2 formulations: one for the vegetative stage and the other for flowering/fruiting. Does switching appropriately make a big difference in plant health or yield, or would a good general purpose nutrient mix do about as well (with PPM adjusted appropriately)?
2) What nutrient mix are you happiest with? Anyone avoid dry mixes for any reason?
3) Is there really any reason to use any particular dry mix, or are they all about comparable? Is it significantly cheaper to mix your own from scratch (and if so, anyone have a link to a good recipe?)
Thanks. Just trying to make sure I'm not making any major mistakes, but I'd like to avoid paying too much money at the same time...
