I have done three hrows, two of which used MC and a real grow light. My plants were very good about telling me when I was giving them too much nitrogen. LOL
I love the ease and results of Megacrop v1.
I greatly prefer 1-part over 2+part fertilizers.
My plants never tell me they're getting too much N or too little P in flower.
These work well for fertilizer storage of larger amounts:

For smaller amounts, a small screw top plastic container is fine.
