As far as rez size goes....it's completely up to you and how much work you are willing to do to keep things in balance. Smaller rez, more monitoring of numbers and more rez changes, more nutes etc etc...(ps...I love it when rhizome says things like "biomass ratio") As long as you keep your share of it in order the plants don't really care.
As Rhizome said....the ratios are important to keep in balance. It doesn't take long at all for numbers....while looking similar to you.....look very different to your plants and we all know it's not about you.....it's about the plants.

This is a question regarding PPM and top-offs: Vegetative Setup T5 Fluorescent Drip Irrigation 18 Gallon Reservoir 18/6 Light Cycle 10 min. Feeds 3x Daily Lets say I start off with PPM of 550; after 1 week it goes up to 800. I know to bring it down you simply add water. This is a "top-off," correct? How would I measure the amount of nutrients it needs? Will there be a time when the PPM goes down? Finally, as the plant grows it will need more nutrients per top off? Is there a set Rating: 5
