Mpx stem Maris garden pre questions

a. With your  'big project' in mind, what are some things do you think you have to pay attention to?
b. What are 3 things you need to learn tomorrow?  explain each one. DUE FRIDAY

When we go to Mari's garden, I need to look at how they make efficient hydroponic systems in very simple ways. By doing this, we can figure out a better guide line and also see how they reuse the water and what nutrients they put in it. Looking at the hydroponic systems might give us a better understanding of how hydroponics works. If I had to choose three things to learn tomorrow, they would be what natural way can we restore the nutrients in the water, what types of plants are the best for hydroponics, and how long they take to grow.
         I think that we will need to know how to naturally restore the nutrients into the water because first off, we have to be able to sustainably grow our plants without the use of non organic materials, and secondly, if we can't then our plants will die.
We need to know what types of plants will work when we use hydroponics because when we do the project, if plants that we use don't grow, were in a bad situation. We will also need to know how long every plant takes to grow. We want fast growing plants so that we will have room for error
