Hello,

We need some ideas as to what to do my daughter's expt. on. Thinking of comparing grow of swedish ivy in hydroponic sysem vs. soil. Or maybe 2 hydroponic plants and comparing nutrient deficiency such as nitrogen. Any other ideas or comments?

Please help.

I didn't find the right solution from the internet.
