Yeah, i didnt say anything about the pots or foil.

The foil is a waste of time, it abosrbs light, doesnt reflect.

The plants will get mighty unhappy being in the same pot, and i doubt theres enough room in the pot anyway.

About the lgihts on the roots. This isnt proved, no one knows, some say its ok, some say its not, i personally think its bad. Naturaly they wouldnt get any light, so that my resaoning.
