They really don’t care where the nutrients come from. However they take very little to keep going for a long time.
Cell biologist I worked with tested tested this one.
He placed 10 small plants into sterile agar made with diluted Hoagland’s solution. He then sealed the petri dishes with petrifilm (gas permeable). Then placed them under a low light (4 T12’s at 20cm and a 12 hour photoperiod).
He started them about 5 years before I met him. We worked together for 11 years and he never lost a plant.
