Visible differences can be seen from the two plants after 2 weeks. One appears skinny and rigid while plant 2 has wider leaves and more "relaxed" looking. Both appear to be healthy. Fans are installed in tent, but not currently being used as the temperature is kept between 65° F and 75° F inside of the grow tent, with a small ceramic heater and grow lights. Overnight, temperatures reach below freezing outside which is the reason for 24 hour lighting at this stage of the grow. I do alternate a schedule between full spectrum light during the "day" and red/ blue at "night". Prior to day 10, I was running all lights, all of the time. Day 12: For fun and to assist with smell later in the grow, I planted some peppermint in a third, smaller pot.
