Purple lemonade auto

Planted her about an inch down in some promix that contains no nutrients because I plan on putting her in a 3 gall fabric pot with foxfarm ocean forest. I did my research before doing so and read various forums talking about how foxfarm is too hot for seedlings so the jiffy cup method without nutes will work fine. The plan is to have the roots search for water in the first week then she should have a long enough root system to access the nutrients in the ffof with being too small to handle it. I did tare off the bottom and sides of the jiffy cup so she didn't have to punch thru the cup
