First grow - Mixed tent SF1000

I have placed all 3 seeds in a paper towel method, with two plates making a dome. 36hrs later I have a tap root on all the seeds with the auto purple punch and rainbow cake popping first 🙌🏼 Rather than transplanting I have put all the seeds straight into the pot they will remain in throughout. The medium used is ecothrive coco/perlite mix. 2x 12.5 Litre air pots 1x 5 gallon grow bag that came with my SF1000 kit. 2 Days later - Purple punch auto and Runtz muffin start to show their heads still waiting on the Rainbow cake to break through.... Just being getting light sprays of water every 6 hour to keep top soil lightly damp.
