One of my seeds didn't germinate, so I had to plant another. The 2nd one is now in the 64L reservoir and is 6 days behind the one in the 1L reservoir.
Roots are starting to make their way down into the nutrient solution in the 1L bottle.
@Fast_Buds, Thanks! One of my seeds didn't germ fully, so luckily i had another GSC from the 3-pack - Let me know if you have any tips for growing in a 1L!!! hahahah
