Unfortunately, our first sprout seems to have taken a turn for the worst today. Droopy and still not making any progress of finding its way through the perlite into our tank full of the nutrient solution, it cannot feed. We’ve tried manually feeding it, but we cannot keep that up over the weekend. We are ready for the worst when we get back, it seems that anything we tried to grow in the perlite just wouldn’t work. We suspect it is because of the rather large size of the pellets, which leave little room for any potential roots to maneuver through.
