I'm so jealous of your ability to grow outdoors. lol Your plants look amazing my friend.
don't stress over the sprout. she'll get bigger. let her get dry.. very dry. a dry medium will cause her to "stretch" her roots in search for water.
I start in plugs and when I plant them I do not water the soil the first day, day and a half.
The plug is moist but the soilless is straight from the bag.
when I water the next day, the medium get's all sinkholey and you can see the roots have already stretched out into the large container. it used to take me so long to get sprouts to grow when I watered them lol.
I just bought 2 big ferns for this little roof outside my kitchen window. gonna mount a "cleat" to the roof so the buckets just chill up there. and behind them will be the female spyder that I got going. it'll be hidden from the neighbors but I won't be able to let her get too big before having to being her BACK in to finish.
