yup, so far I'm happy with my progress, a few issues have come along since I started but nothing major and nothing I couldn't diagnose and deal with quickly. Initially it was cold slowing the older girl down, and I lost my original #2 seedling 4 days after breaking ground, she had issues shedding her shell and tore one of her cotyledons pretty much clean off, with the cold and physical damage she never recovered.
Also had a small over-watering issue with #1, not finding anyone growing in a medium quite like mine I've been using best-guesses based on coco, super-soil, and ffof grows, but my water-retention seems to be much higher than all these so it's been alot of trial and error finding the sweet spot, as my mix can feel bone dry for a couple inches down but stays saturated below that for up to 2 weeks outdoors when i grow my tomatoes. What I've disovered is that if i'm getting run-off I've over-watered.
Somewhat related to the over-watering and to my mix being recycled refreshed and amended outdoor raised-bed garden mix, I today discovered I have a case of fungus gnats I seem to have brought in from outside. I am quite sure they are gnats and not root aphids or a similar disaster, and will begin treatment tomorrow, would have today on discovery but it's a holiday, all stores closed. Picking up some BT.i. tomorrow. Took a while to find the source, I've been checking my top mix layer daily specifically to watch for something like this and never saw the larva, which is why I got worried when I saw flyers, seem to indicate aphids. But thorough inspection found the little critters wiggling away in my drainage holes at bucket bottom. Here's a couple pics I managed to get to assist me with gnat/aphid ID.
As can be seen, long thin antennae, 3 segmented body, no tailpipe, wings not quite as long as body, combined with presence of black-headed larvae in drain holes, 100% confirmed fungus gnats. The great genocide begins with the dawn light, or at least at the opening of the local Big-Box.
