hi ledbud -yes well spotted, it is a 30l. going to have to put a ruler in there or something its kind of hard to tell the size since it always fills the frame!
when I repotted and moved things around, I picked the tallest plant and put it in the 30l airpot. there was not much in it, all six were strong and looking very healthy but this one had a few more inches to it and sat above the canopy.
I've put together the progress so far in a short vid. this one is playing very fast, about a second per day. so days 2 to 45 (its day 47 or 48 now, running a bit behind)
ah- just ignore the day numbers towards the front of the video, they need fixing but just didn't have time yet. 11 seconds onwards the day numbers are correct.
