8 days later
Here's this morning's happy snap - 8 days from the first entry photos showing first true leaves.
Seems odd that the three plants from the same bag have such different growth rates at this early stage - one runt and two bigger ones. The runty one had the jiffy pot sticking up out of the coco about 1cm so I added more coco to bring the level up yesterday. Currently watering only every few days because I'm waiting for the top of the coco to dry out to encourage big root growth - all pots have rootlets appearing in the drain holes now.
I'd appreciate comments on the adequacy of the lighting schedule and lighting if anyone has thoughts ?
