The chilli pepper seedlings, grown from seeds I bought from Woolworths, have been growing at different rates. That is fairly normal but what's slightly strange is that there seem to be two different types of plant growing from the seeds.

When I planted the seeds in the propagator, I divided the tray into 3 and planted one type of seed into each area. This was to help identify the seedlings when they started to grow.

The seedlings on the left look normal, compared to other photos I've seen.

The ones on the right grew in the area where I planted the chilli seeds. They weren't present in the other areas of the propagator, so it is unlikely that they were 'contamination' or present in the compost. They don't look like the other seedlings but I'll allow them to grow, just in case there were different types of chilli seed mixed in the pack.
