I was away for a while, so here's an update after about 10 days. All the seeds have germinated. First the Blue cheese from barneys and then zombie kush and blue zushi at the same time.
The stating pots were only about 50ml in size, so I repotted them today in 2 liter pots.
The Sanlight are dimmed to 40% and are 35 cm apart. The plants will receive about 260 ppfd now.
The soil is a mix of 40% perlite and 60% Plagron bat mix.
