I have 3 strains that cracked open 8 days ago and are growing really slowly. Is there any reason why this is?
They are In 50/50 mix of coco and compost with perlite and the temp is around 77F under 600w HPS
I don't have an answer to your question, but I agree it should be larger at that age. Could just be the strain or that particular plant - but it looks healthy.
Give it as much light as you want until it shows signs of heat stress/light burn, just let her do her thang give it a week or two and you'll think it's silly you ever worried about it so soon, good luck man
seems a bit slow - but I have had that before and when they get to the first 5 leaflet leaf it takes off....but I always use hygrozyme, kangaroos and Microbe Brew (half strength) on seedlings so I know the roots are building. I have some that have popped on the 24th and yours is bigger.
