deaming jamaica solocup

Let's try this challenge .. a fast flowering seed ... sativa ... jamaican? and I leave with the jamaican dream .. for the little space I made it sprout in the middle of rockwoll not having glasses of the right size, I made do with a biodegradable glass .. but it will not last long for now this measure in Italy is difficult to find I'm not going to change it, just fertilizers and lots of water temperatures are a bit high but in vegetative they are fine The light is set from the first day to 12/12 in the jar I used 90% coconut and 10% perlite I put a few balls of expanded clay at the bottom of the glass
