On this stage i simply put the seed in soil and add a bit of tap water wich was left under the sunlight for three days. Later on i check PH levels and root growth for transplanting.
I suggest to use some dark towel or duck tape to cover roots area from direct sunlight or simply use a dark plastic bottle if you wanna give a try.
Te soil was mixed also with half tablespoon of RQS Bat Guano for extra ( P ) and extra ( Ca ) and a bit of epsom salt. I surely add mycos later on when transplanting
