hello everyone. this is my first grow i just got the pc box a week ago, the instructions said, just to fill the water till it reaches the bottom of rockwool, later i read on the internet that u need to presoak the rockwool cubes before planting for ph, is that nescescery? because it has been 5 days since i put my sprouted seeds in (3) total, 2 kush 1 white widow, and they dont seem to have changed or grown, i am not sure what to do? whats the best way to start the grow? also if i want to grow on soil, whats the best soil solution i can get and where should i get it, i dont have time to create a mix. when are those seeds normally expected to show growing, what could i have done wrong? I know for one day the water has been up to the seed, but i got told thats not also a big problem. also after the seed had sprouted whats the best way to place them in the cube? any tips/ideas? thanks martha
