I have those red party cups. I filled it up about an inch away from the top with some FoxFarm Light Warrior. I want to presoak my soil because my seeds are in the towel getting germinated. I've had these seeds b4 and they germinated within 24 hrs. So I'm assuming it will be done in 24 hrs again. So I want to pre soak my soil with water for the seeds tomorow. People say its best to give a seedling 6.0 cause roots grow faster with a ph water ballanced at 6.0. So now I'm wondering can I get water put my digital meter in it and set my water up to 6.0 and water my soil with water thats set up at 6.0? Will this hurt the seed or will that be ok if anything the best? or should I just water it with drinking water?
