Better off starting without a herme seed. You may have problems later. You will have to take some clones from it before it flowers just to keep the strain on the shelf. Then you will have to grow out the herme seed mother to make sure it does not herme. Then if it does not, but it probably will herme, is it a keeper? I would instead grow clones from the tried and true mothers. You can take clones from them up until you switch to 12 hours. You know what the final product will be with clones. No guess work. Another tip on starting seeds. I wrap seeds in a moist paper towel then I wrap the towel with aluminum foil to keep the moisture in. I then place the towel in a warm place like the top of my fridge. The waste heat the fridge gives off warms the seeds and they usually pop in one day or two. As soon as they pop start planting them in pots or rockwool. Just my 2 cents
