Bag seeds (gas pack)

2nd first attempt

4 bag seeds from different gas packs, germination in rock wool cubes, I had started 5 seeds before but did not have adequate DWC equipment or nutes... These 4 might go in soil and I still have 3 of the 5 original seedlings in a Savvy Grow 6 site DWC system hoping to save them. They now have enough bubbles Any help or advice is welcomed
