scatteredholes the more surface area the better. imagine each hole lets a bubble of air thru, what will have more surface area a lot of little holes or a few big hole?
and if the holes are clumped together thats just means you covering less surface area.
next what about seeds? the simplest way to be sure your not fucking up is to drop them in some water with a drop of seaweed extract. then when the tail shows bury them tail down in the soil (loosely compacted and damp not wet) barely in leave the back side of the seed out and cove with a very hin layer of soil, thicker if your soil dries too quickly. if you saw a tail they will more than likely they will sprout up after a few days(like 3-5) by the 5th day i would check on themif they dont sprout after 8 days the seed was no good, plain and simple. ive had very few seeds die on me. almost 10 recently but i have planted 30 of my own seeds in the pas week with a 100% success rate of the ones that shown tails. i think those 10 where just infertile somehow, and it happens too.
