Of about 20 seeds put in to germinate 1 popped up. I put the seedling in a no name seedling medium that I had previously put 5 seeds into. After about a month under LED lights the seedling died. I then turned off my aero-nft system and went about getting other seeds ready for planting. After about 2 days I had 2 new seedlings from the month old seeds that were in the medium. Turns out my pump cycle was too long and the no name medium was holding too much water. I'm trying to find a seed medium that actually does what it claims. I am not having much luck. Sure-to-Grow medium holds way too much water also. Guess my next option will be tried (by others) and true rock wool. I tried growing catnip also but I did not scarify the seeds.

Last year I scarified a group of guava seeds, both mechanically (filed endocarp) and chemically (acetic acid). Neither worked. Of the 5 control seeds I had used (no scarification), 5 germinated, 4 made it up to early vegetative, & still thrive. A majority of the sources I had used back then painted seed scarification as a standard practice in commercial guava seedling germination practices. Yet I obtained opposing results. Go figure. I'm wondering if olive pits would respond well to scarification. A few sources say the endocarp needs to be excised. It does not work--my seeds rotted. So scarification seems a likely priming method for these last 2 olive seeds I have left. Next on my xmas list: some H2O2. Thanx 4 blogging on scarification! Scarification can be a pain to do right.
