Each grow I expect to have some germination fails, for whatever reasons. This is my 6th grow. I germinate all my ILGM seeds as per the germination directions. I make sure to meet correct pH (water & medium), temperature, humidity and lighting suitable for seedlings. The only difference is I usually have my seedlings outside in full sun at or after day 7 of germination.
But this year I started out with 27 seeds, a mixture of JH - WW - WC - AK47 autoflowers + 2 NL Fem I purchased from ILGM in 2017 (the 2 NL seeds cracked within 24 hrs of being in water). Out of the 27 seeds I started, 4 of 4 AK47AF, 6 of 10 JHAF, 2 of 8 WWAF and 2 of 4 WCAF failed to germinate. All seeds that did germinate, popped through the starter medium within 5 days, the majority were up in 3 days.
I have kept the failed seeds. After approx 10 days I removed them from the medium and re-soaked in water, but with no change other than the seed coating has turned to black. Under a magnifying glass/scope it appears that some ends of the seeds have opened but little else. Some seeds when squeezed between my fingers turned to white mush.
A mixture of AF’s did germinate but look odd, even strange, what causes this?. Before I toss them I wanted to share, or I might just wait and see what they turn into.
Again, what causes these abnormalities?
I contacted ILGM and they are replacing 15 AF’s. I appreciate their continued support.
In my short experience I have had 100% germination success with feminised photoperiod seeds like NL#5 - every seed pops.
But the start of this grow has me questioning the science and breeding that goes into autoflowers.
In my mind I am asking, what amount of male pollen is required to make a seed viable?
I am more interested in the subject now than ever after experiencing this poor start to this years outdoor grow.
Interested in any feedback.
