Soaking this last batch of Cajun Jewel okra seeds, I noticed something strange. Some of the seeds floated on the top and some sunk to the bottom. As many times as I have planted okra, I couldnt remember if I had ever seen this before.

It is possible this happens every time and I have never paid attention before. Honestly soaking the seeds is usually one of those "Oh Crap" things you remember just before you go to bed. You are in your jammies, turning out the lights and locking up the house when you remember that you were planning on starting those okra plants the next day. So the standard practice is usually to find the seeds, dump them in a glass of water and go to bed without giving it another thought until I am ready to plant them the next day.
This time I remembered so far in advance that I paid attention to what I was doing when I popped the seeds in the glass. Immediately I noticed floaters and sinkers.
I had a theory about floaters and sinkers. I decided that the floaters didnt have much to get them started and that they would probably not germinate at all. I hypothesized the sinkers were better seed and would have a higher germination rate and would grow faster.
So, the next day I carefully separated the sinkers from the floaters. The floaters went in one starter flat and the sinkers went in another starter flat. They were placed in the same area so that they would receive the same amount of water and sun.
I planted them on Thursday afternoon and as you can see that by Sunday morning there was a definite difference in the germination between the floaters and sinkers. The floaters were sprouting away and the sinkers not so much.

I waited until Tuesday to check on them again. At that point, the floaters and sinkers were the same size!!!!
So, the sinkers germinated quickly, but once germinated didnt grow up any faster than the slower germinating floaters.

Unless you are in a really short growing season and you need those extra two days, there is no difference between your floaters and sinkers, except that some float and some sink.
I transplanted both floaters and sinkers into flood and drain grow beds. I have one bed filled with lava rock and the other filled with hydroton. I also set a couple of floaters and sinkers in a DWC raft. I also put one each floater and sinker in soil.
Since transplanted on Saturday, floaters and sinkers in the lava rock have produced their first true leaves. The floaters and sinkers in the hydroton and the DWC raft have not produced true leaves yet.
As you can see in the photos I took today (Monday), in the lava rock grow bed, there is no difference between a floater and sinker.

So, dont throw out your floaters.
Stay tuned for updates during the growing season.
