Hmm....that sounds exactly like what we're talking about. Only two things I can think of then are these:
- do you seal that plastic baggie you put it in? Probably don't wanna do that if so.
The baggies have been sealed. I didn't know that they were supposed to be open.
- where are you getting your seeds from? I can suggest several non-sponsored seed places, in the US, that I've used successfully if you think that might be an issue. Message me, I don't wanna step on any sponsor's toes (if you want).
- All of the seeds we bought were bought from reputable seed shops except for my latest purchase from a new, Canadian seed shop that I wanted to support.
Also, I disagree with VG on that one point. Always plant stem down seed coat up. That's the way the plant is going to sort itself out no matter how you plant it, so why would you want to make it more difficult on the seedling by planting it any way but that? That's my philosophy anyway, not saying VG is wrong, just that we disagree.
I only tried it sideways since nothing else had worked.
Azi shared this pic with me recently and it looks like plant stem up is how I'm supposed to plant.
Yep, I don't poke into the water either. I actually thought the idea, besides to swell the seed with water, was that if you float it overnight and it's on the bottom of the glass in the morning, or if it immediately sinks when gently pushed to the bottom, then that seed is viable. Those that won't sink are not. Not sure if it's true, never tried to plant one that didn't sink. But I'm with you on that.
Most of the seeds I've planted this year haven't sunk and they turned out fine.
I've considered the heat mat, I'm sure it's a good idea. But for me given the outdoors here I just let the tent stay open in seedling and the plants stay at about 80-83 degrees and 70% Rh, ie, the outdoor environment. They love it. But still, a mat would make things better and no open tent. Nice.
The viable seeds sinking is an old wives tale. I've not noticed any difference at all between floaters and sinkers. And they crack just fine floating on the surface.
Actually, the paper towel method is much closer to nature. The seed is nestled in a moist, but not overly wet, environment with better access to air presuming you don't seal the bag. When I do it that way I soak the paper towel then hold it up by a corner to let the excess water drip off. Then I fold it a few times, lay the seed on top and slide it into a baggie. Then I'll lay it it in a dark and warm place until it springs a tail. With this method you can easily see when it sprouts since the seed is up against the clear bag.
Much easier and faster to check than digging the towel out of the bag and trying to peel the sheets apart and then putting it all back together.
I also don't ever handle the seed, but rather use pair of tweezers to keep diseases off.
And finally, I use a bit of fresh worm castings diluted in water. The worm castings are known to ward off 'damping off' disease. I use the water to soak the seed and then pour it over the soil to inoculate it.
HG,
Sounds like getting the seed to crack and throw a tail is working so that suggests your issues come when you plant them.
The two things that come to mind are your mix and environment.
For environment make sure you have moist and warm temps. I don't know what a PVR is, but I assume it throws some heat? But not too much heat so as not to cook them?
The PVR is our satellite TV's recording device. It's nice and warm on top and it has gotten me taproots.
Also, I don't use Promix, but seem to remember that is peat based, so maybe pH is an issue? Maybe try a simple inert seed starting mix, at least for the top few inches of your cup where the seed will initially be.
And the lightly water each day as others have stated.
After I plant the seed, the solo cup goes on the baker's rack and is approximately 12" from the light. I don't currently use a heat pad but I could if it was deemed necessary since we do have one. Other possibilities include doming the cups or try starting the seeds in hempy.
I just don't know why it's so hard now. I didn't have any problems with the 34 other seeds I've planted since I started growing.
