I've got a bottle of Great White I've never used, so I think I may give that a go as well.
Wouldn't a dome eliminate the 5x a day watering?
I add new myco at every opportunity. Especially in seedling stage. I have heard Great White is good stuff.
A dome may help but I'm not a fan of still air unless its nescessary.
I find seedlings from under domes tend to be leggier than those that aren't.
I also turn the humidity up to 65% for seedling germination. I like repeated sprayings to simulate spring weather.
The dome could very well cut down on sprayings though.
I spent a lot of time years back, struggling to get better seedlings and better success rates, and studied my way to this.
You can do it all with well rinsed pre-hydrated coco too tho, or peat pucks, and coco holds the moisture better if the peat thing is too much.
I think peat breathes better myself, but thats just an observation.
Try 1 seed just to see if its worth your effort. Actually, try germinating in your leaf mold
Now that is truly natures way
If you just plant your seed, take it to harvest, then plant another, without ever cloning, then a plant achieving its genetic potential is far less detrimental, as it will never pass its genes to the next generation.
I start every plant with the intention that it will be my favorite mother plant ever. I have had 2 very stellar phenos slip past me because I never cloned them, and stellar phenos are very very rare, so I put in the effort.
I also had low cloning success so studied up on that, and found that a successful cloning rate starts the day the mother plant pops from seed, so even tho I don't like the sprouting process, I love the sprouts, so I put in the effort.
But its a pain in the ass, did I mention that part?
Plants are very adaptable. Soil and stress have the ability to shape a plants dna very quickly, from generation to generation. Thats natures way too.
Its why you plant something, and a few seasons later it has spread and become very robust. It genetically adapted to its regular environment over only a few generations.
I don't want to mess with a seeds immune system as thats what actually oversee's its genetic future and shape. So again, I put in the effort.
I can't say with proof that peat is better, but I can say it greatly upped my sproutlings quality of life for their entire life, and cloning got way easier.
