Just have some patience.
I meant that if the spore print was small because the caps of this strain are just small, you can expect less spores so I would recommend less spore syringe duplication. I really do hope you used sterile water and a way to prevent contaminations from falling into the water as you prepared the syringes. Common syringes are 10 ccs each, a superwild guess would be that you can stretch it to two syringes of 10, making 20 total but I would play it safe and not make more from them. When you dilute, remember to also use the sterile procedures. You can add lube by the way, to prevent the spores from sticking to the side of the syringe after they have been laying down for a while. Always gently shake the syringes before using them otherwise I'm not surprised if there are only few spores in there. They are so very very tiny that you generally only see a little blackish-purplish hue to the water anyway and not that much more unless they are quite concentrated.
Two days is nothing, just give it time.
Tampanensis are not Cubenses (plural of Cubensis), no. Like I said they are usually used to produce truffles which indeed like you say tend to be on the milder side of the mushroom experience spectrum, the Azurescens and Cyanescens being on the very strong side. Cubensis cover the broad middle ground of the spectrum, they are by and large the most common ones and usually the standard against which all psilocybes are measured.
Tampanensis can also be made to fruit but I cannot give you an expectation of how potent they would be, I guess roughly like P. Mexicana or somewhat like Cubensis or just a little less potent like the Tampanensis truffles. Use the mushroom dose calculator I mention later on, you can find it on the internet.
On the one hand it's a fine idea that you want to start with the milder types but on the other hand you should not really expect to be able to trip half-assed because you do not feel ready for a real mushroom trip. I think you would do well to decide to generally trip on mushrooms or decide against it and not look for a middle ground. BUT you can indeed approach it carefully by starting with a low dose and working your way up on other occasions.
I understand if you are confused now, and don't know whether to let them produce truffles or fruits (the mushrooms themselves). You seem in a hurry, are you? If so, maybe these Tampanenses are not really the way to go for you and you could consider this batch a side-project and shelve the jars in the dark to make truffles for the long term. Then order actual Cubensis spores, and choose your preferred property.
South-American Cubensis substrains like Cambodians or Equadorians tend to colonize faster and stronger, perhaps because of the 'law of the jungle' that pushes them on. Some substrains have a tendency to produce only few mushrooms but very large ones and others produce a large quantity of smaller ones. For a beginner it couldn't hurt to choose a strong substrain that is one of the most common ones like perhaps B+ or PF but in all honesty I don't think that the differences are big enough to make THAT much of a real difference. The way you cultivate them is much more important.
I suppose you perhaps do not want to start over and see where these Tampanenses get you with fruits, well then just have some patience and get them to make mushrooms. Research how you can push Tampanensis to do that instead of staying in-soil making sclerotia. It shouldn't be hard, probably the biggest factor is just to give them access to a little light instead of darkness. Not a lot of light like you do with plants. Just a signal that tells them: this way is up and above-ground.
Then use the mushroom dose calculator I think they have over there on the Shroomery or some similar site to calculate what kind of dose is equal to a certain dose of Cubensis. Check our Beginners FAQ to read how you can find the First Time Tripper thread and First Time Shrooming thread on some opinions on how to pick your initial dose. If you are apprehensive, that could be something like no more than half a standard dose.
And another thing: when you harvest your mushrooms, start drying them immediately unless you plan on eating all of them within a very short period of time. In that case the fridge is okay. But in all other cases just suspend them on something like a plastic mesh (like mesh that keeps mosquitos out of windows) so that air can touch them everywhere. Put them in a place then, that is not so cold that they will dry too slowly but also not so hot that they will degrade. A draft is also vital, air has to flow or blow over them to refresh the air that absorbs water from them.
I recommend after that, that you put them in a tight box or container that has dessicant in it as well to draw the last of the water out and make them what is called "cracker dry".
