What is Reddit's opinion of Duda Energy Syringepk003 Industrial Syringes with 15G x 1-1/2" Blunt Tip Fill Needle and Plastic Cover, 3 mL (Pack of 10)?

Maybe. Seedlings are very vulnerable at this stage and when their vascular tissues lose turgor pressure due to low water input, they become extremely fragile. You'll want to be careful in how you water the ones that are laying on the soil. The ones just leaning over will probably be fine, but that one laying on the soil could easily be killed by watering. In this situation, I'd water using an industrial syringe. Good luck.

mix and match get new flavors have fun with it but if you want to empty it easily buy somthing like this https://www.amazon.com/Duda-Energy-Syringepk003-Industrial-Syringes/dp/B00DXPQIFU to pull it out of the tank and then pour your new stuff in

I use syringes and blunt-tipped Luer Lock needles for all sorts of stuff. I generally get them from an Amazon store called Duda Energy (I think they cater to people who make their own biodiesel.) Anyway, here's some 3ml syringes with 15g blunt needles, 10 for $8.95 and free shipping. They have bigger sizes too, but 3mL should work fine, and I think the 15g needles will be large enough to work with Titebond or another yellow wood glue (definitely if you thin it a little with water, but try without first.) I use 15g needles to suck up vegetable glycerin and that stuff is almost like honey.

Blunt tipped syringes of 3 - 5 ml work best. You can find a fair few around. Here's an Amazon link to something that would work and a Goulet link to something specifically for it.

I can't guarantee the glue and syringe method will work, but it's worth giving a shot first. The glue dries fast enough that you can do a couple bubbles, press them flat for an hour or two, and then check your progress. If that works, then keep at it.

You'll probably have to thin the glue: yellow wood glue (like Titebond) can be thinned with up to 5% water; anything more than that and the glue starts losing strength. 5% water should make it thin enough for syringe use though, and if you need to use a little more water it's probably not a big deal. This is veneer, not a structural joint, so it shouldn't matter too much if you weaken the glue a smidge.

I buy syringes from a seller on Amazon called Duda Energy. Here's a link to 3ml syringes with 15g needles (10 for $8.50), which should be perfect. 15g needles are big enough to deal with thinned wood glue, and the 3ml should hold plenty of glue so you won't need to refill it too much. I wouldn't suggest bigger syringes, just because they can be hard to draw liquid into, but smaller 1ml syringes would work fine. I also wouldn't use a needle smaller than 16g, but 14g-16g will be fine (remember, needle gauges get smaller as the gauge number increases.) I've bought a lot of stuff from Duda, but there are other sellers on Amazon and eBay too (just be aware that not all syringes come with needles.) You can reuse the needles and syringes as long as you wash the glue out with hot water before it dries up; they're also handy to have around in case you need to re-glue a headstock or some other major crack.

If you need a sharp/beveled needle, you can sharpen one of these pretty quick on a sharpening stone or 200 grit sandpaper. You probably won't find actual sharp needles very easily on Amazon (mostly because they're controlled in some states as drug paraphernalia), but blunt-tip ones should work fine. You'll also want an Xacto or other hobby knife, along with a few blades, to make a small slit in the bubble that you can slide the needle into.

I'd make a small slit in a bubble, slide a syringe in and fill it with a lot of glue, then press the bubble down really well. This will probably squeeze a bunch (if not most) of the glue back out, which you'll want to wipe up with a damp rag. Then put something flat and heavy on the bubble for at least an hour or two, to let the glue set up enough to hold the bubble in place. I'd just do a couple bubbles first as a test run to see if it's going to work well enough for you; as long as they're glued down, you can sand minor lumps flush. If the test run works, do the rest of the bubbles and then let it sit for a good 18-24 hours so the glue can fully dry before you get on with any refinishing.

Dissolving into candy doesn't sound like a good idea IMO. Maybe one of these empty tanks would work? Also, why not fill the syringe, cap it, and send it as-is?

Either way, you can get blunt-tip syringes pretty easily.
