Questions about optimizing plant growth

I do keep somewhat heavily planted tanks with no Co2/ferts (dirt though). Growth is slow but i can keep things like Mayacas, swords, blue hygros, the kind of stuff you dont normally see in low-tech tanks.
However, i do want to upgrade to high tech. Pretty soon im upgrading to a 2 ft 2 bulb F14T5 grow light for my 30g. Also, later than that, a fluval Co2 kit (cheaper, hopefully not for a bad reason). Also on that list of upgrades is dosing actual ferts.

Can anyone make suggestions on a dosing method, best place to buy raw dosing elements, and a source for Co2 to refill?

Sometimes you just need a little more cake.

Maybe there's a different kit. I thought the Fluval took disposable cartridges. It can get pretty expensive to inject that way since you'll typically pay well over $100 lb for CO2 from Fluval.

Much better off buying a larger tank and setting it up right. The prices they charge people for this tiny stuff are crazy! I pay 24 dollars per year for co2 for all of my displays. At Fluvals price my one tank of co2 would cost 2,000 dollars! This hobby is beautiful and fun if you dont let it lay waste to your savings/income. If committed to the set up Id spend the extra up front and get a real co2 system that will save you thousands of dollars in the long run.

Ill look into reading that article about ferts. Ive never really dosed anything other than seachem ferts. This is all new to me. For a fluval Co2 kit, i was planning to use this one: https://www.bigalspets.com/fluval-mi...UaAuqaEALw_wcB on a 30g, on higher setting, like 2-3 bps.

how does the cartridge system work? do i hve to get new cartridges very often?

Just say no. Read the comments above.

Yes, you will need to replace cartridges when they run empty. The 22g replacement cartriges are $15 per 3.

I used the 88g model on a 12g long, about $40 / month in cartriges. There is no way to turn that sucker off at night except by closing the needle valve by hand. Sure, you can splice a solenoid in, but that's just more good money after bad.

If you really really need / want co2 (and I bet you dont, not when you are starting out), bite the bullet and do it right. And that's $250 - 400, to start.

im not exactly "starting out". Im starting out with high tech, if thats what you mean. I can do regular Co2, or DIY.

A 20 gram cartridge system on a 30 gallon tank will cost you a fortune in co2. You'll be replacing cartridges probably every 2 weeks. Definitely a big mistake to go that way. Personally you could have a working pressurized system for around $150 without question.

You can always start off with DIY CO2 to see the improvements it will bring to your aquarium. It should also help convince you that CO2 is definitely the way to go!

If you are going to do something do it right. Get the real deal and have a system that doesnt give you headaches/trouble. DIY co2 is not very consistent, takes more time, effort, and spending in the long run as well. As much as it is to set up a co2 system its far more expensive tinkering with place holders than to just set it up right the fiest time ime.
