I know i love the little sponges and holders like your link.
Don't forget your container will need net cups. https://www.amazon.com/Hydroponic-Plastic-Slotted-Nursery-Hydroponics/dp/B08CGVL9FW/ref=sr_1_5?crid=3RUX6R39QBSRV&keywords=net+cups&qid=1672436220&sprefix=net+cups%2Caps%2C124&sr=8-5
unless you get the sponge kit and drill small holes to fit the small white holders.
I can so I have a bunch of mason jars. But I also use it because I drilled 3 inch and 2 inch holes in my large tub. If I want to use one of my sponge white holders I can just use the black plastic ring to hold it.
Don't forget the toppers for 5 gallon buckets either.
I do the Kratky that one of the previous posters was talking about. It's great and no pump or air needed. I also have two fake aerogarden that I often use to start seeds for indoor or outdoor.
I'm a total newbie to hydroponics (2 months in) but I love it. I have gardened for a long time.
Start with lettuce if you like salads. Or Basil. These are some of the easiest things to grow and they grow fast so fun. I also have tomato (orange hat which stays very small). Tomato, black cherry which gets way too big but I knew that it would be a monster when I planted it. cucumber, jalapeno, red pepper, Yod Fah (a broccoli raab), radish, celery, basil, oregano, peppermint, majoram, kholrabi, 5 different lettuces, some sweet potato starts for spring, eggplant start, a pixie cabbage (only 5 in head).
Since I'm only 2 months in I have only taken, herbs, lettuce, celery leaves, radish and cucumber out of my hydro stuff so far. But tomorrow is Yod Fah stir fry and I have flowers on both peppers and tomatoes flowers.
About to start a new batch of seeds for lettuce and outdoor plantings.
Good luck you can do it!
