You do not need to water and feed every day.
You can CHOOSE to water every day. It’s just not necessary.
You should water according to your environmental conditions. One thing I will never stress enough is checking your PH. Verify going in, and verify going out. Once you get everything dialed in, you’ll do fine, but in the beginning I recommend it.
If you’re getting the bricks, you can charge it with nutrients, and get the ph dialed in before a plant goes in it.
If it’s the ready to use brands, most are already buffered. Always read the label.
I feed any time the plants need water. I’m watering/feeding once a week. I have no perlite mixed in, but you can mix some in. I have one container with a lot of perlite mixed in, and it needs watering a little more often. But it still does well.
If I missed something let me know, I’m happy to help.
