drip watering system

I can vouch for Netafim Halos as emitters. Keep it simple. You might be able to pinch a few pennies grabbing a small aquarium pump and designing your own. Automating it will be as simple as timer of choice and a few runs of volume versus time relative to your pot sizes. Have fun with it.

Its easier to make your own to suit your grow. That's what I do. Bucket, water pump, irrigation pipe, manifold, stop end, drippers. Most expensive part being water pump at around £25-£30. Your local Hydro store will most likely have everything you need.

I've been hearing good things about the Spider Farmer system.. oh wait, you have way more plants than that system supports (max 4). Unless you're willing to purchase two sets? 😅😅😅
