Is this a 20g Long or 20 litre? How many goldys? What type of goldys? Whats your filtration?

Sadly, you should preferably only keep one goldy in there once full grown.

Yeah, it may take a year to see substantial growth but by then you will need at least a 55g tank to keep all 4

Do you have an API Master Test Kit?

Okay well ill still advise you to get one. How much water do you change per week?

Just because you have high filtration and do weekly water changes, doesn't mean you can keep that many goldfish in a 20 gallon tank. It is only suitable for a single fancy goldfish.

Okay that's good to hear. Lets look at it like this. 4 goldfish make x ammount of nitrates. A good nitrate level is 5 to 10. Say your goldys make 60ppm of nitrates per week and your changing 50% of the water, thats taking 30ppm of nitrates out and your left with 30ppm. So next week you habe 90ppm because you were stuck with 30ppm from the week before. See where im getting at? An API Freshwater Master Test Kit can help you see the actual ammount and help you better change water quicker when needed. If I were you, id be doing x2 50% water changes a week in a goldy tank just because of their massive bio-load

It's an accepted rule of thumb to keep 1 fancy goldfish in a 30g tank with an extra fish for every 10 gallons. Even with a weekly 50% water change I would highly suggest buying at least a nitrate test kit for an overstocked goldy tank.

They should get to about 8 inches when fully grown *IF* they have proper care and nutrition.... I honestly wouldn't keep four 8" fish in a 20 long. I personally wouldn't even keep one 8" goldie in a 20 long.
I see that you will be moving them, but how do you know they have suitable water quality if you don't test the water?

I agree with the above two posts.
Again, they will be move to a pond. It would be rather stupid to try to fit full grown goldfish in a low 20 gallon. That rule of thumb is based on a required filter. Some Nitrates turn into plant food. Thats how I can keep 4 fancy in a 20 gallon.
P.S. this is experienced based, not something you read off the internet. I know what I am doing. Im looking for more information on success in planting. Not info for noobs to the hobby.

How do you know your nitrates without a test kit?
It would take waaaaay too many plants to lower nitrates in a goldfish tank then what you think it takes. Thats why most plantes tanks are small fish with tiny bio-loads and shrimp because there is virtually no bio-load

Just because it looks clean doesnt mean it is. Looks are very deceiving. A tesr kit will show the truth and thats the only way to know for sure. Its only 15 bucks online. Not a bad investment either as it does last for a few years
