HOw to start of growtopia (best way)

First you need a small lock.than place it at your world,than you need at least 10 rock seeds and 10 dirt seeds
     Than once you combine it it will turn to a grass tree,
Once you break all 10 trees you will get the block

Grass are easy to drop seeds,so all you need to do is to break the blocks than you will get more seeds,than plant it than keep breaking it until you have 200 seeds.it will only took around 15 minutes
 to get 200 seeds
Than you sell it in a trade world,world example:trade,traded,sell,tradeg,etc
Sell it 200 for 1 world lock or what they usually say wl than place the wls in your world,than repeat the part again until you have 4 wl total(include your world).than you go to SONGTOPIA where it's free to copy songs and special for trading song notes.
you will buy those piano notes 40-50/wl buy 150 of them,than you will break those notes and get the seeds,so all you need to do is to keep farming(planting and breaking to get more) it,than after you get 400 of them sell 300 of it with a price 50/wl at SONGTOPIA and keep 100 of it,so you can continue the farming it.if you farm it 2x a day you will get around 5wl and if you farming it more than 2x a day you will get more than 5wl(this is the most affective way to start of growtopia)
