The technique is to
OSRS gold use the graph for 180 days and see what bounces constantly between two points and buy and sell before they reach them, it takes some time, but with practice it is possible to make amazing profits of about 1-2 million everyday...do some slayering or woodcutting at the same time so you don't waste time.
Herb running (in definition) is running between the various herb patches typically in the most time efficent way possible. It takes some time for people to develop the proper route between the one in the area of the swamp (forget that name) as well as the one at draynor manor as well as the one in the north of ardy, the one located in Catherby, and (if the quest has been completed) the patch that is located in Trollheim.
The aim should be to grow (usually) the most profitable herb seed that can yield the most cash when it's harvested. I'm not entirely sure about what is the ideal starting point and even the current pricing. However, I would probably not recommend you to start with your level until you unlock the other herb options.
Doing Fairytale Part 1 is an advantage since the secateurs increase the quantity of herbs that are collected. A good option for those looking to perform some herb-based runs in the near future is to purchase the Herb Scroll that comes from Dungeoneering in order to provide some possible "money back" if you are lucky. Additionally, playing Ghosts Ahoy! will aid you by providing the ectophile to make it easy to connection to the swamp patch. If you complete the lumbridge/draynor steps, it will provide you with an easy teleportation into the draynor patch.
When farming, you should make sure to use supercompost every time. Particularly when trying to make money from herbing. To clear up any confusion, you can't pay a farmer to look after your plants. You can just pay him to supervise the plots of vegetables and
cheap RS gold fruits inside the allotment.
