The Greenfingers aura prevents Farming crops from becoming diseased and provides a 3% chance of increased crop yield. The cost for this aura is 5,000 Membership Loyalty Points. The activation time is 20 minutes, and the recharge time is one hour.
Note that crops have the possibility of becoming diseased at the end of each growing cycle. The number and length of growing cycles varies with each crop. For example, herbs grow in 4 cycles of 20 minutes each, providing at least 4 opportunities for the crop to become diseased. Therefore, this aura can prevent disease in one of those cycles for each crop, but cannot prevent disease completely. It is not possible to pay a farmer to look after your trees while the aura is active. Trees planted using the aura can still become diseased. Patches that cannot be protected from disease by a gardener will be protected by the aura and will also say "A nearby gardener is looking after this patch for you" despite the fact that the patch cannot be looked after by a gardener.
The 3% extra yield does not give any experience. Getting an extra yield gives the message "Your aura allows you to recover an additional crop" in the chatbox. The extra crop will apply to herbs as well.
Based on player reports, there is an unconfirmed rumour that when the aura is used, patches treated with supercompost behave as though treated with compost or untreated altogether. Farming runs are said to have an overall lower yield than when supercomposted despite the possibility of harvesting extra crop. [source needed]
