How long each crop takes to grow

Every seed grows in a set number of stages, and each stage lasts one cycle of 5, 10, 20, 40, 80, 160, 320 or 640 minutes. The growth time below is the longest a crop can take. Because the first stage ends at the next tick, it is usually ready a little sooner, by up to one cycle.

How long do herbs take to grow?

Every herb, from guam to torstol, grows in four stages of 20 minutes: 1h 20m at most, and more than an hour, because the first stage ends at the next 20-minute tick. So a herb run every 80 minutes finds every patch grown. A herb patch cannot be protected by a farmer, but the patches at Troll Stronghold, Weiss and Harmony Island never catch disease, Hosidius stops with the easy Kourend & Kebos diary and the patch west of Civitas illa Fortis stops at 16,000 Glory. What a herb run pays is on the herb run calculator.

How long do trees take to grow?

Trees grow on the 40-minute cycle: an oak in 2h 40m, a willow in 4h, a maple in 5h 20m, a yew in 6h 5m and a magic tree in 8h. A yew's first stage lasts only 5 minutes, so it is 9 stages of 40 minutes after that. Every fruit tree takes six stages of 160 minutes, 16h, and then grows a new fruit every 40 minutes once picked. Hardwoods are the slowest: a teak takes 74h 40m, a mahogany, camphor or ironwood 85h 20m and a rosewood 106h 40m, the same as a redwood. A calquat takes 21h 20m, a celastrus 13h 20m, a crystal tree 8h and a spirit tree 64h. The experience a tree run is worth, and how many days a Farming goal takes, are on the Farming calculator.

How long do mushrooms, allotments and the other patches take?

A bittercap mushroom takes 4h, belladonna 5h 20m, a cactus 9h 20m and a potato cactus 1h 10m. Giant seaweed takes 40 min, a grape vine 35 min and each coral 2h 40m. Allotments take from 40 min for potatoes, onions, cabbages and tomatoes to 1h 20m for watermelons, every flower takes 20 min, hops from 40 min for barley to 1h 40m for cotton, and bushes from 1h 40m for redberries to 2h 40m for jangerberries, whiteberries and poison ivy.

The growth cycles

Each cycle ticks at fixed times in UTC, and every faster cycle ticks along with it, so every crop moves on together once every 640 minutes.

Finding your growth offset

Your ticks come up to 31 minutes earlier than those UTC times, and the gap stays the same each time you log in. To find it, note the time a slow crop such as a hardwood grows a stage and take it from the time that cycle ticks in UTC. A mahogany that grows at 10:28 UTC, where the 640-minute tick is at 10:40 on the first of its four days, means an offset of 12 minutes. Enter it in the panel and every window above becomes one time.

Does compost make crops grow faster?

No. Compost, supercompost and ultracompost cut the chance of disease by half, four fifths and nine tenths, and add to the harvest of allotments, hops, herbs, giant seaweed, celastrus and crystal trees, but a crop grows in the same number of stages whatever you use. They help a crop come in on time only because a diseased crop stops growing until it is cured, and dies if it is left. Crops cannot catch disease in their first stage or once they are grown. Paying the farmer, a grown flower beside an allotment or a disease-free patch takes the risk away, and the table above names the payment for each crop.

What else changes when a crop is ready?

A kronos plant in the anima patch gives every patch a chance to skip a stage at its next tick, so a crop can be ready sooner than shown; no rate for that chance is published. Attas raises the harvest, iasor lowers the chance of disease and the Farming cape raises the herbs a herb patch gives; of the three anima plants only kronos touches the stages. An anima plant is alive for eight 640-minute stages, from 74h 40m to 85h 20m, and its effect ends when it dies. The Hespori takes three 640-minute stages, up to 32h, and is then fought. Tithe Farm plants grow on the minigame's own timer, which the Tithe Farm calculator plans.
