Wrapped in a fun, 3D game-like environment is a sophisticated learning platform that navigates through the complexity of the marijuana grow process with elegance and simplicity. In this unique app people can experience the art of growing in a realistic way without a large investment in equipment or classes.

You can manage light, temperature, humidity, water levels, nutrients and pH levels to produce a unique plant each time. During the grow process, you have the ability to rotate and zoom to examine their plant in high resolution detail.

Along the way useful tips and educational information are available to guide and inform. When a successful plant is grown, you can keep a mother plant and crossbreed to capture great genetics, perfect a grow, experiment with technique and share photos of your plant.


• Developed by real growers using accurate scientific data.

• Each cannabis plant is unique and the outcomes are directly related to how you care for the plant.

• Like a Virtual Pet your plant will remind you to take care of it daily.

• Hands on learning for those that want to grow or just want to learn the basics for new career opportunities.


Accurate model of a Deep Water Culture (DWC) hydroponic system - an excellent method for beginners and experts alike providing ease of setup and maintenance, fault tolerance, and its ability to grow big plants, and big potent medicinal buds, fast.


All aspects of how a plant looks and grows are controlled by the genetic information. Each seed variety has its own genetic factors producing unique, one-of-a-kind plants.. Taking a mother plant captures the genetics of the particular seed, so clones grown from it will have the identical characteristics. The genetic possibilities are endless!


For Buds: quantity, shape, size, bracts, color, sugar leaf quantity, trich coverage, aroma, taste, effect, THC and CBD levels.
For Leaves: number of fronds, thickness, length, angular deviation, propensity to purple as plant matures.
For Stems: thickness, width and height, propensity to branch, length of stretch phase, speed of growth, propensity to stretch for light, feeding requirements and tolerances for all macro and micro nutrients, damage rates, branch angles and more.


simLeaf uses the Metal Framework for next level performance and capability in a true 3D environment.

Fun and informative...

Enjoying this so far. A couple of things I noticed that could be fixed. First, the humidity value in the statistics graph seems to be following the temperature scale. Second, there is no explanation for the ripening percent, flushing or sugar values. Also, the score HISTORY doesn’t make sense as it doesn’t persist from grow to grow. That would be an awesome feature though as there’s no history of past grows once you leave that screen. As far as Rocket mode, which is totally worth the in app purchase, it’s not clear whether temperature and humidity, etc., in addition to the feeding, is adjusted automatically. I wonder, because the Rocket grows seem to come out with low scores. All in all, a nice combination of gameplay and learning.

Awesome app

Love the app so far. One suggestion for improvement tho. Give us the ability to type in exact numbers for the nutrients (1ml vs 7 and so on). Using the slider on the smaller iphones (the non pluses) like mine can be really difficult when trying to give an exact amount of nutrients. It ends up wasting a decent amount of time trying to get the number to not change when lifting my finger up from adjusting the amount of nutrients to give the plant.

Gunna be honest, as a daily smoker for a year now and someone who wants to try growing weed without any of the financial setbacks, I was very excited about this game. I played it long enough to grow a couple plants and both yielded over 6 pounds. I think that is incredibly unrealistic. Then agian, I don’t know a whole lot about the marijuana plant itself.

Either way. The last two times I’ve tried to play, it’s crashed on me while skipping days.

We have not seen that issue with the yields before. Please send a screenshot to
