We look at the first iteration of growing tomato plants in DayZ Standalone and have a look at the mechanics behind this feature.
Step by Step Horticulture Guide
Step 1: Gather Your Supplies
You’ll need 4 things to begin tomato harvesting
EDIT: Apparently you can plant tomatoes without lime. Lime is not necessary, but it is a huge accelerant that cuts the growth time nearly in half. As such, I would still recommend taking a few minutes to look around for lime – it seems very easy to find currently.
Step 2: Dig
Use your shovel or hoe to dig out the greenhouse. Looking at the dirt should give you the digging option.
Step 3: Fertilize
Step 4: Plant
Put the tomato seeds in your hands, and look at the ground inside the greenhouse. A option should pop up allowing you to plant the seeds
Step 5: Wait
Stages of Growth: Stage 1
As far as I can tell, there are 4 stages of tomato plant growth. This is the 1st stage, where it begins to take hold.
Stages of Growth: Stage 2
Stages of Growth: Stage 3
Stages of Growth: Stage 4
Step 6: Harvest
Step 7: Enjoy!
Considering how food may become more scarce in future updates, I can certainly see farming being a viable food source.
Not counting gathering the supplies (which took <5 minutes) this entire process of digging, fertilizing, planting, growing, and harvesting took roughly 10+ minutes. The exact time for the plant to grow to harvestable state was 8:12 when I timed it. Every stage of growth took just over 2 minutes to complete. I noticed that the times I got were slightly different than the times Agathor got in his Wobo video. I timed mine exactly with a stopwatch, and I'm assuming he did something similar. This suggests there might be variables that influence - in small ways - how long the plant takes to grow. This is yet to be confirmed, it's simply a hunch because of the time differences between his tests vs my tests. As an extra note, many people (myself included initially) have been concerned about how unrealistic growth time is, and have expressed a desire to have much much longer growth times. While I 100% agree with that, and I would like to see a more realistic farming method in the future once everything is ironed out, I do have a plausible explanation for why it takes so little time. Considering it's on Exp right now, which is meant for no other purpose than to test features, my guess is that they made it so short simply because they wanted people to test it as much as possible as fast as possible. I do not expect in any way this to be near the time that it will take to grow tomatoes in the future - it just takes this amount of time now because they want to test it.
