Hydroponic farming, in the real world and in the game, is the practice of growing plants in water rather than in soil. This makes sense for the world of Probably Stolen; when you're living on a space station, dirt is going to be hard to find, so you need to find alternative ways to keep food production stable. Here's everything you need to know about getting started with and making a profit from hydroponic farming in Probably Stolen. How To Start Hydroponic Farming The hydroponic system in Probably Stolen, set up with a battery, three modules, water, and a Nutrifruit seed. You unlock hydroponic farming through the Retired Farmer upgrade in Joe Wild's network. This upgrade costs 350 credits and has a retired farmer come to your window the day after you buy it with a bunch of supplies to sell off including the hydroponic farming manual, a hydroponic system machine, seeds, water, and nutrient tablets. To grow things in the hydroponic system, you'll plant a seed, fill up the water, make sure the machine has power, and let it run overnight. Some seeds will require you to enhance the water supply with nutrient tablets, which change the mineral concentration, and others will require certain grades of water. What You Can Grow With Hydroponic Farming The hydroponic system now filled with Nutrifruit. A water purifier is also open. You can grow pretty much any seed from the get-go with a hydroponic system, though some will be harder than others to keep going. Fillerweed is the easiest plant to get and grow, requiring no specific water type outside of Ghostwater and no specific nutrients. It grows in one night and produces around five plants and one seed per harvest, meaning it's a perpetual crop if you need it to be. You can get a Fillerweed Hydroponic Module from Dr. Jackson; while it does yield an extra plant per harvest, it also means they stop producing seeds, so I wouldn't recommend it. Nutrifruit is also relatively easy to grow, also requiring no specific water type outside of Ghostwater and no specific nutrients, and it usually yields seven fruits after two nights of growth. Unfortunately, these never produce seeds, so you'll have to buy them to produce more. A Nutrifruit Hydroponic Module from Dr. Jackson adds one more fruit to each harvest. Kotton Fiber takes six nights to grow, and requires a little bit of mineral content in the water — about one nutrient tablet would work fine for this. This plant is susceptible to contamination, so try to use High-Quality water when possible. It produces 13 Kotton Fiber per harvest, which can be woven into fabric with an Auto Loom module from Dr. Jackson. They don't produce their own seeds, so you will need to buy them. Dream Caps are psychoactive mushrooms. This takes four nights to grow and needs around the same level of minerality as Kotton Fiber, though it's less sensitive to contamination so can take Basewater (I wouldn't use anything lower than that, though). It produces eight Dream Caps per harvest. These can be made into Dream Cap Extract, which is contraband or turned into Meal Caps, a legal food, with a Neutralizer module from Dr. Jackson. You can also grow Nightmare Caps from Dream Caps with the Dream Cap Nightmare Hydroponic Module from Dr. Jackson, which are high-level contraband. Coffee Beans are exactly what they sound like. They take three nights to grow, need the same growing conditions as Dream Caps, and produce eight beans per harvest. These beans can be turned into caffeine with the Chemistry machines, though this is a particularly complicated process. BloomBerries are a bush that you can get multiple harvests from. They need roughly the same conditions as Dream Caps and Coffee Beans, and take about two or three nights to start producing. You get six BloomBerries per harvest, which can be used to make BloomBerry Wine with the Winemaker upgrade from Joe Wild's network. They don't produce their own seeds, so you will need to buy them. Hydroreeds produce a filter you can use for water purification if you've got the Hydroreed Filter Hydroponic Module from Dr. Jackson. They're immensely hardy plants, needing little if any minerals and immune to contamination, so you can grow them with any water. They take three nights to grow and produce one filter per harvest and one seed. Where To Get Seeds And Supplies You'll get most of your seeds from the Retired Farmer, who visits every Friday. They'll also carry the hydroponic systems, nutrient tablets, and sometimes water, as well as the Hydroponic Farming Manual, Plant Analyzer, Aquascan, and various water purification items. You can get the hydroponic modules from them as well. After unlocking the Retired Farmer upgrade, Dr. Jackson will also carry hydroponics supplies in his shop. You can get any of the modules and machines from him, though he doesn't sell seeds. It's a good idea to plan your growing for the week around your intended supply runs. Stock up on everything you need on Friday when the Retired Farmer Comes by and supplement your supplies from Dr. Jackson as needed. Try to buy your modules and additional hydroponic systems from Jackson during his occasional sales at night for a better price. Where To Get Water A screenshot from Probably Stolen, showing the display case and a storage bay filled with water bottles, a water pitcher, and various water testing supplies alongside other miscellaneous inventory. One of the most consistent ways to get water for farming is to get the Water Trading upgrade from Joe Wild's network, which gives you a tap with unlimited Gutterflow water that you can access anytime. Stock up with a water pitcher with a filter and some purification tablets, or get a Water Purifier, and you're good to grow most things. You'll also then have excess water to sell, which is a bonus. If this is too expensive for you, you can also go for a Moisture Farm, which produces Ghostwater overnight for each of your farms, though you'll need several if you have several farms going. You can get one from the Retired Water Merchant or Dr. Jackson's shop. Whichever method you choose, you should probably also get a Bottle Printer to store up excess water for use later or sale.
