Flex Farm Assembly & Grow Guides
- Flex Farm Assembly ManualAssemble your Flex Farm: casters and tanks, drain tubing, pump, then 8 root chambers and 32 panels, the drip lines, and the Light Tower.
- Getting Started with Your Flex FarmStart your new Flex Farm: read the safety notes, gather supplies, fill the tanks halfway, plug unused spaces, run the pump 24/7, and flush the drip lines.
- How to Plant Seeds for Your Flex FarmPlant Flex Farm seeds in rockwool: soak the flat in cold water, drain it, put one pelleted seed in each hole, and cover it. Most sprout in about 2 days.
- How to Check and Adjust Flex Farm Nutrients and pHCheck Flex Farm pH and nutrients weekly. Aim for pH 6.0 (yellow) and nutrients 700 ppm above your plain-water reading, adding A and B in equal parts.
- How to Transplant Seedlings into Your Flex FarmTransplant seedlings into your Flex Farm once they sprout above the rockwool. Choose a grid or full pattern, insert cubes, and plug every empty space.
- How to Harvest Your Flex FarmHarvest Flex Farm lettuce when leaves meet and hide the white panel, about 21 to 28 days. Pull the plant, remove roots and rockwool, and refrigerate.
- How to Clean Your Flex Farm After HarvestAfter every Flex Farm harvest, brush and flush the drip lines, wipe panels and root chambers with 3% hydrogen peroxide, and clear debris from the tanks.
- How to Refresh the Water in Your Flex FarmRefresh your Flex Farm water every 1 to 6 months, based on your tap water's TDS. Drain the tanks, clean the pump filter, and refill the tanks half full.
- Weekly Flex Farm Maintenance ChecklistEach week, check your Flex Farm for debris and drip line flow, keep the tanks about half full, and test pH and nutrients at least once.
- How to Deep Clean and Shut Down Your Flex FarmDeep clean your Flex Farm every 6 months: purge the drip lines, drain the tanks, clean the pump and screens, and wipe parts with 3% hydrogen peroxide.
Flex Farm Troubleshooting
- How to Fix Poor Water Flow in Your Flex FarmFix poor Flex Farm water flow: keep both tanks at least half full, seat the pump at the back of the left tank, open the valve, and flush the drip lines.
- How to Install the Flex Farm Light Tower Height Adjustment KitInstall the Light Tower Height Adjustment Kit in 5 to 10 minutes: swap the four baseplate bumpers for taller ones so your Flex Farm tank lid closes fully.
- Flex Farm Light Tower Not Turning On or FlickeringIf your Flex Farm Light Tower flickers or will not turn on, water in the LED plugs has likely tripped its GFCI. Unplug the LEDs and dry them 24 hours.
- How to Prevent Algae and Calcium Buildup on Your Flex FarmAlgae grows where Flex Farm nutrient water meets light, and calcium builds up over time. Seat rockwool flush, plug empty spaces, and flush drip lines.
- Uneven Left & Right Flex Farm Tank LevelsFlex Farm tanks within 1 to 2 inches of each other are normal. If the right tank is 3+ inches higher, debris is likely blocking the connecting tubing.
- How to Get Rid of Powdery Mildew and Mold in Your Flex FarmWhite powder on Flex Farm plants is likely powdery mildew; fuzzy growth on rockwool may be mold. Wipe rockwool with 3% hydrogen peroxide and trim leaves.
- TDS Meter TroubleshootingIf your Flex Farm TDS meter will not turn on or reads wrong, replace its batteries (model 357A or L1154) first. A small x10 on the screen means multiply by 10.
- Why Do My Flex Farm Plants Look Unhealthy?Yellow, spotted, or tip-burned Flex Farm plants? Check the light timer, pH, nutrients, water age, humidity, and airflow, then feed A and B at a 1:1 ratio.
