Free, practical, no-fluff education. Beginner primers, pump guides, nutrient charts, troubleshooting, videos, and downloadable PDFs. The exact knowledge I'd give a friend buying their first pump.
If you've never grown a single thing in your life, start here. Twelve sections, plain language, all the things I wish someone had told me before I burned through three pumps and a hardwood floor.
Read the primer →Wattage, flow rate, head height, and IPX rating — explained in plain English with our 3-step formula for any tower height.
EC and pH targets for the 12 crops most growers ask about. Lettuce to strawberries. Print it and tape it next to your tower.
Symptom → cause → fix. The 9 most common things that go wrong in week 2-4 and how to spot them early.
Lettuce, basil, mint, kale, strawberries. Why these five, why in that order, what to expect each week.
Wall counts, layer height, infill, nozzle temp. The exact Cura/PrusaSlicer settings I use for every tower part.
What they actually measure, why they matter, how to test them, and the ranges that work for every common crop.
Semester-long lesson plan, materials list, age-appropriate activities, and bulk pricing for schools and homeschool co-ops.
Why it shows up, how to prevent it, and the three things you shouldn't do (that the internet keeps telling people to do).
How to pick where to put your tower based on light, temperature, and the crop you want to grow. Plus a window-light test you can do today.
Match pump wattage to tower height. Smaller towers don't need bigger pumps — they just waste energy and stress the seals.
Ultra-quiet pump for tabletop and small towers. CE certified, double insulated, 1-year warranty. Won't waste power on a system that doesn't need it.
The all-rounder I ship with every standard kit. Quiet, reliable, plenty of head height for any tower up to standard kitchen-counter height.
For tall towers, premium builds, and commercial systems where you need the extra flow rate. Slightly louder, much stronger.
The single most useful chart in hydroponics. Print it. Tape it next to your tower. Adjust nutrient mix to match.
