Hydroponic Float System

This is a completely passive hydroponic float system suitable for fast growing crops in cool weather

Here's a List of What You'll Need

a container
a piece of 1.5 to 2" sheet styrofoam cut to fit your container
a 2.5" hole saw
foam cups
Jiffy peat pellets
water
nutrients
seeds

Drill Holes Through the Styrofoam

you'll probably have to drill through from both sides. I made a template for my hole spacing

Now Prep Your Cups

Tear a couple holes in each cup and them place them in the frame, they need to stick through no more than a quarter of an inch

Mx Up Your Nutrient Mixture

either use a good hydroponic nutrient OR two teaspoons of miracle gro + a teaspoon of epsom salt per a gallon OR two teaspoons of peter's 20-20-20 per gallon.

Finally Put It Alltogether

pour the nutrient solution into your container, place the foam in the solution, place the cups in the holes in the foam and drop the long forgotten peat pellets in the cups, wait an hour or so for the pellets to swell up and sprinkle your seed on top of them and you're done.

Yield can be improved by the addition of an airstone and pump, but then you lose the convienience of a purley passive system.
