Hydroponic Fun! How.

I've been learning a thing or two about how to take advantage of hydroponic gardening, without a full hydroponic rig. This system works for a simple, low-maintenance (not maintenance free) hydroponic system.

(I'll document WHY I'm doing this in another post.)

You'll need:

• Hydroponics Net Cups. I use a 2" size.

• A (plastic?) container with a lid. (More on this in a minute.)

• Spray paint (dark-ish) to make the container opaque.

• Rock wool cubes that fit the cups.

• A hole saw that fits the cups size you're using. 

• Hydroponic nutrients. (More on this later.)

Here’s how I did it. (The pictures show a lot of it, but probably not every step. You can figure it out.)

1.       Gather your lidded containers. These need to be opaque (to keep algae from growing in the nutrient solution), so paint them if you need to. Have fun with the paint if you like. The plants won’t care.

2.       Guy your supplies: You’ll need the net cups and the paint sooner than the rock wool.

3.       Use the hole saw that fits your net cups and cut a hole in the lids for the net cups to fit comfortably into. (Or cut them first and paint them later, if you like them prettier.)

4.       Mix your hydroponic nutrients according to their directions. Fill the containers up to the bottom of the net cup.

5.       I generally cut out the center of the bottom of the net cup, so that the seedling’s root will fit through easily, and also so that if/when I decide to plant these in the garden, I can get the roots out.

6.       Cut your rock wool cubes to fit the net cup if necessary. Slice it open. Nestle the seedling in the rock wool. Put this into the net cup, with the roots dangling below the net cup.

7.       Put the lid with the hole on the container. Stick the net cup / rock wool / seedling into the hole prepared for it. Ensure that the roots are dangling in the nutrient solution. Set them in a well-lighted place. 

8.    Check the levels of the nutrient fluid every week or two. You'll want to keep it up to the bottom of the net cup. If it develops funny colors, pour it out and replace it with fresh nutrients.

9.       Congratulate yourself on successfully starting hydroponic gardening.

A word about the nutrient solution:   Starter nutrition is sometimes different from Ongoing nutrition. The seedlings need a gentler solution, a different solution, and it will take care of the plants from seedlings (or cuttings, if you’re cloning) until they’re six or eight inches tall. At that point, you’ll probably want to graduate to the more mature nutrient solution.
