Growing with Hydroponics

What is Hydroponics?

Hydroponics is a soilless growing method that suspends roots in nutrient water to achieve faster and cleaner growth without the mess of traditional soil-based gardening.  Using Aerators, misters or 1/4 inch space between the plant and the roots (as in the no-airstone Kratky Hydroponics method), plants typically grow faster with less root growth due to the readily available water and nutrients available in Hydroponics.  Compared to soil-based gardening, as nutrients are added to the water of hydroponic grow systems to maintain a healthier growth rate, plant produce is significantly enhanced and takes up in much smaller growing space than traditional soil-based gardening.

Another advantage to Hydroponics over traditional soil methods is the adaptability of Hydroponics to any given grow space.  Utilizing vertical grow tower units, grow shelving units, or fish-tank aquaponic grow top trays, one can easily adapt a Hydroponics grow system to fit any given container or grow space.

We hope you will enjoy the following videos as we discuss simple Hydroponics grow systems that we have developed and utilized in our own home-based Hydroponic Gardens, and we also provide tips for what vegetables grow best in what type of system.  Here we feature both an Ebb and Flow Garden Grow tower (where the water cycles in and out of the grow trays on a timer), a Deep Water Culture system (with roots suspended directly into the aerated nutrient water), as well as simple airstone-free Kratky grow trays which require nothing but nutrient water and lights to grow the small lettuce and herb plants to full-term.

Do you need PH & TDS Meters to Grow Simple Hydroponics?

Simple Hydroponics - Do You Need a PH & TDS Meter?

 

PH is the measurement of Acidity to Alkalinity on a logarithmic scale from 0-14.  A PH reading of 7.0 is considered neutral, whereas a PH of 6.0 is 10 times more acidic than 7.0, and a PH reading of 8.0 is 10 times more alkaline than a reading of 7.0 PH.  Temperatures and the amount of hydroponic nutrients in a solution affect PH readings in the water reserve. Thus, it is recommended that if you are going to test the PH of your solution, you do it after you add nutrients and not necessarily before as the nutrient content in a reserve directly affects PH.  Algae build-up in a reserve can cause PH to go up during the day as it consumes acidic compounds like carbon dioxide. Higher levels of phosphorus and nitrogen decrease PH while higher concentrations of calcium and potassium in a nutrient reserve drives PH up. When the PH level rises above 7.5, it can lead to iron deficiency in plants as the alkalinity of a high PH can block the ability of the plants to absorb iron.

Growing Microgreens in Hydroponics

Why Grow Microgreens

 

Microgreens are baby vegetables that are approximately 1 to 3 inches tall. They are often grown from a variety of seeds and provide a dense nutrient content that is greater than full grown vegetables because the vitamins and minerals within them are concentrated in these baby plants.  While Microgreens are similar to Sprouts, they differ from Sprouts because they are harvested 7 to 21 days after germination whereas Sprouts are usually harvested between 2 to 7 days with both their stems and roots which are considered edible before the true leaves appear.

Tomato Burn - Brown Curly Leaves

Tomato Burn Problems in Hydroponics

 

Tomato burn in Hydroponics occurs when your nutrient TDS is too high. It results in brown spots developing on Tomato Leaves, highlighted with curled tomato leaves. The sooner you recognize the signs of nutrient burn on your plants, the sooner you can respond by quickly changing your nutrient solution, or diluting it 50% or more. To help plants recover quickly from nutrient, it is best to let them recover in pure water for a few days or a light nutrient water-base for a couple of weeks. Aquaponics can also be a good way to nurse your burned tomatoes back to good health. Learn more about Fixing Hydroponic problems here.

Growing Hydroponic Tomatoes

How to Grow Hydroponic Tomatoes

 

Container gardening is a good way to grow tomatoes in a compact space, like on a porch or in a greenhouse, but one difficult task with growing tomatoes using the standard soil-based grow method is maintaining the proper water level for tomatoes as each mature plant can go through a gallon of water per day.  This is where utilizing a Deep Water Culture Hydroponic grow system with your container tomatoes can make all the difference in maximizing the yield you receive off of each tomato plant.  Not only can you more easily control the moisture levels in your Hydroponic grow system through the Deep Water Culture (DWC) method, but since the roots of your plants are suspended in an aerated nutrient reserve, you can more easily control the oxygen and nutrients supplied to your plants as well.

Creating DIY Hydroponic DWC Coffee Pots for Hydroponic Tomatoes

Creating DWC Coffee Pots & Transplanting Tomatoes

 

Deep Water Culture (DWC) Hydroponics is a method of growing plants in an aerated nutrient water reserve.  In this video, we show you a simple DIY method to turn a coffee pot into a small DWC Hydroponic reserve to start your plants. We also demonstrate how easy it is to transplant a small soil-based potted tomato plant into the DIY coffee pot Hydroponic system you can use to start your Hydroponic tomato plants indoors in the springtime for later planting into a larger DWC bucket system outdoors.

Starting and Transplanting Hydroponic Beans

Starting Beans in Hydroponics - Germinating and Transplanting Beans

 

Beans can be difficult to germinate in Aquaponics if overnight temperatures in the greenhouse are not able to be held between 70 and 80 degrees. We found that if we use a Parkseed 40-Cell Bio Dome Seed Starter Unit and fill it with 1-inch Hydroponic grow cubes, water and a heat mat, the sprout rate for our Bush Snap Beans increased from 30% to 90% in just 7 days. Now we use these Bio Domes to germinate all of our Hydroponic warm season plants.

Yellowing Hydroponic Leaves - A Sign of Nutrient Deficiency

 

 

A sign of nutrient imbalance in your Hydroponic Grow System is when the leaves on your plants begin to turn yellow. Because Hydroponic plants are completely dependent upon the nutrients you supply, it is important to recognize the signs of nutrient deficiency quickly so that you can correct it before too much irreparable damage is done to your plants.

Hydroponic Seedlings - Splitting Duplicate Plants

 

If you are looking for a way to increase the seed germination and plant coverage that you have within your hydroponic grow trays, you can try double seeding the hydroponic rockwool cubes in your grow system.  While this can be a good way to decrease the number of grow spots in your system that do not have plants, one problem that occurs is when you have two or more plants sprout within the same grow cube.  While most gardeners advise people to snip off the excess plants, I learned a way to save them.  View this video where you can learn how to split out your duplicate seedlings to be able to plant them in another Netpot grow spot in your hydroponic trays.

What Is Deep Water Culture Hydroponics?

Deep Water Culture is a method of growing plants by the root of the plants being suspended in aerated, nutrient enhanced water.  The advantage of the Deep Water Culture growing method over the traditional soil method is the fact that the root of the plants do not have to grow as large as they would in standard soil grow systems and can therefore grow in much smaller containers because the roots of the plants do not have to travel to find water.

How to Build Your Own 5-Tier Strawberry Hydroponic Grow Kit

Mr Stacky planters for growing hydroponic strawberries and other small vegetables are a  good way to conserve space in your home or greenhouse.  In this video, I grew a few strawberry plants using the Hydroton Clay Pebbles grow medium. I learned that Strawberries are quite temperamental and prone to root rot so if you build an ebb and flow grow tower like this, it is best to keep your watering to a minimum. While I ran the timer twice a day in this Hydroton Clay Pebble setup, once a day is plenty of watering and you might be able to cut back to only a couple times a week.
