Frequently Asked Questions
Interested in growing with a Foody hydroponic system? Here are some of the most questions most frequently asked by people just getting started.
What about water? What pH should the water be?
The ideal pH range for most plants is 5.2 to 6.0 in hydroponic setups. Maintaining your water within this pH range will help ensure that the nutrients your plants need are available. Chlorine is one of those elements that is best if eliminated from your water source. This can easily be done by filling buckets or large bottles with water and just letting them stand for 48 hours prior to adding the water to your tower.
What is the proper total salt range for the water solution?
A salt range of 500 ppm to 1100 ppm is safe for most all hydroponic plants. The total salt level is an indicator of the level of nutrients in the water solution. Too high of a salt level will harm plants and too low will result in slow growth. As a general rule, plants will have a higher nutrient requirement during cooler months, and a lower requirement In the hottest months. Young, established seedlings or rooted cuttings are started at 500-600ppm. The TDS is increased to 800-900ppm during peak vegetative growth. During the transition from early to heavy flowering, TDS is further raised to 1000-1100ppm. It is then reduced to 400-500ppm during the final 2 weeks of flushing. A TDS meter is an essential tool needed when growing hydroponically.
What do I need to know about grow lights?
There are a number of plant grow lights and prices vary widely. The challenge with vertical towers is to get sufficient light to plants up and down the vertical spectrum. We've designed a vertical lighting tower which holds two T5 four foot long grow lights that works very well. It' available with a simple PVC support structure or with a very attractive anodized aluminum tubing.
How can I start my own seeds?
Seeds may be easily started using a variety of methods. We've placed small amounts of soil in used egg cartons and then planted seeds in them. Commercially available seeding trays are available that also work very well. Two that we recommend are Rapid Rooter and Root Riot cubes. The nice thing about the commercial cubes or plugs is that once the seedling roots grow through the bottom of the cube the whole thing may then be planted into a planting pocket of the Foody tower.
What is the Foody Tower made from?
Each Foody tower is made from food-safe plastic that is BPA free and UV stabilized for years of use.
How long does it take to set up a tower?
Set up of a Foody 8 Manual Watering tower, including putting soil in the growing pods, takes about 20 minutes. A Foody 8 Hydroponic tower takes a bit longer as it has more parts...usually 45 minutes. A Foody 12 Hydroponic tower also takes about 45 minutes. Step by step assembly instructions are provided and no previous gardening experience is required.
What's the proper water temperature for plant growth?
An ideal water temperature range is 65 to 75 degrees F. Cooler temperatures will not usually cause a problem but water that's above 80 degrees can be a detriment to healthy plant growth. The higher water temperatures promote root rot and diseases such as Fusarium and Pithium. Also oxygen levels of the water are lower at higher temperatures which is not good for the plants.
What kind of space do I need for a Foody?
Foody's may be placed indoors or outdoors. The tower itself only needs a 20" diameter of floor space. A total area diameter of 2.5 to 3 feet will allow plenty of room for future plant growth. Indoors it's best to place your Foody facing a southerly exposure near a large window or glass door so that it gets some natural light. All towers do need to be placed on a level surface. A set of indoor grow lights is recommended as they will greatly help encourage healthy plant growth.
