Sea of Green Hydroponics

Hydroponics continues to make its way into the mainstream, and with this popularity hydroponics specific retailers are finding their way into towns and cities across the country. Fortunately for those who are not lucky enough to have a hydroponics store nearby there are a wide variety of online resources for equipment, supplies and information, but for those with access to these new retail stores they offer community, support and advice as well as a variety of products to choose from.

This article presents an advice filled interview with Justin C. one of the owners of Sea of Green, a growing hydroponics retailer founded in 1992, with two stores in the Phoenix Arizona area and one in Tucson.

Question: What are some of the most commonly asked questions you get about hydroponics for the home gardener?

Answer: “How does hydroponics work” is probably the most common question. It seems like such a strange and misunderstood concept to many people. Hydroponics means growing plants without dirt, all the food for the plants is in the water instead. People think it is a really complicated process, but if you can measure out teaspoons you can probably figure out hydroponics. In Arizona there is also a buzz about wanting to know if you can do hydroponics outside. The answer is yes, however hydroponics is often about control to get optimum growth and so doing hydro outside just takes a little more consideration.

Question: What are the biggest advantages of hydroponics for the greenhouse gardener?

Answer: The biggest advantages are more plants in a much smaller space, ability for total environmental control, no need for toxic pesticides, and speed of growth.

Question: What are some of your favorite hydroponics systems at various price breaks (low, medium and high) and why do you like these systems?

Answer: Bucket systems are the lowest cost and often the most successful units for anyone interested in trying something like a single pepper plant or an assortment of herbs. This system generally consists of a five gallon bucket with a pot insert and a drip collar on top that recirculates water 24 hours a day. The system is easy to setup, requires limited maintenance and is relatively inexpensive. A middle range system would be something more automated like an ebb/flow type system on a timer. This system consists of a reservoir that usually sits underneath the tray supporting the plants. Water floods the tray several times a day, per the timer, and then drains back down to the reservoir. This system is more aggressive then a bucket system and give growers a little more flexibility to grow more then one plant. Aeroponics is the most expensive type system where the roots hang in the air with nothing around the roots except the spray of nutrient solution with a high power pump. This is the super charged system, but this system is the least forgiving. I would never recommend it for the novice, but rather for the experienced hydroponics gardener who wants to get twice the yields in about half the time.

Question: What are some of the biggest mistakes home gardeners make with hydroponics?

Answer: Hydroponics is a skill like anything else and sometimes it is necessary to tinker with a system to get it dialed in for the aggressive growth that is possible with hydroponics. Patience is very important and if anyone sticks with it even a few months they can be very successful. It is also a very experimental hobby and no one person has all the answers. Everyone has a situation that is a little different and everyone’s setup is different. Besides small errors like pH, or over nutrient levels, people often rely on simple answers from books that don’t account for a grower’s particular situation. Personal experience is the only way to get it right.

Question: Can you give us a few of your favorite tips for home hydroponics?

Answer: Start simple, but don't overlook all fundamental parts of plant growth including light, CO2, temperatures, etc. Keeping a grow diary helps to keep track what you did right or wrong. Check pH! Especially if using chemical nutrients over organic nutrients. Organic nutrients are easier to use, but chemical nutrients can give faster growth. And be patient!

Question: What do you see in the future of hydroponics for the home gardener?

Answer: It is taking off as a popular form of gardening with more people getting into it every year. The thing I love the most about this industry is that you are constantly learning new things and the innovations never cease. For the home gardener it is a relatively new concept, maybe 50 years old, or so. But the expansion of the industry is reducing the cost and simplifying the methods so that even novice gardeners will succeed with hydroponics. The growers who come to us at the store are not in one time and that’s it. We build a relationship with our customers and see them coming in every week, year after year, learning from us as we learn from them.

Hopefully the trend towards more local hydroponics retail outlets will continue and this may even push the traditional garden centers to include more resources for indoor, greenhouse and hydroponics gardening.
