Where is the reservoir?
The reservoir is built in.  No external reservoir is required. The entire lower forward portion of the system is the integral reservoir. Our design it truly modular; since each GrowTube has it's own reservoir section, the reservoir is automatically expanded  as additional GrowTubes are added, so each plant has the same volume of dedicated reservoir, no matter how large your system is.

How far will your completed systems disassemble?
The completed system will disassemble down to two levels. The first level .... for moving, cleaning, or harvest .... results in a reservoir assembly, along with a grow tube assembly for each run in the setup. The next level, for long term storage or transportation, results in the removal of the free standing leg and 90 elbow on each GrowTube. All levels of disassembly can be accomplished in five minutes without the use of tools. The guarantee of watertight operation is maintained after assembly/disassembly/reassembly .... without the use of any additional sealants.

How do you access the reservoir for measurements and nutrient additions?
The upstanding portion of the center GrowTube contains the fill port with lid. Easy access is made by simply lifting off the lightproof PVC cover. Ample room is provided for visual inspections, nutrient additions, and pH and TDS measurements. You can also take nutrient samples by opening the QuickConnect hose port and using the pump to deliver a sample into a container.

What are the three valves for on your system?
These valve handles control our convenient valve package. This feature results in a dramatic reduction in the labor associated with the maintenance of hydroponic systems, and is the subject of four separate patent claims. This built-in unit controls the powered pump overboard feature, reservoir self-agitation for mixing and self cleaning, and nutrient distribution features. Our clean running system requires virtually no routine cleaning. Our QuickConnect drain/fill hose attachment and powered pump overboard feature dramatically reduce the labor involved in routine reservoir changes, and eliminate annoying hydraulic-potential concerns. There is no more need to drain the reservoir tank to a lower elevation .... no need for a floor drain. You may now drain uphill.  You are able to locate your machine almost anywhere, and rely on the pump to empty your system, instead of gravity .... even uphill.  Reservoir nutrient change hassles are a thing of the past.

What areas are accessible for cleaning?
All interior surfaces are easily accessible .... this includes all portions of the reservoir and the entire length of each GrowTube. The system is completely light proof .... and runs perfectly clean. This helps eliminate insect infestations and algae, significantly improving cleanliness while simultaneously reducing cleaning labor. The system also contains a built-in self-cleaning capability that automatically removes particulate matter from the system. The filter element is commonly available, inexpensive,  reusable, is changed in less than five minutes, and only needs to be cleaned once every two years.

Please explain the function of your valves.
Our valve system inexpensively allows for a tremendous reduction in the repetitive labor common with routine reservoir maintenance and nutrient changes. All hydroponic systems require routine periodic nutrient changes in order to replenish the nutrients removed from solution by the plants. This labor can easily become an extreme burden .... depending  on the frequency of reservoir changes .... which jeopardizes the crop when neglected. Every 4-6 weeks is a common frequency. By automating the draining and refill, and auto-mixing during nutrient and pH additions, labor is reduced and system health is maintained. The valve system also eliminates any concern regarding hydraulic potential .... allowing the system to drain in most locations and orientations without the need for a floor drain. We solved these problems by designing into our system a cost effective system to empty the reservoir 'uphill', under pump power, regardless of your location. The pump overboard feature allows for much quicker reservoir changes. Once the tank is empty, simply reverse the flow in the attached drain hose by connecting the hose to the water source, and refill through the bi-directional port .... in one-fifth the time required when draining under gravity alone.

What watering schedule do you use with your reduced medium?
The system is extremely flexible with respect to the watering schedule. The roots are not deprived or able to dry out when the pump is not in operation because of the light-proof 99% humidity environment inside the GrowTubes. Some users run the pumps whenever the lights are on. We recommend starting the plants with something like 30 minutes of pump off every 3 hours when the lights are on. The optimum feed schedule will be dependent upon the grow methodology, type of plant being grown, and the users preference. The system is very flexible, which leaves the user's options open.  In addition, in our system the GrowTube environment is optimal for the uptake of oxygen throughout the root system .... thereby eliminating the need for secondary oxygenation sources such aquarium pumps, air stones, and bubblers. If desired, these auxiliary air units may be added easily, however our side by side tests demonstrate that they are not required.

What type of emitters do your systems use?
None! We have reliably designed the emitters, misters, and jets out of the system .... they are simply not required. Our patented pressure equalizing internal watering harness and distribution manifold eliminate the need for emitters by guaranteeing equal pressure at each plant site regardless of the number of plants .... thereby eliminating the major maintenance hassle of clogged emitters. We have our own custom designed turbulent-flow FeedStake now being produced for us which allows all feed lines to remain internal to our grow tubes. The FeedStake has a wide opening for steady flow, a turbulent port to oxygenate the nutrients prior to depositing at the base of the plant, and a threaded connection to eliminate the frustration of barbed connections. The threaded connection allows the stake to be easily twisted off for removal and reinstallation.   The pressure equalizing nature of our design allows for the use of a much smaller and less expensive pump than is required in other systems of comparable size ....benefiting the user with lower initial cost, ease of replacement, low noise levels, and extended life.

Where can I get a compatible pump for your system?
Our systems are designed to eliminate the requirement for a specialized pump .... even in larger systems. Your best source for an inexpensive  pump is North American Hydroponics.  We now supply pumps with all of our systems and, should you experience a failure, replacements may be ordered from us as well.  In an emergency, your local hardware store probably stocks the inexpensive and reliable Little Giant fountain pumps, which work perfectly in our system. The commonly available Dayton Hudson pumps, as well as the Maxi Jets, sold in most local grow shops,  also work well. Any standard submersible pump with a 1/2" diameter discharge port, and a flow rate of 900 or more liters/hr will function fine.

What is nutrient lockup and pH potential?
Without getting too technical: pH is a measure of the relative concentrations of the H+ and OH- ions in the root environment .... having said that, it may be best to think of pH as an electrical measurement. Simply put, if the electric charge is not correct .... the charged nutrient molecules are not accepted for use by the plant, i.e. they are 'locked up'. All plants have very specific pH requirements for the proper uptake of nutrients through their root systems. Most nutrients may only be utilized by the plant through a specific, narrow range of pH. An understanding of this simple requirement .... and an adequate nutrient supply .... is just about all that is required to remove the guesswork from growing. The proper pH control you can eliminate the constant guesswork involved in trying to diagnose nutrient deficiencies. It is just that simple! To control pH you require either constant attention to your system .... or a pH neutral design that maintains the pH you set ....effortlessly! This 'natural' pH level of the system is what is referred to as 'pH potential' .... it is the 'potential' or 'charge' on your system. This is the natural potential that you will constantly fight for the life of the system .... and it represents a major system cost .... in pH adjustment solutions, labor, and lost crop productivity. Our system .... by virtue of its pH neutrality and ease of maintenance .... eliminates these problems. The use of pH neutral, ultra-violet stabilized, food grade PVC components and a very small volume of grow medium results in the easiest, most productive, and most efficient grow system available.

How do you reduce the pH potential of your medium?
Our system is designed to support the root system in the optimal growth environment .... without the use of large volumes of grow medium. Eliminating the large pH potential of most mediums stabilizes the system. When combined with the neutral pH of our entire system, and the extraordinary cleanliness of our pump-powered filtering and light tight design, the result eliminates the single greatest cause of growing problems .... failure to maintain the pH within the range required for wide spectrum nutrient uptake. Our system's 3" diameter NetPots will support all popular mediums, including Hydroton, LavaRock, RockWool, or any other standard hydroponic grow materials.

Are your systems suitable for use outdoors?
Our systems are well suited for indoor, greenhouse, or outdoor use. With virtually no exposed grow media, all nutrient liquid is contained within the unit and is available for use by the plant. Cleanliness is maintained, and evaporation is reduced to losses due to plant transpiration only. The closed system is not open to contamination, and runs perfectly clean. System operation is the same, regardless of whether the unit is indoors or outdoors.

Why are your baskets so closely spaced?
Our systems feature an industry standard 6" (approx.) spacing, which has evolved as a standard due to the drive toward the most efficient production.  Many users believe that growing a large plant, by allowing it to branch during vegetative growth, will increase production.  Exactly the opposite is true for many crops.  Rather than allow the crop to use up valuable time in the vegetative phase developing branches, modern production methods put the crop into flowering mode and trim the plants extensively, forcing the plant's energy into the development of a few huge fruits.  These large fruits are harvested, and a new crop is started, resulting in a much higher yield over time since many for growth cycles per year are possible. This technique is commonly called Sea-of-Green.  Growers who prefer to allow their crop to branch may still do so by trimming the branches to fill the space between the GrowTubes, or by growing in alternate plant sites.  Sea-of-Green crop cycle times can be less than half the time required for traditional crops, by eliminating extensive vegetative periods.  Production is further enhanced by the compact plant size, resulting in the ability to harvest many more plants.

How long does the World's Greatest Growing Machine take to produce a crop?
Despite what other hydroponic manufacturers will tell you, no system will actually shorten the cycle time of your crop beyond the genetic limit of the crop.  However, any plant requirement (clean air, root-zone oxygen, nutrients, proper pH, and light) in short supply will extend the development time of the crop beyond the genetic limitation.  The World's Greatest Growing Machine supplies ALL plant requirements, eliminates excessive rooting as the plant searches for missing elements, and achieves the genetic limit of the growth cycle time...resulting in the fastest crop possible.
