    For the more adventurous gardener, General Hydroponics offers the PowerGrower 8-Pack Kit!

    The PowerGrower 8-pack is 8 PowerGrower modules connected to one GH PowerGrower Controller. The controller is an integrated 17 gallon reservoir & a 17 gallon controller unit. The controller will maintain the nutrient levels in each module while the reservoir actively recirculates the nutrient to keep pH and PPM levels consistent. This ensures optimized plant growth & provides the grower with a lower maintenance garden.

    The newly engineered plumbing design ensures uniform delivery of nutrients to each individual chamber. The kit is powered by GH's Dual Diaphragm Air Pump & includes necessary hardware & Flora Series nutrients. The PowerGrower units can be arranged in a design to suit your growing situation.

    The PowerGrower 8-Pack Kit is built from high-impact plastic that will give you years of pleasure. Comes with everything you need to start your hydroponics garden.

      General Hydroponics PowerGrower 8-Pack Kit Questions & Answers

      What is a good inexpensive hydroponic system for the first time user?

      General Hydroponic's WaterFarm, PowerGrower and EcoGrower are all good systems for a beginner. Nearly any plant can be grown, and if you later decide you would like to have some additional units, they can be linked together and expanded with our controller.

      What is the best system for growing tomatoes, peppers and cucumbers?

      These plants have longer growing periods and need enough space for adequate root development. Our best systems for these crops are the WaterFarm, PowerGrower, EuroGrower and the EcoGrower.

      Can I turn my system off at night to conserve energy? Should I run it continuously or cycle it at intervals?

      All GH systems can be left off at night once the plant roots are long enough to reach the nutrient level in the reservoir. Longer cycles depend on the type of system you have:

      AeroFlo systems: The cycle can be set to run continuously during the day and coming on once or twice during the night on 15 to 30 minute intervals.

      EuroGrower systems: Set the timer to come on for .5 hour/ off 1.5 hour during the daylight cycle once the plant has a good root system. These systems use coco peat which holds moisture and nutrients in the root zone.

      WaterFarm, PowerGrower and EcoGrower systems: Set the timer to come on for 1 hour/ off 1 hour during the daylight cycle.

      RainForest systems: These units are run continuously, especially if you are trying to root cuttings. If you are growing plants, they can be shut off in the evening once the roots have grown into the nutrient solution.

      All GH systems can be run 24 hours a day 7 days a week for optimal results, power conservation is the only reason to cycle watering.

      What is the Controller, and what does it do?

      The Controller is a large external nutrient reservoir, which can supply make-up nutrient to as many as eight WaterFarm or PowerGrower modules. It provides an additional supply of nutrient solution as the plants move into their rapid growth phase. The larger Texas Controller can be used to supply up to 12 WaterFarm or PowerGrower modules, or it can be used in conjunction with the RainForest or EcoGrower systems.

      Can you recommend a simple solution for keeping growing media out of drains?

      The General Hydroponics' CocoTek Mats were designed for this purpose. The CocoTek mats can be cut to fit any application and come in two sizes, 4' x 8' x 1/4" or 4' x 4' x 1".

      Why is my WaterFarm or PowerGrower not dripping from the drip ring?

      Make sure the y connector for the 1/4" air line and 1/2" drip line (both are connected by the y connector and are the pumping column assembly) is on the bottom of the reservoir in the nutrient solution. There should be a 1/2" drip line to connect the drip ring tee to and a 1/4" air line to connect the 1/4" air line to coming out of the top of the pumping column support tube. If this part is correctly installed, check the drip ring, pumping column and y connector for debris and clogging. If the system still will not drip correctly give us a call at 888-815-9763 so we can help troubleshoot further.

      How do I deal with algae build up in my hydroponic system?

      The best method is prevention. If you keep the solution away from light, i.e. keep the lids closed and all openings sealed, you can prevent algae from growing.

      If you already have algae in the system you can remove it with a brush, or use hydrogen peroxide (3ml of 3% H2O2 per gallon of solution) to remove it. If there are particles floating in the nutrient solution, be sure to flush the reservoir and growing chamber with ample water, and then start with a new batch of nutrient. If the problem is severe, make sure you have the algae completely flushed out to avoid the risk of clogging some of the flow lines in the system.

      Are the plastic components used in General Hydroponics systems food grade safe?

      Yes, all of General Hydroponic's plastic parts are food grade safe. No chemicals will leach into growing plants. The plastics are also UV stable under artificial lighting and natural lighting.
