Supercharged aeroponic cloner for larger cuttings!
The RainForest® 318 is dual use. Growers can propagate 90 cuttings into 3" rooted plants for transplantation into any system. The cuttings grow into the CocoTek® coir caps that are included. Or, use the 318 to accommodate up to 18 small plants from cuttings all the way to harvest. The system's Vortex® Sprayer oxygenates the nutrient solution then gently sprays it over cutting bases or root systems.
For propagating cuttings or for quick-starting seeds, seedlings, or transplants, no hydroponic system exists that will match the performance of the RainForest®. The Vortex® Sprayer lifts and oxygenates nutrient solution then gently distributes over cutting base or root system, giving you the most oxygen in the root zone possible.
Many growers choose to start their plants in RainForest® modules and later transplant them into larger systems like the GH WaterFarm®. Several RainForest® modules can be connected to a Texas Controller for larger installations.
This system includes:
- 17-Gallon Reservoir with Lid
- Six 3" Lid inserts
- Vortex Sprayer
- 3 inch Grow Cups
- CocoTek Liners and Caps
- 3-Part Flora Kit

General Hydroponics RainForest Modular 318 - Vortex Sprayer Questions & Answers
Do I need a humidome for my RainForest system?
No, a humidome is not necessary. The Vortex sprayer, included in the RainForest 66, 318 and 236, supplies an ultra fine mist of water, oxygen and nutrient in just the right amount for cuttings to survive until roots form. As with the Vortex sprayer, the pumping set up used in the RainForest 36 will also supply the right amount of water, oxygen and nutrient for cuttings to survive until roots form.
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.
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.
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.
Which is the best system for growing smaller plants?
You can use any General Hydroponic systems, though the AeroFlo produces the most rapid and dramatic results.
