Starting DWC Plants

No Dirt Plant Propagation


Starting DWC plants is a rewarding and relatively easy process.  When you start your own plant genetics for deep water culture (DWC) gardening, you can select genetics that are special to you–there are so many amazing types of plants that can be grown in DWC it’s tough deciding where to begin!  Additionally, when starting new plants from seed for direct transplant into the HydroBucket for growing to maturity, the plants will start off free of troubles–no insects or diseases.

TIP: growing in DWC makes it easier to maintain a hygienic growing environment as there is no soil for pests and pathogens to set up shop in.


The HydroBucket design makes transplanting a tidy affair: the HydroPod snaps securely into the HydroLid on top of the HydroBucket.  With a neoprene collar this supports plants big or small in the system without the need for grow rocks, etc to anchor plants in place.  When starting DWC plants from seed, a HydroPlug is ideal.  Also note that cuttings may be rooted in HydroPlugs for transplant into the system–but for today, let’s keep the focus on seeds.


What is a HydroPlug?


In essence it’s a relatively inert “sponge-like”’ material that holds the right balance of air to moisture, i.e. enough moisture for seeds to germinate while not becoming waterlogged, which could invite problems like damping-off. The plug itself is relatively small and fits perfectly with the HydroPod plant support. Of further benefit is that it is compostable once you’ve harvested your crop and are cleaning up to get ready for your next crop.


Starting DWC Plants


HydroBucket’s co-founder and inhouse water culture growing guru Mitchell has developed an easy and sure-fire method for starting DWC plants via seeding into HydroPlugs. Aside from the HydroPod used in the HydroBucket system and HydroPlug the only extra material needed is an opaque plastic cup that’s roughly the same size at the top as the HyroPod with a little extra room below.  To see how it’s done first hand, you can see Mitchell’s video HERE.


In a healthy propagation environment, the HydroPlug should stay moist for seed germination and early plant development for a few days in between waterings, although this can vary from setup to setup. 



The goal here is to have a healthy shoot emerging up top and root tips emerging below, after poking through the HydroPod.  The trick is supporting the HydroPod with HydroPlug slightly above a depth of fresh pH adjusted water or mild nutrient solution; far superior to sitting flat on trays.  To accommodate this, the right sized plastic cup can do a perfect job–see the VIDEO

Keeping the HydroPlug moist is easy–just hand water into the HydroPod with plug as necessary.  Any excess will collect in the cup, which you can pour into your favorite potted houseplant, etc.  By keeping an eye on the water level in the cup, it’s easy to maintain the perfect depth to coax root development.


Once seedlings have sufficient roots below and are tall enough to expose shoots above the neoprene collar once inserted, the deep water culture seedling is ready for planting into the HydroBucket and begin receiving crop fertilizer like Cultured Solutions.


Additional DWC Plant Propagation Tips:


Add UC Roots as recommended to help keep water and HydroPlugs free of funk in warm and moist environments


Use a humidifier and control to help keep Relative Humidity 70 to 80% for propagation and while establishing young plants


Raise lighting systems high up or use a dimmer if available); too much light too soon can fry tender young seedlings


Avoid direct air movement over germination medium or with tender young seedlings; it may dry out or stress them


Start with the best seeds available to you; in the case of heirloom veggies and fruits you may keep seed from the previous crop and plant again
