How to Use a Super Sprouter

Tired of trying to remember all the components you need to get your propagation station up and running? Whether you’re an experienced gardener or just starting out, the Super Sprouter Premium Heated Propagation Kit is a great option to help your starts grow up happy and healthy. Each kit comes with most of the basic components needed for one full propagation tray setup.

Items you will need

  • Super Sprouter Premium Heated Propagation Kit
  • Seed-spreader tray (72-cell fits nicely)
  • Gowing media (root cubes, rockwool, coco plugs, or soil)
  • Spray bottle (optional, but a good idea)
  • Automatic, programmable lighting timer (optional, but a good idea)
  • Seeds or cuttings (for advice on taking cuttings, please refer to our Basic Guide to Cloning)

Start by selecting a seed-spreader tray and filling it with your preferred growing media. Place the seed-spreader tray into the bottom tray of your Super Sprouter.

The next step is to place a seed or clone into each hole. Every Super Sprouter kit comes with a small packet of Clonex rooting solution and booklet of advice from experts on how to get started if you need a helping hand. Locate these, and proceed! For seeds, the general rule of thumb is to plant twice as deep as they are wide. Once a seed is in, recover the surface quickly and gently, as seeds can be damaged by sunlight. For a clone, dip it into your rooting solution, make a sizable hole in your growing media, and set the clone in gingerly.

Carefully water your seeds or clones. A good way to do this without damaging the fragile root system or disturbing the surface of the substrate is with a spray bottle. Water is just fine, but some people prefer to use a seedling nutrient solution, liquid kelp, or other liquid seedling formula. If you want to feed right away, be sure to use the correct dilution ratio (water to concentrated nutrient) for seed/seedling application.

Now that your seeds/starts are thoroughly moist, put the kit’s humidity dome over the top, and place the entire setup onto the heating pad. Seeds and clones need warmth to grow! Each Super Sprouter heat pad is programmed to the correct temperature for creating an optimal seedling growth environment.

Last, place the included Super Sprouter strip-light on top, and attach a lighting timer, if you wish. Turn the light on, and sit back to watch for growth. If you started seeds, you should see sprouts emerge from the growing media within a week of planting. For both seeds and clones, make sure to keep the kit humid by applying water as necessary. Young seedlings do not have an established root system for uptake of water and nutrients, so foliar feeding is recommended to ensure that your plants will flourish.

Once leaves are showing above the growing media, the plant begins photosynthesis and needs light. The general rule of thumb for vegetative growth is 16-18 hours of light and 6-8 hours in darkness. Check online and see what your plant’s desired light-to-darkness schedule is; some variance is not uncommon.  The easiest way to keep your light schedule on point is by using an automatic timer.

In the next few weeks, keep an eye out for nutrient deficiencies or fungal issues. When roots are visible from the bottom of the tray, it is time to transplant.
