It’s like giving them a piece of your garden that fits in their hands—who wouldn’t appreciate a gift that grows?

When Used with Seedling Grow Tray:

30mm Microgreen Tray Mesh Bottom

30mm Microgreen Tray Mesh Bottom

The 30mm Microgreen Tray Mesh Bottom is 275mm wide and 535mm long. The mesh bottom makes this tray suitable for multiple uses.

With its low 30mm height, it can be filled to the brim using only about 4.5 liters of growing medium.

Coco coir based substrates/growing mediums are a very popular choice for growing microgreens at home, as it is a soft and airy medium with great moisture retention. Because the microgreen growing cycle is so short, with the seedling relying mostly on nutrients stored inside the seed itself, adding any supplements or additional nutrients to your substrate is not a necessity at all, although a lot of people do add a little bit of worm castings to their mixes, claiming better results.

Once you have added your substrate into the 30mm Microgreen Tray With Holes, water or mist spray lightly if the substrate is on the dry side and tamp the substrate down very lightly by hand, to get it to settle and flatten out nicely. Then gently sprinkle your seeds across the surface. Once this is done, a VERY thin layer of additional substrate may be sprinkled over the top of the seeds (using a baking sieve, for example)

Place the trays into a suitable environment for germination and mist or spray the top of the substrate regularly to prevent it from drying out. (A propagation dome will help keep substrate moist until your seeds have germinated, saving you a lot of effort. Remove the ). Do not overspray, as this will cause overly wet “swampy” subsurface conditions! Just keep the substrate slightly moist at all times.

Once your seeds have sprouted and grown to a harvestable size, you are able to clip off the delicious micro-leaves for your dishes and salads with a pair of pruning scissors.

30mm Microgreen Tray Mesh Bottom trays can also be used for other home and hobby purposes, like sifting out Mealworm Beetles if you are breeding them, or to sift grains, seeds, Perlite, etc.

Rooting plant cuttings is like performing magic tricks in the garden…

Valuable grow info from CANNA: HERE

You take a snip from a plant, wave your green thumb wand, and voilà! A new plant is born! Well, almost. It’s more like a science experiment meets a gardening adventure. You carefully select a healthy stem or leaf cutting, strip it of some excess baggage (aka extra leaves), and plop it into a cozy rooting medium—be it water or soil or a “glue plug”. Then, it’s all about providing the right conditions, like a plant spa day. You sprinkle a dash of sunlight, a splash of water, and a sprinkle of love. Before you know it, those little cuttings start sprouting roots like they’ve got places to grow! It’s like witnessing tiny miracles unfold right before your eyes. And hey, who knows, maybe one day you’ll have a whole garden of plants cloned from your green thumb genius. Just don’t forget to wear your magician’s hat while you’re at it!

RapidGrow Rooting Pots with Tray

RapidGrow Rooting Pots with Tray

RapidGrow Rooting Pots with Tray features 9 x 500 ml slotted pots that are narrow (+- 8cm diameter) and deep (13cm tall). This makes it ideal for quickly rooting seeds, seedlings or clones into a good sized root volume – ready to transplant into a larger container!

CAN BE BLACK OR GREY PLASTIC, depending on availably.

The slotted pots of the RapidGrow Rooting Pots with Tray are similar to net pots and air pruning pots – allowing for great drainage and aeration of the roots and substrate, factors that all play a role in root development.

The 9 pot tray makes it easy to handle, move, water and maintain multiple seedlings or clones at once. The tray with the 9 pots inside of it measures 30 cm x30 cm x 16 cm high.

If you are looking to generate healthy root mass quickly, we recommend using Cosmocel Cosmoroot Rooting Promoter as early feeding for clones and seedlings.

Cosmoroot promotes and strengthens root formation and root development. Cosmoroot is a Bio-stimulant and should be used in conjunction with a regular nutrient feeding plan.

To increase yields you need to increase root mass. The bigger the root mass the more nutrients can be absorbed by the plant. A good root system results in healthy vascular tissue formation, this means well developed fruit or flowers. Roots synthesize the hormones responsible for cell division and enlargement, so the more roots you have the bigger the yield.

  • Growing Microgreens

    Microgreens are simply greens, lettuces, and herbs that are harvested when they are quite young — generally when they are approximately 5 – 10cms tall.

    What Can You Grow as a Microgreen?
    Basically, you can grow any lettuce, salad green, or herb as a microgreen. It’s easy to start with a pre-packaged seed mix.  We have an Eden Seeds mix which contains Cabbage, Broccoli, Cress, Kale, Mizuna, Mustards Red and Green, Radish, Tatsoi.

    How To Grow Microgreens
    Microgreens are very easy to grow. You can grow them outside, in a garden bed or in containers, or inside on a sunny windowsill.

    If you are planting microgreens in a garden bed, loosen the soil and rake it smooth. Scatter your seed mix so that the seeds are about 5mm apart — remember, we’re harvesting them very young, so they don’t need a lot of room. Once the seed is scattered over the area, cover it with about 5mm of soil and water gently but thoroughly.

    If you’re planting in a container, the first step is to choose a container that is at least five centimeters deep and as large in diameter as you want. Fill it with a good quality organic potting mix, and smooth the soil. Scatter the seeds so that they are about 5mm apart, and cover with about 5mm of soil. Water gently but thoroughly, and place your container in a spot where it will get at least four hours of sunlight.

    In either case, do not let the soil dry out, and be sure to remove any weeds so that the tiny greens don’t have to compete with them for water and nutrients. Because you’ll be harvesting the greens so young, you don’t really need to fertilize them while they’re growing. If you’ve got plenty of organic matter in your garden bed, that will be perfect.  Microgreens grow for such a short period of time that they are rarely bothered by pests and diseases. However, if you are growing brassicas in your mix (mustard, kale, etc.) and cabbage worms are a problem, you may want to cover your microgreens with a net (a piece of old curtain mesh is ideal) cover to protect them.

    Harvesting Microgreens
    The best time to harvest microgreens is when they’ve developed their first set of true leaves (the first ones are seed leaves, and don’t look anything like the actual leaves of the plant), which is generally about ten days to two weeks after planting. To harvest, simply snip the microgreens just above soil level.

    Unlike mesclun or baby greens, you won’t be able to get additional harvests from one planting of microgreens. Because the plants haven’t had much time to develop, and you’re snipping off everything except the very bottom of the stem, the plant has no way to generate new growth. You can plant another crop after harvest by simply scattering fresh seed and covering it with soil. You don’t need to remove the old roots; they are good sources of organic matter.

    As you can see, microgreens are simple to grow, and provide you with a quick harvest for not much work. You can add them to salads, sandwiches, or stir-fries, and it’s much cheaper to grow your own than it is to purchase them. Experiment with different mixes, adding the varieties you like best. They’re definitely deserving of a spot in your garden.
