About this item

  • [BENEFITS OF USING ROCKWOOL]- Rockwool cubes are superior to other typical hydroponic substrates, with up to 96% porosity and 91% water-holding capacity allowing for free flow of nutrients, water and air, encouraging roots to grow deeper and wider. What’s more, rock wool increases growth rate and yield with a shorter planting period
  • [MULTIPLE GARDENING USES]- Growers like to use grow cubes for horticulture and primarily in hydroponic production, it is ideal for starting seeds, clone plants, growing vegetative and fruiting crops. Hydroponic growing medium is also suitable for different growth cycles of plants, both short and long-term, steer them towards flowering or fruiting growth
  • [SIMPLE USAGE GUIDE]- You need to soak hydroponic seed starter (its naturally alkaline) in acidic water until the pH value is stable between 5.5-6.5 for 24 hours, and take it out for use. Then put the stonewool cubes into a tray or container and insert the seeds, now you can wait for them to take root and transplant them to other growing media when necessary
  • [EASY TO TRANSPLANT]- Seed starter plugs and all can be transplanted into their new home, which is less disruptive for the plant and allows for quicker acclimatization. Short transition period for transplanting and root colonization, the independent root system bring higher survival rate. No matter the transplanting or the cloning, we all promise the quick and high survival rate
  • [ENVIRONMENTAL CONTROL]- Hydroponic rockwool cubes have much more control over what goes into their plants’ root zones, it can control nutrient and moisture levels more easily than with other media, reduce the temperature difference between day and night, keeping the temperature of root. In addition, rock wool cubes can promote root breathing and avoid continuous cropping obstacles



Product Description

Rock Wool Planting Cubes 1 inch

Rock Wool Squares

Rock wool cloning cubes is a versatile growing medium that is playing a growing role in farming, giving you more benefits than other options.

Let's see what advantages it has!

  • Hydroponic rockwool can be used for direct seeding, propagation by cuttings or transplanting. It is lightweight, so it is easy to handle, store and transplant.
  • With up to 96% porosity and 91% water-holding ability, rock wool for plants creates a structure perfectly suited to retain water while holding more oxygen than typical mediums.
  • Planting cost reduction:The unique planting substrate lowers down the frequency of irrigation of water or fertilizer, thereby reducing irrigation costs and facilitating later maintenance.
  • Compared with other soilless media options for hydroponics, the rockwool seed starter speeds up crop growth and achieve more yield in a shorter planting period.
Hydroponics Growing Supplies

Made of the molten basaltic rock, the starter plugs are produced at a high temperature of 1500℃, creating a healthy growing environment for plants.

You know what you are getting once you have used them.

  • Good thermal insulation allows plants to maintain a suitable temperature
  • Control root moisture and nutrition Levels
  • Discourages overwatering and root hypoxia
  • The plant root system develops independently
Cloning Pods

Rockwool grow cubes will bring higher germination rate and yield to your crop.

  • Numerous studies have found that rockwool blocks have a 20% higher germination rate than other soilless media.
  • In addition,total yields and weight are also higher in rockwool starter plugs than some other media.
Rockwool Starter Plugs

Rockwool starter cubes are safe for hydroponic use and have many advantages for hydroponic production.

  • In hydroponic production, they can be used for starting seeds, growing vegetative and fruiting crops.
  • Once the moisture reaches the ideal saturation, the grow media remains in place. This stability is important for any system with flowing water.

I ordered these and though they were fine. I ordered the wrong size, so with it being so small. It was hard to get the seeds in without it. Breaking, make sure you measure the size you need before ordering!!

These little rockwool cubes work perfectly for growing lettuce or other greens in a hydroponic setup. My "deep water culture" indoor setup uses two bussing tubs with nine 1 1/4" holes drilled into the cover of each tub. 18 small net pots are inserted into the holes and then the rockwool cubes with already-started lettuce seedlings are placed into the net pots. Add water and nutrients, plus an airstone in each tub pumping in oxygen for the roots, and you have a nice little garden producing fresh lettuce all year-round.

This is much better than those stinky little sponges, I find it easier to work with and it stays wet for a longer period of time. If I have too many plants for my hydro unit these transfer easily to my raised garden. You get quite a few and they store well.

I recently tried using the SKINNYBUNNY Rockwool Cubes for my hydroponic planting needs, and it turned out to be a cultivation catastrophe that left my gardening efforts in ruins. These cubes, which were supposed to facilitate soilless culture and transplanting, fell far short of my expectations. 🌱🙅‍♂️The advertised convenience of these cubes was non-existent. It's like trying to assemble furniture without the instructions. The supposed ease of use was overshadowed by the lack of guidance on how to properly prepare and use them. This resulted in confusion and frustration, making the transplanting process anything but straightforward. It's more of a horticultural headache than a practical solution. 📦🌿The quality of the Rockwool Cubes was questionable. It's like building a house with crumbling bricks. The cubes began disintegrating and shedding fibers, which I believe are not ideal for plant health or the environment. Their fragility made them a poor choice for a gardening medium. It's more of a gardening faux pas than a reliable tool. 🏗️🪴The promised hole design was more of a hindrance than a help. It's like trying to fit a square peg into a round hole. The holes often seemed too small or irregularly shaped, making it difficult to insert seedlings or seeds. This design flaw added an unnecessary level of complexity to the transplanting process. It's more of a holey ordeal than a convenient feature. 🔲🕳️In conclusion, the SKINNYBUNNY Rockwool Cubes turned out to be a significant letdown for my hydroponic gardening efforts. Their lack of clear instructions, questionable quality, and inconvenient hole design make them an impractical choice for soilless culture and transplanting. If you're serious about your hydroponic or soilless gardening, I strongly recommend exploring other options. These Rockwool Cubes are more likely to leave your gardening aspirations in disarray and disappointment. 🌾🚫🌿
