It depends on where you are. But generally it takes between 5-7 business days for your order to arrive.

Under optimal conditions, the cups can last ranging from 2-3 weeks on average. However, this duration can vary depending on the plant type and its growth rate.

Avoid direct sunlight and keep cups approximately 30cm away from an artificial light sources.

Keep the lid closed until you are ready to use the plant. Once ready, remove the plant from the cup and wash off the liquid or gel medium from the plant. Use lukewarm water and do not apply too much force, so as not to damage the plant.

Yes they are. They are produced in a lab under sterile conditions.

Yes you can. For our tissue culture plants, you can wash off the medium with tap water in your sink. The cup, the lid and the label can be recycled according to your local rules for recycling plastic.

Our plants are classified as Easy, Medium and Advanced. The later require more light to thrive. For this reason we can recommend following rule of thumb: <20 lumen or <0.5w/liter is ok for Easy category plants. Medium category plants require 20+ lumen or >0.5w/liter to achieve nice colors and healthy growth. Most Advanced plants have an inceased requirement of light and for this values up to 40 and more lumen or approximately 1w/liter is required.

You can calculate the
minimum required total amount of substrate by using the following formula: (LxWx5)/1000 = x liter of substrate for a total height of 5cm. For more complex calculations including slope in the back, use our substrate calculator.

Use easy plants with a mix of 80% fast growing plants and 20% slow growing plants  ie. Anubias or Cryptocoryne species. 

There is a myriad of different algae species on our planet. We classify algae in some main categories, to do so check out our Algae Guide.

When aquarium plants are moved from the nursery to your aquarium they go through an adjustment period. Many aquatic plants are grown above water at the nursery. This method produces stronger plants and helps prevent algae during cultivation. However, the leaves grown above water are not suited for life underwater.

Once placed in your aquarium the plant will begin to adapt to its new environment. During this process the old leaves may melt away while the plant develops new underwater leaves that are better suited to your tank conditions.

In most cases the best thing you can do is be patient. Leave the plant in place, remove the melted leaves, and allow the roots to establish. With stable conditions and proper care, healthy new growth will usually appear within a few weeks.
If the roots remain firm and new shoots begin to grow, your plant is doing exactly what it should.

Aquarium plants can turn brown for several reasons, most commonly due to nutrient deficiencies, lighting issues, or algae. In some cases the brown colour is actually brown algae settling on the leaves, which is common in newer aquariums and usually disappears as the tank matures.

It can also be natural for older leaves to turn brown and die as the plant produces new growth. Removing the damaged leaves will help the plant focus on healthy new ones.
