Plant sizes are shown as the grow pot diameter x the total height of the plant. This means the diameter of the grow pot at the top of rim x the total height of the plant including the grow pot. It therefore includes the plant roots etc as well as the height or length of the plant.
Please note: plant heights are approximate and are provided for indicative purposes only. Plants suitable for hanging may be depicted in a hanging grow pot, the actual grow pot used to ship the plant might not include these attachments.
For plants in soil the key size in determining the maturity and fullness of a plant is the diameter of the grow pot. The larger the diameter, the more mature the plant.
Hydroculture plants are measured the same way as soil plants, however the grow pots are sized by diameter plus their standardised heights, which allows a water meter to be fitted. For example: an 18/19 grow pot has an 18cm diameter at the rim and is 19cm tall.
Hydroculture plant roots have been specially adapted to grow in hydrogranules, which creates a smaller, more fleshy and hardier root system. This results in mature plants being available in smaller grow pots than their soil based equivalents.
Check the grow pot diameter:
Determine the plant's grow pot diameter. Compare this to the size of the opening of your chosen decorative pot and ensure it is big enough to insert the plant's grow pot through the opening (see diagram below).
We show the size of the decorative pot openings for each pot as you click the different size options or hover over the size buttons.
Tip: Pick a decorative pot that has an opening about 1cm larger than the size of the plant's grow pot. For smaller plants (up to 14cm grow pots) you should go slightly smaller and for larger plants (above 24cm) you can add 2-3cm without the pot looking too large for the plant.
Note: If the shape of the planter tapers strongly at the base, it might not be wide enough for your plant to sit squarely at the bottom. In this case you can add a liner on a small layer of pebbles to increase the size of the base. This will however raise the height of the plant slightly in the planter.
For hydroculture plants use the size tip to select a decorative pot that will accommodate the waterproof liner recommended for the plant in the hydro kit.
Artstone planters include a non-removable water reservoir, which raises the internal base height of the planter. These planters work best with the plant re-potted directly into them rather than left in their grow pots. If the intention is to leave the plant in its grow pot and sit it directly into the Artstone planter rather than re-potting the plant directly into the planter, please ensure you select a large enough size that will have enough internal height to hide the grow pot.
Check the grow pot height:
Soil plants - The height of the grow pot can vary slightly, but is usually slightly smaller or the same as its diameter. Check your planter will be tall enough to hide the grow pot if you are not re-potting directly into the planter.
Hydroculture plants - These require a hydro kit for assembly, this includes a waterproof pot liner with a base wide enough to accommodate the hydroculture grow pot. The size tip provided for each hydroculture plant provides a recommended size for the external diameter of the decorative pots that will accommodate the specified waterproof liner.
The grow pot height is standardised (normally 12cm or 19cm) and shown on the size option for each hydroculture plant. Ensure the external height of your decorative pot is at least 2-3cm higher than the grow pot height of the hydroculture plant.
Important: The opening measurement of the decorative pot is the size of the access hole for inserting the plant's grow pot as well as an indication of the minimum liner size needed. It is not the same as the external diameter of the pot which is the overall outer size of the pot. Please note all measurements are approximate and can vary slightly due to the handmade nature of our pots.
Note: Liners are "squashy" so they can be pushed through the opening to expand and fit closer to the pot wall once inside. Liners can also be cut down to size with scissors for a neater fit.
For round shaped decorative pots we provide the external diameter of the widest point so you get a sense of how large the pot is on the outside, as well as the width of the opening. We also provide the overall height so you understand how tall the pot is.
For square, rectangular and oval planters we provide the external dimensions for Length x Width x Height, plus the access width (internal width), as these are often displayed with a mix of plants.
Liners: Modern pots and planters come in all types of materials from ceramic, natural, composite, metal and fibreglass to create that wow factor in their setting. However not all are designed to be waterproof. To keep pots looking pristine and avoiding damage to floors and furnishings the solution is to include a flexible liner inside the pot.
Liners come in various sizes to fit the internal dimensions of the pot and can be trimmed down to size to create an unobtrusive barrier for the plant and soil to be potted into, whilst protecting the pot from unsightly calcium or fertiliser deposits from the soil.
In taller planters they allow for the soil to be contained to an appropriate depth for the plant, without needing to fill the entire vessel with soil. This ensures the root system is surrounded in optimum moisture content rather than it draining to the bottom beyond the roots.
Drainage: Traditional indoor plant pots have drainage holes and stand in saucers to allow excess water to drain freely. For modern decorative plant pots without drainage holes the grow pot could be stood inside the pot on a saucer, or in a pot liner for extra protection. Alternatively, for a professional design look, the plant can be repotted directly into a pot liner with a layer of hydrogranules to provide both a drainage layer and a reservoir for the plant. The roots above the granules will pull the water gently out of the granules (capillary action) to keep them moist but not wet.
Soil Depth: When repotting allow a little room for the roots to spread. The soil should not be so shallow that without drainage the roots will sit in water, nor so deep that the water drains below the roots leaving the plant to dry out.
Tall Planters: Fill the base of the planter with polystyrene foam or other packaging material that will not compress, up to the required height, then sit the plant liner on top with the repotted plant in the liner.
The hydroculture version of Sansevieria zeylanica is a tough, hardy snake plant. The long sword-like leaves are dark green with wavy lighter green bands. They have rather a rugged, shabby-chic appearance often with rough, brown edges. Some minor leaf cracking is also common.
Sansevieria zeylanica are not as common as Sansevieria trifasciata, but they are just as bullet-proof and just as stunning. Easy care, shade loving, hard to kill, air-purifying... these beautiful plants have it all.
Please note: some scaring may occur on the leaves.
Hydroculture Plant: Requires hydroculture assembly with hydrogranules, water meter, plant pot liner and plant food.
Light: Best in moderate to bright, indirect light but will adapt to low light conditions too.
Water: Water when the water meter has been on minimum for 2-3 days.
Temperature: Happy anywhere from 15-23°C and as low as 10°C for short periods.
Feed: Add a hydroculture liquid feed every 2 to 3 waterings during spring/summer.
Air Purifying: Sansevieria filter airborne toxins and are part of our clean air plant collection.
Height and Growth Rate: Ultimate height 75-100cm. Slow growing.
Toxicity: Mildly toxic if eaten. Keep away from children and animals.
Origin: Tropical West African Region.
Hydroculture plants are a form of hydroponic cultivation. Instead of using soil, plants are grown using mineral nutrient solutions dissolved in water.
Fruit and vegetables such as tomatoes and peppers are often commercially grown in a hydroponic system with the plant roots sitting directly in a nutrient rich water bath.
When it comes to indoor plants, the plant roots are supported in a grow pot filled with hydrogranules or expanded clay pebbles which hold the nutrient solution for the plant to absorb.
Hydrogranules are manufactured from clay pellets that are baked at high temperatures to make them expand, a process a bit like making popcorn. We only use the highest quality hydrogranules for horticulture made from purified and homogenised baked clay.
Traditionally hydrogranules have been used by interior designers for indoor plants in commercial settings such as offices, where easy-care greenery is essential. The open structure of the hydrogranules creates the optimum conditions for indoor plants to thrive as well as simplifying maintenance requirements.
In a word “Yes”. Hydroculture plants have a lot of benefits over soil plants:
Moisture Levels: The open structure of the hydrogranules creates optimum moisture levels around the roots of the plant. Water stored in hydrogranules below the roots will be gently drawn up through capillary action for the roots to absorb. No more dried out roots or root rot.
Watering: A water meter on the side of the grow pot indicates the amount of water left in the hydrogranule reservoir below the roots. When it reaches the minimum level simply top it back up to the optimum level. The plant will pull water from the hydrogranules according to its needs so there is no risk of over or under watering.
Root Health: The open structure of our pH neutral hydrogranules allows air to circulate around the roots keeping them healthy and because they do not compact over time there is no need to top up.
Hydroculture plants are adapted to these conditions and develop a smaller more fleshy root system making the plant more hardy and in a smaller growpot meaning you have a wider choice of planter styles. The requirement to repot as the plant grows is also significantly reduced.
Pest Control: Hydrogranules are an inert medium that is less susceptible to pests, fungi and bacteria which means healthier plants with less risk of disease.
Not all of our indoor plant range is available as a hydroculture version. Typically larger plants are available as hydroculture plants as our growers have to invest resources into adapting the plants from soil (where they start their lives) to hydroculture and therefore the focus is on the more popular varieties.
However, as people become aware of the benefits of hydroculture over soil the variety of hydroculture plants available continues to increase.
When you buy a hydroculture plant, you need a few other bits and pieces to assemble the plant in your chosen planter or plant pot. Think of getting a hydroculture plant as a solution that needs to be assembled rather than just a plant.
We have a simple step by step video guide below to assembling the hydroculture plant in a plant pot but essentially you need 5 things for hydro heaven:
The amount of hydrogranules you need for assembling the plant in a plant pot depends on the size of the decorative plant pot you are using for your hydroculture plant and how much you need to build up the base of the pot to sit the liner at the correct height for the plant to look good. (Assuming you are using hydrogranules as void fill below the pot liner).
Our hydrogranules are available in 10 litre bags and as a rough guide we recommend the following number of bags based on the external diameter of the plant pot you are using.
|External Diameter of Decorative Pot/Planter|
|28cm or less||29 - 34cm||35 - 38cm||39 - 40cm||41 - 44cm||44 - 48cm|
|1 Bag||2 Bags||3 Bags||4 Bags||5 Bags||6 Bags|
Note: Number of bags assumes void filling the base beneath the liner with hydrogranules.
Note: For taller style planters add an additional 1 - 2 Bags depending on size, for building up the base.
