There are many reasons that cause seeds not germinating such as: insufficient moisture, lack of oxygen (e.g. seeds fully submerged in water), over exposure to sunlight, too high/low temperature, seed quality or pests. And each species has its own characteristic and therefore ideal germination conditions vary. Our checklist goes: moist growing media, air, warm temperature, and avoid sunlight in general. If you check on all these and are still unsure, feel free to contact us at cs@grow-green.com

Using a Seed Starter can help to improve germination. Seed starter is designed as an incubator to provide a stable environment and therefore enhance germination for different types of seed. In addition, it can help to shorten the overall planting time in the actual planting environment.

Definitely! Seeds are living things, but in a dormant state. They are better kept in a cool, dark and dry place when you are not planting them yet. Our recommendation: Store in a dry, cool place between 8°-15°C (45°-59°F), away from light.


  • You can start harvesting basil by picking leaves after your plants have at least 6 sets of leaves (about 6-8 inch tall). Pick leaves or pinch at a node. Each cutting will help the plant branch out more.
  • If your tomato plants are not ripening on the vine, you can try removing old leaves from the stem or adjusting watering. Too much watering during ripening will delay ripening of the fruits. In addition, temperatures also affect tomato growth: temperatures above 85F or below 50F will affect tomato growth and ripening.


  • In your garden, bugs typically coexist and live with plants without harming them. Some, even help pollination. On indoor plants, bugs are a common and a more serious problem. They can enter places in various ways; through a windows, on clothes and even on other plants.
  • To minimize the chances of infestation, keep checking your plants regularly and remove infested leaves if you see any.
  • If you have an aspara, keep your aspara clean. For cleaning advice please check cleaning tips on our website https://www.grow-green.com/clean-and-sanitise-your-device/. For any concerns, feel free to contact our customer service cs@grow-green.com for further assistance.
  • Fruit flies and more often flies similar to them, called fungus gnats, are very common, especially on indoor plants grown with soil. As they feed on decaying organic matter in dump soil.
  • To minimize the chance of infestation have a regular watering schedule that does not leave the soil too moist and remove dead plant parts regularly. Pruning plants regularly and reducing humidity also helps. If flies appear monitor and control their numbers by setting sticky yellow traps.
  • Hydroponics growing reduces the possibility of infestation as there is no soil.


  • If you are using a DIY hydroponic system, a way to avoid smell is to: use an air pump, change water weekly and use sterilized water.
  • Using mineral instead of organic fertilizer reduces the possibility of bacterial growth in the roots of your plants.
  • You can consider using a smart grower with automatic water circulation. Find yours at www.grow-green.com
  • Hydroponic plants completely depend on nutrition you provide them. If your hydroponic plants are wilting it is probably due to improper balance in nutrition or lack of certain minerals.
  • When using aspara, the smart sensor will detect a lack of nutrition and alert your through an app and the problem will not happen.
  • In theory hydroponic plants should grow faster than plants grown in soil. Plant growth is, however, also affected by the lights, oxygen availability in water and water pH as well as the temperature. If your plants are growing too slow, check these factors.


  • Plants can die for various reasons such as: overwatering, underwatering, improper nutrition, pests, insufficient light or poor soil quality.
  • Our checklist goes: regular watering and feeding schedule, light exposure and pest check. If you check on all these and are still unsure, feel free to contact us at cs@grow-green.com
  • Brown leaf tips on plants are most often a consequence of improper nutrition.
  • If the leaves are more than 50% damaged, cut them off. You can also cut the oldest leaves.
  • Plants’ leaves typically turn yellow when plants are overwatered or underwatered.
  • To improve this, maintain a regular watering schedule or make sure your hydroponics have a constant water level.
  • When planting in the aspara Smart Grower, the built-in smart sensor will notify you when your plants need water and you will receive notification through an app on your smartphone too.
  • Brown spots usually appear with improper watering.
  • To fix the underwatering and/or overwatering, set a regular watering schedule. Removing old, soft and discolored leaves can help as well.
  • Curling of the leaves is usually plants’ response to extreme drought or heat.
  • Make sure you water your plants and keep them in well aerated space. Once curled leaves, usually do not uncurl, but if conditions are improved the new leaves will not curl.
  • A variety of factors affects plant growth. For plants grown in soil, the availability of water is often the main factor.
  • Check if the soil you grow your plants in is moist enough. In addition, plants grown in soil often outgrow the pots they have been initially grown in. If the roots of your plant are growing at the surface or through the drainage hole, it is time for a bigger pot.
  • Herbs originating from different places around the world have different growth requirements. Mediterranean herbs such as oregano, rosemary and lavender require full sunlight whereas for mint, thyme, coriander or tarragon full sun and hot weather is not so favorable. Overwatering also often affects the way herbs grow.
  • Maintain a regular watering schedule and adjust nutrition. For herbs grown in aspara Smart Grower, it is so easy because aspara will alert you about your plants’ needs.
  • Flowering in lettuce also known as Bolting happens when the plants shift from leafy growth into flower production stage. This can be caused naturally, by aging or in the summer, while in indoor planting it is very often caused by a variety of factors such as high temperatures, too long daylight hours or too much artificial light, inadequate moisture, underwatering or drought.
  • To delay flowering make sure your lettuce is properly watered and not exposed to direct sunlight, especially if you live in an area with hot summers.
  • Long stems, or stem elongation are typical symptoms of insufficient lightning.
  • Try moving your plants to a place with better light exposure or adding artificial LED lights.
  • You can consider using a aspara smart grower where has specific plant programs and provides suitable lights for your plants.
  • Most of hydroponically grown plants need higher potassium in order to grow fruit. Adjust potassium levels during flowering stages.
  • If your plants are bearing fruits, but they are small and deformed, this could be a pollination issue. Indoor plants are often not exposed to pollinator insects such as bees so they may need your help with pollination. If you need help with pollination, check this out https://www.grow-green.com/pollinate-flowers/ or you can contact our customer service via cs@grow-green.com
  • Mold and fungus is very common on plants, both indoors and outdoors.
  • Fortunately it can easily be prevented or relieved by reducing and controlling humidity, providing proper lightning and aeration and tool disinfection.
  • Mold and fungus is more common in plants grown in soil due to the ability of fungal spores to survive dormant in soil. To prevent this, use good quality soils from sealed packages or try hydroponic growing.

  • Most bugs and flies are attracted to open water sources. aspara smart grower is a concealed hydroponic system with no water exposed. So, please don’t worry about insects!
  • If you are growing fruit or root plants (e.g. tomato, radish), we would suggest you to harvest on time. Rotten fruits on plant or grow tray may attract insects.
  • Please add nutrients according to the instructions.
  • We would recommend using our nutrients for the best plant growth.
  • If it is not your first time planting, try washing all your aspara removable parts (grow tray and tank all parts). We will recommend you to clean your aspara and replace all the water after your each planting to make sure your system is clean so that your plants of next planting will not be affected.
  • We would recommend pruning which promotes larger harvests.
  • Pinch off sprouts and branches start to grow off of the central stem, and (with) leaves that look dry or dead. These little sprouts and branches will rob the plant of nutrients. Pinching them off makes sure your growing cherry tomato plants will continue to flourish. You will need the pruning when the stems are around 15-20cm (6-8in) tall. Pinch off stems higher than 15-20cm (6-8in) to make sure the plant is not too tall. Plant too tall will burn and you may also burn your grower!
  • Increases the amount of nutrients can improve fruit productions.
