Germination, Watering and Fertilizer

1. What is the ideal temperature?

The ideal temperature is 65-76°F/ 16-24°C.

2. When to adjust the light panel of height adjustable edition indoor garden?

Make the light panel at the lowest place of the light post when you start to germinate the seeds. And when the seedlings start growing and get taller, then keep the light panel 1"-2" above the plants to make sure they get the right amount of light.

3. When to remove the domes of the hydroponic indoor garden?

Remove the transparent domes when the seedlings nearly touch the domes.

4. How many seeds shall I plant per pod in the hydroponic indoor garden?

The quantity of seeds depends on the size of the seeds and the germination rate of the seeds. If the seeds are big and high germination rate, then you can put only 1 or 2. If it's small and kinda low germination rate, then you should put 3-5 seeds. Please don’t forget to check the seed packet for information regarding temperature and days to germination. Make sure the packed date of the seeds is as new as it can be. If the seeds are old, they may not be able to be activated. After you get the seeds and use a few of them. It's better to keep seeds dry and cool. A temperature between 32° and 41°F is ideal, so your refrigerator can be a good place to store seeds.

5. Does your hydroponic indoor garden come with seeds?
No, our product doesn't come with seeds. So you will need to purchase seeds from online or offline. Below are some information about where to buy.
1. Homedepot. (Ferry morse, Burpee etc.)
2., this company starts selling seeds since 1881, you may also see this brand's seeds in homedepot.
3. Some buy together products with our product on Amazon, or some are with high ratings with lots of reviews which may be helpful for you to choose reliable seeds.
6. How long will the nutrients in the smart soils last?

The smart soils themselves are already integrated with nutrients, the nutrients inside will last 2-3 months, so before no more extra plant food required. But if  you want to continue using the smart soils, you can purchase liquid fertilizer to add it into the water.

7. How much water shall I add into the tank when I plant from seeds?

When you plant from seeds, then add water level till the Min. water level, you don’t need to add water within the first 10 days as seeds don’t need much water at the beginning. When plants have more leaves and they will need more water, then add water below Min. water level but do not add too much water into the tank which exceeds the Max. water level mark on the indicator or higher than the Min. water level, both will hurt the plants’ growth. Keep water level between the Min. and Max. Mark (blue area) is always a good choice.

8. What are these space lids in hydroponic indoor garden for?

The spacer lids are used to cover the holes you don’t want to grow anything or expand the distance between pods. These covers are also for inhibiting algae growth.

9. Shall I dump the water in the hydroponic indoor garden periodically?

No, we don't recommend you the dump the water periodically as the nutrients will be lost due to this.

10. What's the frequency of adding water into the hydroponic indoor garden?
How frequently you are gonna add water depends on the environmental temperature, humidity, and the plants' status (if the seedlings are strong ang big). Please kindly check below cases.
CASE A (Plants-Grow fast)
Environmental Temperature: 65℉- 75℉
Environmental Humidity: 50%-60%
Plants:Basil, Lettuce, Micro Tom Tomato etc.
Plants Feature: Grow fast, leaves are big
Watering Note:   1.  0-12 days : Only add water once. Add the water to the level at Min. mark when grow from seeds as seeds don't require much water at the beginning. 
                           2.  12-25 days. Add water to Max. mark once per week usually. However, when the plants' leaves are very big like lettuce, then once per 3-7 days. 
                           3.  25 days+: At this stage, usually the plants should be big, they need lots of water, so the frequency is once 3-7 days.
CASE B (Plants-Grow slow)
Environmental Temperature: 65℉- 75℉
Environmental Humidity: 50%-60%
Plants:Thyme, Oregano, Rosemary, Parsley, Dill, Mint etc.
Plants Feature: Grow slow at early stage , leaves are usually small
Watering Note:   1.  0-12 days : Only add water once. Add the water to the level at Min. mark when grow from seeds as seeds don't require much water at the beginning. 
                           2.  12-25 days. Add water to Min. mark once per week usually. However, plants like Thyme, Oregano, Rosemary, their leaves are very small, so they don't need a lot of water as they are unable  to absorb all and fast, too much water will kill the plants.
                           3.  25 days+: At this stage, usually the plants are kinda big, then you can add water to Max. mark, they need more water then ever before, so the frequency can be once per week.
All in all, to grow plant well, we will need to make sure they are grown under the suitable temperature and humidity. More water will be required when leaves are getting more and bigger. Do not add too much water into the tank which will lower than the Max. water level mark on the indicator or higher than the Min. water level mark ( blue area will be safe area when plants have 3-4 leaves) , or both will hurt the plants' growth. 

Plant Care, Pruning and Plant Maintenance 

1. How do I prune herbs like basil?

Pruning your herbs is important to keep them growing and healthy in your indoor garden. You can start pruning when the plants are about 2 inches tall. Follow the main stem back to the previous leaf set and cut right above the 5th set of leaves. Cut the herb back about 1/4 inch above a node (the place where leaves come out). Leave a few inches of leaves (3 pairs recommended) on the plant after pruning. Never take more than 1/3 of the plant when pruning. Pinching or cutting back basil plants regularly encourages full, bushy plants. Trim a basil plant every two to three weeks and pinch off the flower buds as soon as you see them.

2. Can I transplant the plants in GrowLED hydroponic indoor garden?

Yes, you can transplant the plants. When you transplant, please take good care of the roots to take them out of the baskets and put the plants into the pots you have. And you can purchase the soils with nutrients like pre-mixed houseplant potting soil mixtures that can be store-bought or you can mix your own.

3. Why do my plants look unhealthy?

There may be a variety of reasons to look unhealthy. Usually it may be caused by over-watering, for this case, please reduce water to keep the water level above the Min. water level mark or take the plants out to dry for a couple of days. Also if the plants don't get enough light, it will become leggy, for this case, please make sure your light is 1"-2" above the plants. If you can't figure out why your plants look unhealthy, please feel free to submit the Contact Us form, we will help you to solve this issue like we always stand behind our products.

4. Can I grow different types of plants at the same time?
Yes, as long as the plans you are gonna grow have similar height and growth cycle. If you are a beginner, we highly recommend you to start with herbs like basil, mint, rosemary, as they have similar height and growth cycle. Lettuce is also recommended but need to take care of the leaves in case the large leaves cover other small plants which will not be good for other plants' growth (they may not get enough light). It's better to grow plants with smiliar height and growth cycle, or you will have a problem like how to place the light panel which will be good to all of them when they are in different heights.
5. How do I get rid of algae and mold on my hydroponic indoor garden?

It may happen that there are white mold and green algae growing along with your plants. Algae occurs naturally and sometimes can grow in hydroponic gardens or even in soils. Algae and mold are harmless to your plants so there is no need to worry. You may notice algae growing on the surface of the smart soils in your GrowLED indoor garden. If it bothers you, simply scrape them off if they are too aggressive, and sprinkle some cinnamon powder on the surface to absorb extra water as too much water will make algae and mold appear easily.

6. How to clean my hydroponic indoor garden before starting a new garden?

1) Remove any debris or dirt by rinsing the tank under water.
2) Soak the tank in three parts water and one part vinegar for 5 minutes. (This is a step to remove 

     PYTHIUM )
3) Carefully use a rag to scrub the tank to clean away any stubborn dirt or deposits and rinse under 

     cold water.
4) Allow the tank to air dry.
