Yes, you can absolutely start seeds in a hydroponic system. Instead of traditional soil, you will use a soilless growing medium to anchor the seeds. The most popular materials include rockwool cubes, Rapid Rooter plugs, or coconut coir.
In that case, you should be able to start your seeds in your hydroponics set-up. That's good, esp when you are a beginner. I used to start mine indoors, in a propagation tray and move them outside (mine was an outside set-up, in the tropics where the sun was much more harsh,) once they were bigger.
3 Types Of Plants To Avoid Growing In Your Hydroponic Farm
5 Disadvantages of Hydroponics
Tap water can be used but often contains chlorine, chloramine, and minerals that affect pH and plant health. Let tap water sit for 24 hours to off-gas chlorine, or use a dechlorinator. For best results, use filtered water or reverse osmosis (RO) water and add nutrients from a clean baseline.
It is not inherently illegal for you or a farmer to replant seeds, but it is illegal to replant patented seeds or those protected by commercial contracts. Seed companies use these legal mechanisms to protect their investments in agricultural research and development.
Since hydroponics do not use soil, many traditional organic growers feel that they are not eligible. If people want to see the organic certification sticker on their fruit or vegetable, they will not be able to do so at this time on produce that is grown hydroponically.
For most standard hydroponic systems, you should perform a full water change and clean the reservoir every 10 to 14 days. This schedule prevents nutrient imbalances, salt buildup, and harmful root diseases.
While growing plants in a hydroponic system helps reducing the risk of soil-borne diseases, the continuous circulation of water through the system puts the plants at risk of contracting some waterborne diseases. Sometimes, these diseases are carried by the water solution from one plant to the rest.
Research has shown that English Ivy can eliminate up to 78% of airborne mold within 12 hours. This makes it particularly useful in humid areas like bathrooms and basements where mold growth is more common.
“Poor Man's Fertilizer” is an expression to describe an early spring snow, and there's actual science behind it! “Snow and other forms of precipitation contain nutrients such as nitrogen and sulfur.

Seeds that should never be started indoors include root vegetables (like carrots, beets, and radishes), large vining plants (like squash and cucumbers), and fast-growing legumes (beans and peas). These plants are either easily damaged during transplanting, suffer from root shock, or grow too rapidly to be successfully moved.
Therefore, most seeds need just three elements to germinate: Water - Consistent moisture allows the seed to swell and start the chemical process beginning the growth. Oxygen - The seeds need oxygen so they can have the energy for growth. Temperature - Warm and cool temperatures speed up and slow down seed growth.
Although city water treated by municipalities must meet the minimum EPA standards, well water is not regulated and can also contain harmful contaminants like chromium, arsenic, or bacteria. While city or well water may meet drinking water standards, it may not be ideal for plants or hydroponics.
Cons
Increased oxygen helps in the growth of roots as well as improves the rate of nutrient absorption. Even the basic hydroponic systems employ some type of direct injection of air. This air can be pumped into the nutrient reservoir or directly to the root system of the plant.
The most profitable hydroponic crops are fast-growing leafy greens, specialty herbs, and high-yield fruiting vegetables. Farmers maximize margins by targeting quick harvest cycles, high-density vertical planting, and consistent restaurant or premium market demand.
Mistake: Assuming plants will grow well without proper temperature or humidity management. Plants grown in hydroponics are sensitive to heat, light, and humidity. In hot and humid areas, failure to manage temperature can lead to plant stress, algae growth, and fungal infections.
NASA uses hydroponic systems aboard the International Space Station (ISS) to grow crops like lettuce, radishes, and wheat.
An example of a very old viable seed that was excavated from the Arctic Tundra and germinated and flowered after an estimated record of 10,000 years is Lupinus arcticus. It is a type of lupine and is an example of a very old viable seed.
The Agricultural Adjustment Administration (AAA) paid farmers not to grow crops to reduce severe agricultural overproduction and artificially inflate crop prices. This was done to stabilize the rural economy during the Great Depression by raising farmers' purchasing power.
