What do you need to start seeds hydroponically?

Starting seeds hydroponically can be one of the easiest and most rewarding aspects of growing plants. Being able to grow seeds indoors and without soil is simple, but requires an understanding of what the seed requirements are - and these requirements change from seed to seed.

Fundamentally you just need a growth medium, water, light, adequate temperature, and patience.

1. Growth medium

For starting seeds, you want a growth medium that’s going to;

  • Hold the seeds above the water while still allowing them to remain damp.
  • Be soft enough for the seedling roots to be able to bed down, giving the plant structure.
  • Be stable enough to support the plant once it begins to sprout

Some good growth mediums include; coconut coir, a coconut husk mat or smart soil, but rockwool is the king of germination by far! 

For more info on grown mediums check out this blog post.

2. Water/moisture

Seeds need water to germinate, however, if you give them too much water then they may rot before they’ve had the chance to even begin sprouting! As a result, it is important that you keep your seeds moist but not drowned.

Misting/spraying freshly planted seeds is a good way to start seeds off, or if they’re in smart soil just wet it once and leave them to it! As you do this more and more you will be able to tell whether your seeds are wet enough just by look or touch.

3. Light

Seeds need light just like any plant! So, keep them well-lit but don’t scorch them! Dappled sunlight or an LED grow light are the way to go. If you’re using an LED light, we suggest a 12hr on/12hr off cycle to give the seeds the best chance of sprouting. For more info on grow lights check out this blog.

4. Temperature

Seeds like warm temperatures at around 23 degrees Celsius (however some tropical plants such as tomatoes or chilies may like it warmer).

To meet this it helps having a stable climate. Growing food indoors assists with this as indoor temperatures are generally more stable than those outdoors. Alternatively, you could use an incubator or greenhouse style germinating kit to guarantee the best results.

5. Patience

This is the most important aspect of any project! Seeds can take up to two weeks to germinate, and some seeds may never germinate! Its all a learning experience, as everyone’s soil, water, seeds, and sun exposure levels differ. As always, there is a little trial and error involved but don’t worry if one set of seeds doesn’t germinate, just try again!!

Sprouting jars are containers that provide the optimal conditions required for the germination and growth of sprout seeds.

Like most seeds, sprout seeds thrive in warm and humid conditions. Ideally, you would grow them at 25 degrees celsius and 60% relative humidity, but don't worry there is a lot of wiggle room with these two requirements!
