So you’re ready to get started in hydroponics and you’re about to start some seeds…
But you have no idea where to get started?
You’re not alone — when I first started gardening, I was a soil gardener.
One of the main benefits of hydroponics is the absolute control you have over your growing environment. Knowing that, I didn’t want to germinate seeds in soil and then transplant into a my hydroponic system, adding a bunch of dirt to the system.
There had to be another way.
Here are just a few reasons why you want to start seeds in a hydroponic system as opposed to soil:
- Much cleaner than starting seeds in soil
- Seedlings grow faster after germination
- Easy to transplant into a larger hydroponic system
That second reason is a cool one. As soon as your tap root pops out, a hydroponic system is going to help it grow faster than soil and prevent it from becoming rootbound.
Step 1: Get Your Materials
You don’t need much to get started. If you build your cloner yourself, the rest of the materials will cost you under $50 bucks and will last you for quite a while. If you decide to go with a store-bought cloner, it’ll bump up the cost a bit but you’ll also be getting a much higher quality product.
Seed Starting Materials List
- Hydroponic Cloner – You can either build your own or use something like the Clone King and starter plugs (#3 below)
- 2″ Net Pots
- Rapid Rooter Starter Plugs
- Seeds – find at your local nursery if possible, or buy many places online. A personal favorite of mine is RareSeeds.com
- Air Pump
- Air Stone
Step 2: Fill The Cloner With Water
Fairly simple step here. All you need to do is fill up your reservoir to just under where your net pots sit. Don’t worry about pHing your water or using reverse osmosis right now – standard tap water will be fine.
Step 3: Set Up the Air Pump
Place the air stone in the reservoir and connect the tubing. Connect the other side to the air pump and plug it in. You should see some beautiful bubbles start to come out of the air stone. These bubbles are what will keep the roots of your seeds moist and stimulate growth.
Step 4: Place Starter Plugs and Seeds
Soak each starter plug in some water and then place it in a net pot. The moisture will help the seeds germinate.
Drop 2-3 seeds in each starter plug. We use more than 1 seed because not all seeds will germinate and we want to make sure that every starter plug has a sprouted seed – otherwise we’ll have to replant!
Step 5: Maintenance
This system is very easy to maintain as your seeds sprout.
If you want, you can place a transparent cover over the top to keep in some moisture and increase the temperature of the system, but it’s not necessary.
Make sure to moisten the starter plugs with a few sprays from a spray bottle every day so your seeds have enough moisture to sprout.
When your seeds sprout, clip off all but the strongest seedling from each starter plug.
That’s it! Your seeds should sprout in 3-5 days for most plants and you’ll be ready to start growing some truly epic plants in your hydroponic system in no time!
If you’re more of a visual learner, I have a three part video series from my YouTube channel
Part One: The Basic Setup
This is the visual version of the blog post. Helpful if you just need to SEE to learn (like me).
Part Two: Making Sure Seeds Germinate
This part of the series talks about some of the maintenance and troubleshooting you might run into when starting seeds, including the infamous “why do they keep falling over” problem that a lot of beginners run into.
Part Three: pH Water and Add Nutrients
This part of the series talks about the need to pH and add nutrients to your reservoir after the seeds have germinated. Because they feed off of their seed leaves at the start of their life, you can get away with not doing this until the seeds germinate.
By the way, I’m using the Bluelab pH Pen
