Since your seed has already sprouted and been in placed into the right growing position, it’ll often pop its head out within just 12-24 hours! Sometimes you see just the leaves, but occasionally you actually see the seedling push the shell above ground. I keep the grow light on even before the seedling appears. It helps keep it warm and guide it toward the light.
The other reason I recommend to keep it warmer is because the plants just grow faster around 75°F in hydro. If your roots go from 60°F to 75°F, you’ll see the plants start growing faster in just a day or two, just like how plants in soil grow faster when it’s warm!
There are a few different ways to get cannabis seeds, with the most common being ordering seeds online and growing seeds you find in weed that you buy. Learn how to research and find the right strain.
Most seedling plugs will go back into place easily, and you’ll barely be able to tell it’s been opened

Hydroponics is an ideal method for germinating seeds! An alternative way of growing plants will be to grow plants hydroponically. Hydroponics is a more hygienic and efficient method compared to soil based growing. It also protects your plants from root rot or insects. You can also control the whole system as everything is automated in this growing method.
Seeds are also more cost-effective than buying one or two seedlings in the long run, as you can save some for the following year. The germination rate can decrease over time, but often, you can still get quite a few to sprout over the years until you have to buy your next seed packet.
Adding seeds to your hydroponic system means that they won’t go through any trauma or root damage from being transplanted into your system. This process may also introduce diseases or bugs into your hydroponic system from the store.
What You Need to Start Seeds in a Hydroponic System
Some people prefer to use a Ziploc bag, rather than a grow tray, when trying to get the seeds to germinate as it functions like a greenhouse. Seal the bag with a little bit of air and put it in a dark place for about four days to get the seeds sprouted. Then, you can put the starter cubes with sprouted seeds into the grow tray.
Inside of your grow tray, it can be beneficial to use a pot that works for your seeds and their future as seedlings in your hydroponic set-up. You’ll want to use starter cubes, such as those made of stonewool (rockwool). The key here is to use something that can withstand being immersed in water without dissolving, as it could clog up your system after transplanting.
Step by Step Instructions for Sprouting Seeds in a Hydroponic System
Give the root system a chance to naturally seek out the water and nutrients in your system by top watering it for a few days to give it a chance to grow the root system.
