Although there may be more oxygen dissolved in the water at lower temperatures, at least in my grow tent that apparently isn’t the limiting factor to growth, because plant growth speeds up at warmer temperatures.
Just like in soil, cannabis plants in hydro tend to grow faster in relatively warm temperatures. This is a somewhat controversial statement because a lot of hydro growers prefer to keep their temperature lower in the grow space to help prevent root rot. In fact, there are some growers right now who are reading this and shaking their heads at me.
I do agree that if the temperature is above 80°F, your plant is a lot more likely to get root rot. However, I personally have not found that cool temperatures are adequate to prevent root rot. Even if the temperature is 60°F, you still need lots of bubbles and a “good bacteria” supplement like Hydroguard to prevent root rot in many cases.
Make sure to always keep the Rapid Rooter moist but not soaking wet.
Most seedling plugs will go back into place easily, and you’ll barely be able to tell it’s been opened
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.
Now that your seedling in in the tank, it’s time to learn how to….
These seedlings are a few weeks old, and the grower plans to move them all to the
I thought hydro plants liked it cold?
You’ll start to see the seedlings’ roots coming out of the bottom of the cube, and this is the sign you’ve been waiting for, as it means you can start transplanting. This can take about two to four weeks depending on what plants you’re growing.
The first is that you’re limited to what you can grow in your system. You have to choose from the options available at the store. However, if you start your own seeds, you can grow anything. This means you can grow your favorite heirlooms or even rare plants that aren’t found at many nurseries.
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.
Step by Step Instructions for Sprouting Seeds in a Hydroponic System
Keep your tiny seedlings growing strong with your hydroponic nutrient solution. Once they’ve gotten bigger, you don’t have to make the nutrient solution half strength.
Many people skip starting their own seeds because of the time and effort to get them started, but there are some great reasons to start your own seeds hydroponically. It’s so much easier to just go to the store to pick up some seedlings to pop into your system and get growing, right? Well, store-bought seedlings do have some downsides that can be avoided if you start your own.
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.
What You Need to Start Seeds in a Hydroponic System
The first time you start your own seeds for your hydroponic system may be a bit more expensive at the beginning because you need to buy more materials than in future years. Seeds need water, light, oxygen, and heat to grow. You really don’t need anything too special to grow your own seeds.
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.
