Helps Avoid Leggy Seedlings The led grow light I bought recently is only 12 watts and my seedlings seem very happy sat under the red and blue lights from tea-time to around 9.00pm in order to extend the daylight hours of the early spring. You can give plants exactly the colours they need in LED form which is more energy efficient.

This might seem like the perfect solution, but you should know that it's hard to mimic those perfect conditions indoors. If you put your sowing in a really warm and bright spot, this should mimic the perfect summer conditions right? After all, this is usually when things grow quickly. You might be able to do this with other plants that take a bit longer to grow, but cabbage usually grows quickly and you need to put the cabbage under a grow light as soon as possible. If you leave the seeds like this, it only takes a day or so before the plants start to suffer. Some people think that they can save some work by putting their sowings somewhere warm (most seeds grow better when the soil is warmed up) and then put their plants on their bathroom floor without any extra light. This is most likely what happened to my friend's sowing. They might have been under a grow light, but probably too far away from it. The cabbage plants grow leggy for two reasons: The first one is that the plants are in a space that's too dark and/or too warm. An unhealthy length would be around 4 inches.
The first leaves might be located only an inch or so above the roots. Worst case scenario, the stalk breaks and then there's really not a lot you can do.Ī healthy cabbage plant has nice and chubby leaves on a reasonably long stalk. It might even start to fold and it might not be strong enough to straighten out and carry the plant. The more leaves grow, the heavier the top of the plant gets. After that, the characteristic cabbage leaves start to grow. When the plant starts to grow, the cotyledons come first. The cabbage plants are in trouble when a long leggy and pale stalk grows underneath the first pair of leaves. That's the way they are supposed to look, right? This sowing looks very different from those lovely chubby plants you usually see in social media. Seeing the sowing like this automatically makes you think that something is wrong.
This is actually what my first cabbage sowings looked like when I tried growing them indoors for the first time. A friend of mine let me borrow some pictures for this article and I'm sure that many of you can relate to what she experienced. If you try growing cabbage indoors for the first time, you will probably notice that your cabbage plants grow quite tall and leggy. Worst case scenario, the cabbage seedling might break. The long and leggy stalks tell me that something is wrong.
