- use a grow light for your cabbage sowings indoors, leave it on 12-24 hours every day.
- put the sowings in a warm spot.
- move the sowings to a cooler space when the cabbage has started to grow.
- keep growing the cabbage under a grow light.
Likewise, can you fix leggy seedlings?
If the soil is warm enough and the seedlings are mature enough to be transplanted, harden them off and get them outside in the sun to keep them from growing leggier. If you have leggy tomato seedlings, the best way to correct them is to repot them (or transplant them) and bury the stems up to the lowest set of leaves.
Similarly, are leggy seedlings bad? Leggy seedlings are not just slightly unsightly. Legginess is often an indication that your seedlings will fail to thrive once they are transplanted. “The other things that happens with the leggy seedlings is that they aren't storing as much carbohydrates,” said David Graper, South Dakota master gardener coordinator.
Beside this, can you plant leggy seedlings deeper?
If your tomato seedlings have long leggy stems, one solution is to plant them deep. Bury at least two thirds of the stem under the soil. This can encourage the seedling to grow new roots along the buried length of the stem.
