Can you plant leggy cucumber seedlings deeper?

Before you Transplant. As noted above, make sure that your seedling is about 2-3 inches high before transplanting. We also recommend transplanting a seedling after its two “true leaves” first come out. True leaves are the leaves that grow after the initial seed’s cotyledon leaves come out.
Can you transplant seedlings too early?

When should I take the lid off my seedlings?
As soon as you see the first tiny sprout, remove the cover. This allows air to circulate around seedlings, minimizing disease problems. Keep lights 4″ to 6″ above the seedlings.
