Leggy plants under lights Empty Leggy plants under lights

Someone (you know who you are! I won't blow your cover!) mentioned on another thread that no matter what he did, his seedlings grown under lights always get leggy, no matter how close he keeps the light to the plants.

Has anyone started plants inside and have them look like the pictures in the "How to" books?

I sure would love to have mine come out great this year!

Leggy plants under lights Empty a Few tips

Post  SirTravers 3/6/2010, 11:47 pm


  1. Make sure to use full spectrum lighting..mix in a daylight, plant gro bulb with a normal bulb.
  2. Don't use bulbs that produce a lot of heat..LED's are best but costly right now, fluorescent tubes have their size and power limits, metal halide is hot, incandecent...well that's old school y'all.
  3. always keep the lights 2 to 4 inches above the seedlings...this gives an intense light that should slow the plant seedlings growth down to normal and doesn't cook them in the process.
  4. keep the soil moist and warm....think greenhouse environment. You can cover the open trays with perforated plastic wrap to retain moisture while the seeds are germinating.

I've heard of using a fan before, is that for good ventilation, or does it really help strengthen the stems?

To warm of temperatures can cause leggy seedlings too. Once the seeds have germinated the ideal temperatures should be between sixty five and seventy five degrees during the day and about ten degrees cooler at night. Air temperatures that are to warm will cause plants to get leggy, and temperatures too cool will produce short stalky plants.
Crowded seedlings can become leggy also.
