You install phytolamps, but the seedlings still stretch out?
It turns out that popular advice about lighting is a myth that is destroying your plants. Find out how lights turn into killers!
Mistakes of gardeners
The first mistake is 24-hour illumination. Plants need darkness to absorb nutrients.
The second is the use of lamps with pink light. They stimulate the growth of stems, but not leaves.
The third problem is the distance to the seedlings. Lamps hanging higher than 30 cm are useless, and lower than 10 cm burn the leaves.
The fourth mistake is ignoring the spectrum. Conventional LED lamps do not replace phytopanels.
The fifth mistake is the lack of a timer. The light should turn on and off at the same time so as not to disrupt the biorhythms of the plants.
Tips and tricks
Turn on the phytolamps for 14 hours a day. The optimal spectrum is blue (450 nm) for seedlings and red (660 nm) for flowering.
Place the lamps at a height of 20–25 cm from the plants.
For tomatoes and peppers, use lamps with a power of 50 W/m², for greens - 25 W/m².
If you don’t have a phytolamp, combine regular cold and warm LED lamps in a ratio of 3:1.
Reflecting light will increase efficiency: cover the window sill with foil.
To save money, install a timer on the socket - it automatically turns the light on and off.
If the seedlings are on a shelf, use reflective screens made of white fabric.
Many gardeners believe that pink lamps are better. However, experience shows that plants grow pale under them.
The blue spectrum of the beam promotes root development and such seedlings produce a harvest a week earlier.
