How to turn weak seedlings into powerful bushes?
Regular baking foil will do the trick, and it will also save you a significant amount of money.
Experienced gardeners have revealed a method that is forcing all plant growers to remove reflectors from windows en masse.

Previously, their budget was bursting at the seams because of expensive lamps - a lot of money per season was spent on equipment alone. Now the same result is achieved with a penny roll of foil.
It allows you to get strong plants with minimal costs.
Tomatoes with such reflectors are 30% stronger than their counterparts without backlighting: the stems are thicker, the foliage is denser, and flowering occurs earlier.
The foil works like a mirror, redirecting every ray of light to the plants. The frame of 40 cm high slats, covered with shiny material, is assembled in an hour.
It is important to position the screens at an angle of 80 degrees on the sides and 30 degrees on top - this way the light evenly covers each sheet.
On cloudy days, the system adds up to 40% illumination; on sunny days, it prevents burns if the upper reflector is removed in time.
The savings are obvious: phytolamps consume 50 W per hour, and foil does not require electricity.
Ventilation at temperatures above 25°C and adjustment of the screen height are the only requirements.
The seedlings do not stretch even in February, when there is a catastrophic lack of natural light.
The method is already being tested on peppers and eggplants - the first shoots confirm that foil is superior to technological analogues.
