How close should HPS lights be to seedlings?

How close should HPS lights be to seedlings?

HPS lights should not be placed inches from the plants, as you would place fluorescent lights; you should set HPS lamps higher, generally between 5 and 8 feet from the plants.

How far should I keep T5 from seedlings?

T5 Grow Light: Distance From Plants To begin with, hang it about 4 to 6 inches above the tallest plant, for vegging or flowering. The T5 fluorescent grow light distance for seedlings should be a bit further away. I’d start by hanging the light 6 to 10 inches from seedlings.

Can I use HPS for seedlings?

The HPS distance from seedlings should generally be between 10 and 14 inches from plants. However, the optimal distance between an HPS light and seedlings will vary, depending on the HPS wattage, from 10 – 25 inches. For 1000-watt HPS lights, a distance of 5 feet might be needed.

How much light does a seedling need?

In general, seedlings should receive roughly 14 to 16 hours of light a day when situated in a south-facing window. This can be very difficult to achieve, and most growers opt to use artificial lights for their seedlings. These fluorescent lights should be left on for 12 to 16 hours a day.

How far should LED be from seedlings?

There is no universal rule for setting the distance but it’s recommended that LEDs are placed 12 to 18 inches away from the plants. Light is among the most vital factors to consider when growing plants because it triggers the photosynthesis process.

Do seedlings need direct sunlight?

Initially place seedlings outdoors in a sheltered spot – protected from wind and direct sun. Each day following, expose plants to another 30-60 minutes of filtered sunlight. By the end of the hardening-off time frame, seedlings should be experiencing the same amount of sunlight they’ll receive in the garden.

How many lumens do you need for seedlings?

Vegetable seedlings and other “full sun” plants require about 2000 to 3000 lumens (at minimum) per square foot of growing space. So, if you’re growing just a single standard tray of seedlings, using a grow light that emits 3000 lumens is sufficient.
