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.
How many lumens do tomato seedlings need?
7000 to 7500 lumens per square foot is ideal, with up to 10000 recommended during flowering.
How much light do LED seedlings need?
Seedlings need 14-16 hours of light every single day, without fail. Don’t leave them on for 24 hours a day though. Like us, they need to rest at night. So plan to keep your artificial lights on for 14-16 hours during the daytime, and turn them off overnight.

Between 400-600 PPFD: This is great for early to late stage vegging cycles. Between 600-900 PPFD: This is great for the flowering, fruiting, or budding stage of plants.
Do you water seedlings everyday?
Seedlings aren’t able to store water for very long, so they need soil that is constantly moist. This means watering them a few times a day, depending on how quickly they dry out. Test your seedling’s soil with the end of a finger to about an inch deep. If the soil is dry, your seedling needs water.
