When starting seedlings inside under a plantlight, is the light to be kept on 24/7 or turned off @ night?

I'm growing about 150 sweet pea seedlings.


Thanx.

Off at night.

Reply:If you have a timer set it up for 16 light/8 dark,otherwise try to keep track and give them some "night". I live in SE Indiana and am sprouting solanaceae seeds(tomato, chiles, datura) I am in zone 5almost6 and have found that sweet peas like it a little on the cool side so, depending on where you are, plant some direct to site and don't let your seedlings go to long under lights.
Reply:i turn my lights on before i go to work and before i go to bed: tomatoes peppers coleus petunias impatiants begonias but i just can't see starting a pea legume inside. the pea family is so quick to germinate and a vine that needs support almost as soon as tomorrow. no lights are only to substitute day hours then the plant needs to expire rest. god bless
Reply:normal light -turn off at night
Reply:Your light should simulate the natural sunlight. You might consider purchasing a timer for this purchase for your plant lights. Hmm, I bet you could have put the sweet peas straight into the ground. They can handle a little frost.
