Germinating seeds in soil...Seedling photoperiod question

So I'm germing in soil....and I have my lights on in the tent to keep the temps up in the 70s. The lights are on 24 hours (all the time duh).

However I have my first seed germing now and I'm wondering if any damage can be done on a 24 hour photoperiod as opposed to a 18/6 ir 16/8 cycle....as I'd like to leave the lights on to keep temps up to germ the other seeds (hopefully anyway).

Any input is appreciated....first time growing tomatoes.

Yes you can leave on 24/7

Their are a lot of growers who does this tho help keep short and bushy , although im not 100% sure if it works since iv never grown 24/7

Thanks Goten +rep

24/7 doesn't incorage root growth and doesn't give the plant time to rest. you can do 24 till they pop out of the soil then go to 18/6 IMO

Yeah leg, I'm only doing that till they pop, then I'm going 18 through veg
