So I have 3 auto want to run a photo to try …. I been doing so well with autos guess I’d try some photo so my auto are 3 weeks old and my photo just germinated. My lights have been on 20/4 and I’m wondering if I can run that on photo as well till I flip to 12 12…… ![image](https://global.discourse-cdn.com/growingmarijuana/original/4X/7/5/c/75c5acb790dff1053c8b104098ffacb131f114ce.jpeg) ![image](https://global.discourse-cdn.com/growingmarijuana/original/4X/e/6/e/e6e923a98a71bbc00b92d4309b275283d1602606.jpeg) ![image](https://global.discourse-cdn.com/growingmarijuana/original/4X/5/3/1/5316121c7dde778c7846784906c3c71354f78b91.jpeg) ![image](https://global.discourse-cdn.com/growingmarijuana/original/4X/9/4/b/94bfc4fc51c749c4d712211612cb845c6f7fa750.jpeg) ![image](https://global.discourse-cdn.com/growingmarijuana/original/4X/f/9/d/f9dafa5a9b06120e03359fac75ad49b62a279cea.jpeg) ![image](https://global.discourse-cdn.com/growingmarijuana/original/4X/d/5/b/d5bdd5e20766bae284c789503fb70c9e9a7e1da6.jpeg) ![image](https://global.discourse-cdn.com/growingmarijuana/original/4X/9/a/2/9a293a3c2affbba126840107d25e156b1dae6245.jpeg) Last two grows gsc ilgm and gg4 ilgm ---

Welcome nice looking plants , I run 18/6 till I flip With photos and autos , I’m sure 20 /4 would also be fine. 👍✌ ---

Definitely can but I’m a 18/6 guy. The biggest auto-photo transition issue can be light leak. Be very through on making sure you’re good there as you really don’t have to worry about that with Auto’s. I have a strong feeling you’ll be just fine! Auto’s looking sweet! ---

Yeah you can run that schedule. Heck you could run the light 24/7 until you flip. But there is some debate on what a resting period does for your plant. Ps those are some huuuuuge nugs!!! ---

> [@BradsBudsMT](#): > > But there is some debate on what a resting period does for your plant. This plant has only had 4 hours darkness it’s entire life, due to power outage. Shouldn’t be much of a debate. Although there isn’t a lot of good reasons for most to run a 24 hour light schedule either. ![20210921_203335](https://global.discourse-cdn.com/growingmarijuana/original/4X/f/4/2/f42400d6aeff5be0f3732817e802ad89b0b42df6.jpeg)
