Bagseed

@jovialmusic once they are past the seedling stage you can have them fairly close say 10 inches

Depending on manufacturer etc. and are you vegging or flowering. But I'd say you good now. If she looks good and bushy. Not get lanky and tall. But also won't stop growing up then it's too close. Happy growing!

Look at the manufacturers recommendation. For 150 watt LED I recommend 30" for the first week -10 days, then down to 24" and let her grow towards the light. Watch how your plant responds. If she is stretching and getting leggy, lower the light. If you see bleaching of leaves and other heat stress signs, raise your light. Happy growing!! 🍀🍀
