so my seedlings(3) are about 2 inches tall...what is the closest i can get my 400 watt MH without hurting my babies? steching is a big fear of mine in my system
i also had questions about the distance from a 400w hps. so you say after the third healthy node you can have them as close as 18 inches aways. i was paranoid and have had them 3 feet since seedlings.The light was five feet when the seeds where planted. The light remained there until all the seed casing have cracked; expsoing the first set of leaves and just starting to work on there first set of TRUE leaves. From then I start to move the light down. Aprox. 1ft per day. The distance you move the light depends on your plants growth. For example my babies have three heathly nodes and the 400w is 11 inches away...they are eating it up!! They are 9 days from seed. Hope this helps
