Hi I’m no expert this is my second auto grow and I only have 3 grows with photo periods .
I started my light at 24hr @ about 12 inches and the dimmer turned down like 1 or 2 and I’ll test it by putting the top of my hand directly under the light to make sure it’s not to hot I will leave it there until they have 2 let’s of leaves not including first sets of little leaves I can’t remember what they are called. On my first 2 grows I went with the light manufacturers directions and my plants stretched way to much I have a friend that’s been growing for a long time who kept telling me my lights were to high but I was stuck on the manufacturer recommendations so on my 3rd grow I dropped my lights down and went by temp to tell me if they were to bright or vice versa and I was much happier with the results but I wanted a shorter thicker plant and this is what I ended up with Ambrosia (photo)
And I can’t wait to see how these girls turn out I have 5 Wedding Glue and the bottom left is Purple Punch ,the Wedding Glue went in the soil on 11-4-22 and the P.P. went into soil 11-5-22 they are in roots organics formula 707 soil , I haven’t added any nutes yet I’ll probably start my nutes next week at 1/8 strength and gradually increase
I hope I was able to help some
