Hi, I have a 2ftx2ft grow tent and using 2 x 2ft T5HO 24w. (picture)
I placed my seed in root riot for germination 3 days ago and it is now at this stage. (picture)
I have a couple of questions regarding the light setup:
1-How far should the distance be between the light and the seedling at this stage and how does the distance change as the plant grows (if you can provide a timeline)?
2-At which stage of the plants growth will the T5 HO turn obsolete and what should I replace it with?
I have a chinese Bestiva 600W double chip that I bought as it's cheap and don't have a big budget, but I don't know when to use it and how far to keep it away from the canopy.
