In Vegetative Stage should I switch lights to red spectrum as per Grow Bible or is green spectrum best?
If you have a light that has veg/bloom switches, then you should be running both on for the duration of a grow. These lights are typically underpowered and you’ll need to provide all of the wattage you can give the plant for the best results.
Switch plastic planter for 3 or 5 gal cloth bag, IMO.
Good growing to you.
Those seedlings look great, for now.
