Good to leave any light you have, but I would recommend placing you HPS horizontally for max light to the canopy. Cheers

Sure leave them. Just don't break them they have mercury in them. Toxic stuff.

Light Distance - 3 plants are taller than the others...Hi all. So I have 6 plants with a 400w HID. 3 of them are about 10-15CM taller than the others. My light is currently about 45CM from the top of the tallest one. Would this affect the shorter plants negatively? Should I raise them to the same level and up the light to 60CM ratherWeek 5

Advice what lamp for vegging.High guys,
My Jack Herer will move soon to a closet with a 60x60 cm surface.
For flowering I will use a 180 watt Hans Panel.
And I do have 2 led lights at home for vegging.
My first option is the Spectrabox.
And my second option is the Cree Cob led.
What is my best option?Setup. Lighting
