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 rather

Lighting. Increase or stay the same?
Hi, I'm thinking about increasing lighting to 100%... is it too soon? Currently at 60% 20 inches away (manufacturers recommendation.) I'm thinking 100% but staying at 20 inches away.. what's your thoughts? Too soon? (12" - 18" 100% for veg manufacturers guidelines)

Keep LED strip or remove?
So this is a space tub grow, other than the above head light it has a 3500k led strip running around the sides(around 4 meters) is it worth keeping this lighting? I'm only running a 150 watt growstar led ufo, which is fine for my canopy but my bottom isn't nearly as dense.
