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.

3000 watt power use
This is my first time using such a powerful light in my opinion, 3000 watts seems overkill but that's what i want. The question IS, is it better to have 1-2 plants under the 3000 watt or worth it to manage 4 at a higher distance? Cheers. Don't keep techniques in mind.

LED glass/plastic cover.
Glass/plastic cover on cheap led lights.. do you remove them or not? From keeping reptiles I know that any glass/plastic will reduce UV. Just wondering if anybody's noticed any difference after removing the glass.

Come to my aid
Yooyoo guys could this be light stress ? Also should I consider a second defoliation? I reckon it could help the shorter plants get more light What do you guys think ? I’ve added a pic of the light Happy growing

Leaves up?
Hey Guys 👍🏻 Quick question, I have my light (HPS - 250w) 40 cm above the plants - should I get the light lower? One of my babies has the leaves going up. I guess she is enjoying the light but I have doubts regarding the light distance.

Hi first time grower here. Been vegging 4 plants in 80cmx80x160 tent with 150W LED (Mars Hydro TS1000). Start of 2nd week flower today and I added another 150W LED. Could that potentially increase my yield? Thanks!
