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.

How much light - PPFD - without CO2?
How high in power should I go with my lights without CO2 enrichment? I can comfortably provide 1200 PPFD to the canopy, but I'm holding it down near 900 because I'm not sure the extra power used would yield an increase in, um, yield.

Less light for an auto? Maybe 12/12?
Been going with 18/6 for my cream autoflower from growers choice from Day 1. Now 5 weeks into flower I’m wondering if she would benefit from less light, like 12/12, as you would for a photo period plant. What do you think? Would she be happy flowering in some more dark period?

How can I reduce the heat in my 5x5 tent (650w light bar/6" ac Infinity and a ton of fans) without AC? Do I have to leave tent open?
5x5 tent is in a kind of lung room (utility room) that stays around 20C/68F. The tent always seems to be at 30C86F with lights on. Ive added and moved fans, opened more intake vents. I have AC, but its -25C/-13F outside. Id like to drop the daytime temp 5ish degrees for flower.

Light distance for Seedlings
My question is my 2 seeds have popped out and I am using 3- 8.5 watt 5000K LED lights to light them up. Both plants are under humidity domes so how far should I put the lights above them? I have them in a make shift grow tent for now as my regular tent is finishing up a grow.

Light: much Power less hours
Hi everyone, I'd want to decrease the hours of light to give the plants the impression that winter is coming, but I'd want to add a led to increase the power of the light. Can I apply both this ideas? Thank for your attention

100W full spectrum enough for 2 plants in a 80x80x160cm tent. Should I get a 300W instead?
So, I bought this light, it's a 100W full spectrum grow light. But I think I might've bought it too hastily. I want to ask you guys before I return it though. Do you think I should get a 300W instead? Planning on growing 2 auto plants ScrOGed.

Changing Lighting Schedule
The days on the plants are since planting, so i was going to keep the vegetative light schedule until 5 weeks since planting, then start moving towards a 12/12. Is it even optimal for an autoflower to have a traditional 12/12 lighting schedule during flowering?

Where am I going wrong? Beginner, SSH, RDWC, 100 GAL, SF4000 etc.
So I am super excited did a bunch of research built the system and considered every factor I have come across. I am now into Week 3 from when my seeds popped and I am just sick of seeing them small. I don't understand where I am going wrong

Alright so this morning from 8am to 4pm my power was out. I transplanted last night and soaked the medium pretty well. Will this power outage hurt my girls. Did the temps being 10 degrees lower all day hurt them. How soon will I know if I get root rot or anything of that nature?
