600w hps
Wouldnt let me PM. I have a 5ft long 3ft wide 6ft tall white walled grow room and am thinking about a 600w HPS light now. Will this fill the entire room? If so how many plants should I plant? Will this one suffice? Would a 400w hps be more suitable for this space?

LED Wattage confusion!?!?!?!?!
In a few days, I will be putting these into a 4ftx4ft grow tent. Im a little concerned as my Lights say 1000w but on further research, it says actual wattage 140. does this mean I only have 280w and is that going to be enough?

Stretchy seedlings...worried!
Hi, I have 5 seedlings on day 7. 2 of them are going fine but the three from ditch passion were very stretchy though. Likely due to having the light to far away. Take a look, any advise would be great. Cheers all!

I used the photone app in order to get these numbers that are pictured below ! I’m going to research them but I’d thought I’d share them anyway.

Back To 24 Hour Light - Auto Flowers
My autos switched from 24 hour light to 16 about 2 weeks ago to see if it would help make them bloom faster. Can I turn them back onto 24 hours or could that mess things up? I would like the most amount of light time. They should have 2 more weeks left

Grow Lights
Is it okay to use an LED Light 1000 watt (4x4x80" tent) & a UV Light 1000 Watt in a 4x4x80" grow tent for 3 plants. I want more light, I have plants growing slowly so I'm hoping to adjust the amount of light I have would speed up their growth. LED is white spectrum & UV blue-veg

Invert light/dark during a grow
For veg period is better if I start with light on in the day, and off in the night, but for bloom period it will be too cold, can I invert light/dark during a grow? I will have light on in night and light off in the day.. does the plant have any problems if I do that?

Change lights off time?
I'm having trouble with temperature control. My nights get too cold. My current lights off time is 12am-6am. Is it possible to change it? I really want my lights off to be from 9am-3pm. I think that would help me a lot. How do I change it? Let my lights run for 27 hours?
