started grow question 3y ago
Looking to upgrade my maxibright daylight pro 8 bar led light to something a bit bigger and beefier. Something that has a span of 1.5m x 1.5m and ideally more power. 1000w etc. Any suggestions on what works well and why you like it? Thank you

When turn on the lights?
It's pretty warm here right now already. When is the right moment to turn the light on? It's a dual spectrum 300w CFL under a 470x470 reflector and both seedlings are auto fem. What's the best light schedule? 24/0? 18/6? Thanks

Add on lighting
Hey Growdiaries. I’m about to start my 2nd grow but I’m not happy with my Viparspectra 300 for flower. I want a cheap add on for the flower stage? CFLs look like a cheap, low energy use, add on as I’m only growing two plants in a small w3xd2xh3 ft tent. Any advice plz & 🙏🏼

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

OK to switch from 12/12 to 18/6 for auto in flower?
Is it OK to switch an auto from 12/12 to 18/6 when in flower (2 weeks)? I moved the plants from the attic which was way too hot and tried the 12/12 schedule to reduce the heat. Now that they are in an AC spare room wondering if it would be worth switching. Appreciate the support!

additional blurple lights
I also got the blurple lights from my friend. To keep the temperature down I haven't installed them yet and not sure if I will. Will they make a difference if I add them next to the current LED? If so should I wait until the flowering stage or anything like that?

Lights. Please explain to a newbie
How much light does a seedling need? How many watts? Is it better to have one bulb but closer to a plant, or 4 bulbs and higher from a plant? Does it matter how many plants are under the light if they don't shade each other? Do plants "steal" rays so its better to have 1 plant?

Low Humidity and high temp or high humidity and low temp?
Do you think it’s better lower temp and higher humidity (like 27 degrees c and 80 % humidity) or higher temp and lower humidity (like 29 degrees c and 60 % humidity)? I’m just waiting for the humidifier but in the meanwhile I have to fix somehow. Thanks!

Too close to the “sun”(light).... any advice?
My plant grew close to 4x it’s original size during her stretch, 10-12” on day one of 12/12 to 46” tall. She’s on day 30 of flower and I set up a second ScrOG net. Other than blocking light to shorter plants, do you see any other potential problems this second net might cause?
