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

Should I switch to 12/12 lighting? - Autoflowers not showing pistils after 5 weeks
Growing five plants (germinated Sept 8) including 3 Anvil and 2 BlackStrap autoflower strains from Mandalorian Genetics. The BlackStraps have been showing pistils since about end of week 3. No Anvil plants are showing pistils. Should I switch the lighting schedule to 12/12?

Ventilación y Luz en plantulas
Me inspiré en McGyver y he puesto un armario improvisado... Cómo de importante es la ventilación en esta etapa de plantula?🌬️ (He dejado la puerta entreabierta por las dudas)🤔 También he puesto otra luz auxiliar..se notará en el crecimiento o desperdicio luz?🔌🔋

Mars Hydro TS1000 hanging height
People with experience using the MH TS1000, between 24"-30" at 25% seems like a reasonable height to put my light over the plants in initial vegetative state at my 2x2ft tent? Thank you! :)

Bad idea?
Will a mars hydro TS1000 be too strong for a 60x60x140cm tent? I have been using a TS600 and TS1000 in tandem in a tent 4x too big for the light level, I have been growing strong and tasty buds but with low yields so downsizing my tent size to maximise the light.

Does my LED need more red spectrum for flowerin?
I have an HLG 100v2 LED grow light at 4000K. They say 3000K is better for flowering. Does it make any sense for me to add some cheap red LED strips to add red spectrum? I’d rather not buy another more expensive light if I can just supplement this one. See picture.

Is my LED too close or too far from my plant?
So this is my first grow and it feels like she’s growing a bit slow. Currently at day 10. Distance was 62 cm. The LED is 100W. Now the distance is 57 cm. I’m wondering if I’m just impatient. Is this distance appropriate? How is the growth looking?

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!
