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?🔌🔋

Side lights ?
Would my plants benefit from these extra lights hanged to the side? Photos included of light and how they look. Above are two SF1000D lights. Curious if these will help the under growth or if it's just a waste? Thanks for any info anyone can share . Happy growing!

the light came on by accident at night
Здравствуйте! Случайно во время сна включился свет в гроубоксе на 10 мин. Слишком ли это пагубно для двух автоцветов? Не станут ли гермафродитами?

Grow lights
Does this look ok? I have 2 plants not growing as fast as my macchiato plant. The other two are different strains, Runtz & Zittles. I don’t want to over do it but I know light is key so I thought I’d ask. Both 1000 watt uv & the other is led. I’m on veg week 5 of all 3.

Are these LEDs good?
What do you growmies think of these lights? They're LED's, I have 2 of these going and a few other lights. These though, I don't understand much about electrical info. My green seems to like them ok but are they good? I know to the experts out there, this probably seems dumb, but

Seedling growth rate
Plants grow almost 1 cm per day (3rd week). Is it too little or correct? I have the impression that they still lack light (the rods are quite thin and long), maybe I should bring them closer to the LEDs?

Lights died
So my lights died last night. Would a 2000 watt be good for a 4×4 tent?

Leaves "praying" after lowering the lamp
I am in week 4th of flowering Laughing Buddha, 220W LED ~60cm from tops. Today I have lowered the lamp and the leaves started "praying", on one (higher) plant the other, mostly-indica Holy Punch seems unaffected. I am curious, is there too much light or sweet spot and it's good?
