What kind of light level (lux) during the dark cycle will cause my plants to herm in the flowering stage?
What kind of light level (lux) during the dark cycle will cause my plants to herm in the flowering stage? I am growing in my bathroom (no windows) and I am worried about external light entering. My bathroom has 3 LED (30W) bulbs in, I have removed the 2 closest to my plants.

Hello I wanted to try 2x Strawberry Pie Auto from Fastbuds soon. And I'm unsure about my equipment. All the data I can give you is in the picture! Is the 300w lamp too bright for the tent? If the lamp is fine, how high should I hang it?

Short plants in flowering
Flowering started but the plants still seem a bit short. Maybe too much or too close light? Or something else? Tried avoiding light off because its hard controlling the rise of humidity.

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 & 🙏🏼

LEDs for 32x32 tent
New to indoor growing. Set up a 32x32 Vivosun tent. Currently have a giixer 1000w light, but wasn’t feeling the coverage was good enough for several plants. So I just ordered a second one. Do you think 2 giixer 1000w leds is ridiculous overkill? Any thoughts appreciated.

T5 vs. LED for veg?
So I have a T5 light, and I’ve used it to veg quite a bit, and it does really well. My question is, should I use the T5 in just the seedling phase, then use LED for veg and flower? Or will the T5 give me good results throughout the veg cycle?

Сколько ватт на 1 кв.м LED
Can you tell me how many watts of LED light are needed for 1 square meter? What's the minimum, what's the norm, and how much would be bright enough to really see? The lights are 500w for 100x100cm LED. TENT 300x300, and how much exhaust ventilation is needed in cubic meters? I'm planning on using TD Silent.

PAR/PPFD and light height
PAR/PPFD: does light height matter if your PPFD is in the right range? Another way to ask: is 300 PPFD @ 2 feet the same as 300 PPFD @ 20 feet, or are there other factors involved? (assuming heat, C02, all other non light inputs equal)
