started grow question 6y ago
What ppfd do you guys recommend for plants in veg? I’m finding that my light can be too strong at max power even at a 24” distance.

Put your hand under the light at the height of your canopy., if your hand feels comfortable under the light for 1 minute then your girls will be fine. Cheers

Grow Light for 3x3 tent
Looking for a good grow light for a 3x3 flower tent. -Price is not an issue -Low heat since I am venting into my living area. -Even light distribution. I plan on doing a SCROG so having the same light intensity on the edges as the center would be best.

HLG 550 V2 RSpec power/height in flower
I’m using an HLG 550 V2 RSpec in a 3x3 tent over one Universal Kush plant. Anyone have experience growing with this light in a similar setup? What’s the best height from plant and intensity level should I set the light to? Don’t want to stress her, just want ideal light levels.

Is that just a light burn or could it be something else?
One bud in the middle of my plant is much lighter than all the others, which all look healthy and green. I think it was due to the too small distance of my light, which was only 20cm (8") between canopy and light. I have now moved the light to 35cm (14"). What are your opinions?

Hey Growers. So I made a dumbass mistakes…..for the last 18 days I have had my light timer set for 12 hrs 15 mins on and 11 hrs 45 off. They are looking good and budding up. I’m wondering is that close enough to 12/12 to have my day 1 flower be true for accuracy sake. Thanks

Currently running my KingLED 2000 with both Bloom and Veg switches on. Is this the correct time to go just with the Bloom lighting? There's no harm in running both throughout; correct? Except to the power bill of course. Any thoughts?

Added a light, how far should I hang them both from the girls?
I have added a Mars Hydro TS600 to my tent along with the Spider Farmer SF1000 in my 2x2, how far should I move them up away from the plants? I'm guessing I don't want them as low as the SF1000 was on its own which was around 15" Thank you lovely people!

Which of the two options do you choose and why: Option 1: 1440w over 40sqft giving 36w per sqft Option 2: 1440w over 48sqft giving 30w per sqft. The difference is an extra 2x4 of grow space. Do i go for more lumens or more plants? This is my first LED setup

Wrong light schedule
Screwed up light timing. Thought I was on an 18/6 schedule in my tent but apparently it was 12/12 from weeks 3-7. It’s close to needing to be switched over to flowering size wise. I switched over properly to 18/6 two days ago and plan to keep it there for an extra week. Yes?

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.
