I would not buy these. You would need a whole lot of them to amount to anything. Be better to buy a budget growlight off Amazon.

Height Spider Farmer SE3000 week 5 flower
PAR increased to 600 PPFD, done by lowering the light to 35 cm above canopy. What do you think? is that too low? I'm using a Spider Farmer SE3000 (300 Watt). Anybody experience with this light? How high did you hang it from week 5 of flower to the end?

Pruning?
Pruning ideas along the stems? Was thinking that some of the branches at the bottom that may never get over the lid of the pot should be snipped off. Also, good idea to keep blue/red light shining under the canopy?

Can I use 18 on 6 off during flower when growing autoflowers and using ViparSpectra KS5000 LED at 100% power?
I have a tent with a ViparSpectra KS5000 LED lights. If I am growing autoflowers and they are in the flower stage do I have to change the light/dark schedule from 18 on/6 off to 12 on/12 off or will it be ok to keep the lights on a 18/6 schedule since they are autoflowers?

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

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?

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.

I have a 3-chip 1000W LED with a max output of 180w (Veg 125w, Bloom 55w): I'm growing autos in a 2x4x6 tent. I'd like to grow 3 plants at a time. Do I need another grow light? Will the one I have suffice?
