Looks ok. Using bottom range 301b leds, kind of like spider farmer and mars hydro... Not tightly packed if I'm being honest. Would be good for a 3x3 - 4x4. I wish you luck in your future grows

Switch Fixture During Bloom
Plant exceeded growth expectations. Now the light penetration is not at the desired PPFD half way down this crowded plant. Any reason not to upgrade to a 250 bar light during flower with Autos?

New update got my new grow light dialed in.. And the nutes helped a lot seen more growth in one day than I had in the last 23 days! I am worried that if I place the light at the recommended height (6”) that would be too much so I’m running the lights at 50% power and at 12” away

Grow lights
I'm currently looking for a new grow light. But it's crazy how many choices there are. Since my grow area is very small, 40x40cm or 1x1', I don't need a lot of wattage. So would prefer to invest in quality over quantity. Any suggestions?

Anyone familiar with using the lux light measurements with full spectrum leds? I've got the free app on my phone and read some online guides but any advice or shared experiences would be helpful.

LED light - Veg / Bloom
Hey guys and girls, I have 2 autos that are a week old and looking strong. I have a Phlizon 600W Led light which comes well recommended. It has 2 switches. VEG & BLOOM. You can have 1 or both on. Should I have both switches on (full power) at this early stage or just VEG?

LIGHT SPECTRUM, is that a good one for growing cannabis?
Hi guys, in the future I plan to upgrade from the current 2x2 box/150w LED. I was thinking of a 4x4 area with 500w LED. I came across an interesting 500w led lamp for quality/price and this is the spectrum chart, does it seem suitable for growing cannabis?
