Light height and brightness
The8thChevronanswered grow question 4 years ago
I have the same light. About 30" to deliver 400 ppfd.
After the second week, you can go down to about 24" to deliver 600 ppfd.
20-22" during transition to flower, then 18" during flower to deliver 900 ppfd.
If you're ever unsure, find the light on Amazon, there's a ppfd map on there. Placement of your plants in relation to the center of the matters. Look up the map and you'll see what I mean, they look like a grid with numbers inside.
If you use CO2, you can go up higher on the ppfd and put the light a little closer.

Looks too close as it's praying already. I use a 100w and a 150w invisible sun boards and put them on full power with a popped seed in soil at 24 inches and it keeps them short and stocky. Each LED is gonna perform differently, just gotta find the sweet spot for your light. I've never relied on numbers or apps, just judge with your own eye and learn from mistakes, you gotta be able to read the plants.

About 2 foot or 24 inches or 50 to 60 mm. On 100 percent. A plant can take up to 2000 ppfd mainly stay between 1100 to 1800 ppfd through my grow space. Good luck and happy growing š²š²š²š

Hight ProblemsIāve got 3 plants in my tent, but theyāre all different heights. To compensate, Iāve hung my light at an angle, so one end is closer to the smaller plants.
My question is: Does this help, or am I better off keeping the light level? Any tips for dealing with uneven plant heights?

Started the plants off with 60 watts. Increased to 100 watts today with a 20/5 schedule. Could I increase to the full 150 watts already or should I give them a few days with 100? Thanks in advance for any advice. Itās my first indoor grow with this setup and Iām still learning :)

Stretchy seedlings...worried!Hi, I have 5 seedlings on day 7. 2 of them are going fine but the three from ditch passion were very stretchy though. Likely due to having the light to far away. Take a look, any advise would be great. Cheers all!

How many plants in a 70x70x160cm tent with 100W?Hello, I have a grow tent kit 2x2 with a 100W 301H EVO Spider Farmer light. I have put there three 11L pots. But now I realize the size/light of my tent might not be enough. Could I manage by adding an additional 60W lamp you reckon or is it best to discard at least 1 plant? Thx

Help with issues IDI have a photoperiod in a 5 gal using BAS light. It is currently day 3 of week 4 , and I'm getting some damage on the tops. Would this be light stress or another issue? The tips are starting to go light green. Using the 200 watt light for the 2x4x8 ac infinity tent.

Do you lower light intensity and temps towards the end of flower?So Iām in mid flower, start of week 7 to be exact. Iām curious on when you guys start pulling back light intensity and going with a little cooler temps. Iām running a 240W S33 from AC infinity in a 3x3.
Should I be going strictly off of PAR or VPD at this point.Setup. Lighting
