Does my LED need more red spectrum for flowerin?
SaltCitystarted grow question 3 years ago
I have an HLG 100v2 LED grow light at 4000K. They say 3000K is better for flowering. Does it make any sense for me to add some cheap red LED strips to add red spectrum? I’d rather not buy another more expensive light if I can just supplement this one. See picture.

Yes it makes sense to help out. Spectrum is important, and closer to 3000K would be optimal. But the more I’ve learned about lighting from Bruce Bugbee, the more I place importance on photon flux - essentially the “strength “ of your light.
If I had to pick (for example) a light capable of 1000 umols/sec/m2 at around 4000K
Vs
A light capable of only 500 umols/sec/m2 at around 3000K
I would certainly choose the first.
Anyhow.. yes the red should help to some extent. Certainly can’t hurt it. Plants look good, and it’s your first grow so I’d just see what you can do with the set up you got during this grow, then adjust if necessary

Red coloured LEDs are very different to LEDs that put out light in the red spectrum.

How to manage a tall plant with a thick stem in week 1 of flowering?One plant I ordered online was pre-grown. Now, it’s about 20 cm taller than my other plants. At the top, the taller plant gets more than 1000 PPFD, while the lower canopy gets about 500 PPFD. It’s currently week 1 of flowering. The stem is too thick to bend down.What would youdo?

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

Do you lower light intensity and temps towards the end of flower?So I’m in mid flower, start of week 7 to be exact. I’m curious on when you guys start pulling back light intensity and going with a little cooler temps. I’m 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

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.

Will increasing light intensity restart stalled seedlingsSeeking advice from Mars Hydro TS1000 growers. When do you increase light intensity during seedling stage? I've had the light 30cm above the plant at 25% power since germination. The plants stalled 2 weeks ago. Can I get them going again by raising intensity or will I fry them?

Hight ProblemsI’ve got 3 plants in my tent, but they’re all different heights. To compensate, I’ve 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. It’s my first indoor grow with this setup and I’m 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!

UV LED slowing down growth? Sorry previous question without the question!The plant has a rectangular area in the middle where it is not growing as quickly. The difference is almost 10cm. I suspect the lamp. Could it be that the centrally installed UV LEDs are causing this? They should grow more inside because of more light.
