Light specrum for vegetation?
NarcissisticEchostarted grow question 3 years ago
Hello! I don't know science at all)
With which light spectrum bulbs should I buy of these?
I know, that blue spectrum is important, so should it be lights with blue on graphic higher ⬆️ or longer ➡️? I mean these "rainbow" graphics :)
For now I'm having full specrum bulbs (pic 1)

Hello in general for vegetation you must have blue spectrum 6400° K and for flowering red spectrum 2700°K . this indications are write on the box of bulbs. Good luck

You would be much better off buying a dedicated panel LED full spectrum combined grow and bloom light. (ebay/amazon etc)
The bulbs you are showing might be ok for a small vegetative plant, but will not really be adequate for good flower production.

None of them will be great but will do the job. I would pick the second on. Better light spectrum then just red and blue. Fit 8-10 of those onto a bit of ply and wire together. Remember to take the diffusion dome off so not to restrict any light. Good luck and happy growing

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 :)

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?

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 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.
