I'm really wanting to have a good setup for growing my succulents and cacti (and a few misc. plants) indoors year around. Living in Saskatchewan, Canada makes it tough for much outdoor gardening, and having some greenery year around keeps me sane. nodding

This is what I'm working with right now. All the lights I have now are these full spectrum T5 bulbs.

The lights are on a timer, and turn on at 7am and off at 11pm, and get little to no natural light in their location. What is the ideal distance the lights should be away from the plants? What time of year should I adjust how much light their getting and is what I'm giving them right now sufficient? I haven't increased the light since spring started and they were getting the same amount all winter.

I'm planning on purchasing more lights as my collection has expanded and some areas are rather dark. I've read a few times that 3000k bulbs are the only way to get succulents to flower. Is there any truth behind this? If so, would it be beneficial to have one 3000k and one 6500k on each shelf? Or are there better lights I could get?

Any suggestions on improvements for my plant babies would be greatly appreciated. Thumbs up And I'd love to see everyone else's indoor succulent set up!


Thank You!

That is a nice display you have set up. I can't give any good information on the lights. I do have some plants under lights in my basement but I use standard T 12 shop lights (fluorescent) with daylight bulbs I run them 12hrs on a timer.
Plants are like that little ray of sunshine on a rainy day.

From the way your plants look - they look great! - it would seem that what you are doing is working very well, so I'd say keep doing what you are doing.

The compromise that I have with my wife is that I keep the cacti and other succulent outside (which is of course no problem here in the Valley of the Sun) and she will not complain about my plant hoarding behavior too much, but it has meant that most of the house plants we have are now reasonably to very realistic artificials... So I cannot really give you much useful advice when it comes to grow lights or share pictures my setup.

However, I know that several people I interact with on a different website are really happy with Mars Hydro LED grow lights, but one issue with those is that they have wavelength specific LEDs so give off colored light, easy in a basement, not so useful in a living space, also a little more expensive than what you linked to.

While I am sure that sufficient light is important for plants to flower, other considerations are temperature and nutrients, but I am sure other people that use grow lights can give you better advice when it comes to that.

Hi Bumbly,

Those are beautiful plants! And look very happy.

There are three primary types of color temperature (Kelvins) for lights: Warm White (2700K – 3000K), Cool White (3500K – 4100K), and Daylight (5000K – 6500K).

Warm light has a yellow tint while cool light has a blueish tint. Daylight is full spectrum sun light. I don't know what K rating your bulbs are now - your plants look healthy and happy. The true test is if they bloom.

I would use lights in the 'Daylight' range for cactus and succulents.

Thank you! Smiling bulbs I have now should all be 6500K. I have had a few plants under one grow light for about a year now and have never gotten any to bloom. Any bloom these guys have now are because they're newly purchased from a greenhouse lol. Sticking tongue out

Thank you Big Grin
I'm lucky that my roommate and boyfriend don't mind the plants (they're in our kitchen, definitely not out of the way at all haha). I will check out those lights regardless, maybe will get one down the road and do a bit of an experiment to see if one seems to work better.

I have good growth with all 65k t5ho's on 14hrs a day. I have a LED bulb that is making some spider plants grow like crazy.
