bridgesii needs lighting

So just got a new indoor greenhouse i was curious as to what kind of lights are recamended for bridgesii cactus both from cuttings and a few from seed. And bridgesii penis plants. I have had them in the window for a while want to keep them growing with lights can someone tell me what kind of lights are the best so i know what to look for?
if possible led would be best so they dont give off lots of heat but would be willing to use otrhers if needed

https://www.htgsupply.com/products/agromax-signature-750w-double-ended-grow-light/#configuration
i was looking at this would be my 1st choice but from reading leds are not great but what i read was from a long time ago....maybe tech with leds has gotten better would this work? or not enough wattage?

If your plants are small just get a T5 shop light from lowes/walmart. Just make sure the bulbs are 5000k-6500k. Either of those HIDs (with a MH bulb) will work for a while. I posted this at another forum it should explain why.
Quote:
As for your seedlings: Depending on many factors (light cycle, fertilizer, watering frequency, etc) you could maybe get away with just T5 shop lights for a couple years. I havent used them much, and not for anything bigger than 6" tall, but i assume you could probably get to 1' or so before you started to notice any decline in grow. Due to lumen/lux/(whatever unit you want to use to measure light intesity) drop over distance being exponential (see Inverse Square Law of light) the amount of green skin exposed to enough lumens for optimal growth, will drop drastically as the cacti increases in height. Thus etoliation. You could add supplemental side light, or even implement a vertical style grow setup, but the energy cost will soon become unreasonable.
As for Adult cacti: I wouldn't even attempt to grow anything over 1.5'-2' inside. Even with HID lighting 18" can be a drastic drop in light intensity. Your cacti will etoliate without careful planning, lots of supplemental light, and a massive increase to your electric bill.
I currently have about 25 cacti ranging from seedlings to ~16" rooted cuttings under a 600w MH. This is just to fight etoliation as best i can in winter as i have no room in my house that stays cool enough to make them go dormant. It might work for this winter, but next winter I won't even bother trying. Greenhouse will have to be built.
In the wild some of these trichs will reach 20ft or more, but the sun does not have a noticeable lumen drop over 20ft. Thus all the green skin can be used for photosynthesis and produce fat and tall columns. Trying to replicate this indoors is futile. It could be done, but i dont wanna be the one paying for that electric bill.

so i have some seedlings both in dirt and grafted those can go under t5 lights i also have penis plants and csome larger bridgesii coming but i plan to cut them down just below a foot and make more of them so ill have alot of shorter ones....what about this light
https://www.htgsupply.com/products/htg-3-0-810w-cob-led-grow-light/ i have one of those i know cacti like lots of blue light so thinking of adding

would the combo of those 2 work for a few penis plants and some collum as long as they arent above 2 foot?

No experience with LEDs here sorry... From what i hear they are loved by some pot growers. Basically anything that will work for pot growers will work for cacti, so maybe look on a pot growing forum to see what they recommend.
But remember no one is growing full sized pot plants indoors. Some sativas can get massive out doors(15ft tall or more). So whatever light you go with don't expect to be growing massive cacti indoors, it's just not gonna happen.
If it were me i would go with a decent 600w-1000w HID system and put it in a room that doesn't get as much heat as the rest of the house. This is what i did(only because i already had the light setup, if i had to buy one i would've just let them etoliate) and the 600w light raises the temp from ~70f-75f to ~75f-80f in a 12ftx12ft room with 7.5ft ceiling. I have just a small cheap inline fan(maybe 30 CFM) to move air through the flow hood to cool the bulb. And i wouldn't try using lights in summer anyways. When it gets warm all plants go outside where they belong
However you said you have a mini greenhouse so LED would probably be better, or a decent fan and exhaust set up.

Honestly 2' may even be to tall they will probably etoliate The "usable" light for optimal growth, even with a HID, is in a ~6"~18" range(depending on wattage,bulb,reflector). Plants will grow when further away, but they will etoliate. And just because the top of your cacti is getting a lot of light, that will not stop etoliation, they need a lot of light to put on that girth.
If you have a room that stays between 35f to 55f or so that you can put you cacti in for winter it will work better for you. Let them grow in summer and rest in winter. But if your goal is to have a indoor greenhouse year round then you probably wont get much advice here. AFAIK most people here don't bother with indoor growing of columnar cacti, they allow them to go dormant by keeping them below 60f or so when winter hits.
Again for advice on LEDs try pot forums and see what they are using, if your willing to drop ~$1000 on a lighting set up you might as well get the best. just remember your looking for vegetative lights(5000k-6500k) not flowering lights(~2700k). Cacti will etoliate under red lights(flowering/HPS).

Honestly tho theres no reason to make this hobby so expensive, unless you want to... Just get some T5s for the seedlings and grafts and let the others go dormant.
If i had the option to let my cacti go dormant i would, but my wood burner keeps this tiny house to damn warm And i dont even have a south facing window to put them in front of

Here are some LED T5s recommended by other trich growers here. For that price im even tempted to buy a set, i have no need for 8 but i could make one

those will work great for seedlings and grafts
When you set them up start at least a foot above the seedlings and lower them slowly, 1"-2" every 3 days or so, making sure to see how they react. If they start turning red back the light up. You should be able to get those 6" or so from your seedlings without burning them, but go slow and see how the react, those lights maybe be too strong to get that close or you could end up with them closer, you will have to experiment. Good luck! and bring those pictures everyone loves plant porn

So quick question for the bigger ones i was thinking about using the 2 lights below. one is ment for bud growing but has more red light than blue so i was thinking about getting the second light below and adding that to the mix to make it blue heavy light. This should work right? Also since the penis plant bridgesii are short should i keep them with the taller cactus (maybe proped up to the same height as the bigger plants or since they are short leave them with the t5?

Cant really say...Adding some red to the spectrum wont hurt(and might actually be better) but you want more blue light. The only issue i see with your plan is setting the lights up so all plants receive the same mix of each spectrum. That product page doesn't really say how much of each spectrum is provided
For damn near $800 you should be able to find a vegetative led setup that will be plug and play.
Yes i would try to get all your cacti level with the light, i used brick and wood scraps to build stands/risers to get them all within a couple inches of each other. the t5 should be fine for a small plant.
Ill say again man, I would just let the big guys go dormant. That $800 could get you a decent outdoor greenhouse and a heater to keep it above freezing. you add a couple of those led strips and you could be pushing $1200. That could get you a nice outdoor setup. Just a thought, there are other ways to spend that money. I got a damn good deal on ~$1500 worth of grow lights and gear for $100 when a friend of a friend had to make an "emergency liquidation". That is the only reason I am experimenting with them.
Before you drop that money i would weigh your options, there is a reason almost no one is growing columnars under lights(other than seedlings and pere grafts)
