Growlight advice please - for living room use

19 years ago

Hi, my first post on Gardenweb! Please be gentle with me. :-) This is a fairly long question, but I thought it best to provide as much info. as possible.

I have one cutting going well and another on the way. #1 has 8 very healthy leaves and 3 more a few cm long, all from the top of the stalk. #2 when it arrives has three mini-branches at the top of the stalk, each with leaves at an early stage.

They are/will be on a heated mat, 32W, on/off/on/off etc. on a timer 24/7. The lighting is currently one Bio Green brand overhead spot per plant, each with a 15W low wattage full spectrum lamp (like an envirolight, I guess). #1 is going great guns with this, but I know that when #2 arrives, I will either need more spots like the ones I have or something bigger altogether.

The thing is, they will be in a small living room, with me there too. The good thing about the dangling spots is that there is no stray light at all. The bad thing is that the light is quite concentrated (and so it is intense), but I will need several more for there to be enough lighting.

My view is this: a lot of spots all dangling at the same or similar heights could almost be a kind of feature in itself. Would look far better than the industrial-looking design of the reflectors that are available. I like the fact that there is no stray light, as (a) I've read on here that it can be dangerous, and (b) I've no wish to get light poking me in the eye when I'm sitting down reading a book or whatever. Who does. And even if I have 5 or 6 of them, it won't cost me all that much to run. But the big question is, would that be enough to produce flower?

The box tells me that each spot gives 891 lux at 15 inches, 569 at 0.5m (18 inches, which is roughly what I have it at now), just 142 lux at 1 metre (about 3 feet). Guessing that lux is the number of lumens, how many lumens/what strength of light do plumeria need to flower?

Although I can place them in front of a window, I might not, and even if I do, it's not like a conservatory or greenhouse and the two plants side by side will be a fair bit wider than the window. In other words, the growlights will be important all year round and will be relied upon to an extent for flowering as well as for even plant growth.

So - what do you good people reckon? I may have answered my own question when I wrote it, but it would still be good to know that I have enough light strength for flowering. I can't wait for that! :-)

    I should have pointed out, perhaps, that I'm living in Cornwall, England. I don't think my frangi's will ever be going outside! It's been blowing a hoolie on and off for weeks.

    I don't know a whole lot about grow lights. I have 1000 watt HID metal halide lights on my plants. All my mature plumeria are now dormant but I do have my cuttings and seedlings that have not gone dormant under these lights. I also keep my seed mats on 24/7 under my cuttings until they have rooted. The metal halide bulbs promote vegetative growth although my passion flowers, citrus and other tropical plants are blooming like crazy. HID sodium bulbs produce a light spectrum that promotes flowering. I haven't had great results with fluorescent bulbs during the winter but my plants go outside when it warms up. Here's a link about grow lights. Maybe this will help or even better maybe someone who actually knows what they are talking about will respond. lol Good luck.

    Hi Freshwater! Welcome aboard!
    Sorry I dont know a darned thing about growlights for plumies as I'm a total newbie at this lark!
    Just wanted to say HI, as I'm also from the UK...(we're a bit scarce on here BTW!)I'm from the Staffs Moorlands area and only have one plumie I grew from a cutting from my rellies in Oz. It was 6in long and planted in April last yr, nothing happened till spring this yr then it grew like crazy and flowered!! Its a Celadine and its dormant now so I just hope I can keep it going this winter.
    Hey! You stand more chance than I do of putting your plumies outside if you live in Cornwall....thats tropical compared to here!!! Ever been to Alton Towers? If you have you may know the type of area I come from. Can see it from the garden in the distance 4 miles away!!
    What types have you, did you buy them in UK or online?
    Good luck, post a msg again.
    Greetings, Greenclaws

    Hi, Greenclaws, and thank you for the welcome. :-) I went to Poly (Uni now) in Wolverhampton, so knew that area a bit in the late 70's.
    Where did you plant yours? I'm guessing on a windowsill? Don't know what a Celandine is, other than that little edge of woodland plant with butttercup-yellow flowers!
    I bought mine from Plumerias UK, which is I think the only UK supplier now. But it's possible to buy cuttings from DJsWay in Tweed Heads. My interest was also sparked from Oz - I lived there for a good few years, up until 18 months ago, and of course love frangis.
    Thanks for your message, too, Karyn. I'll follow up that url. I'm not so sure about having a 1000 watts lamp of any sort in a living room, though. I reckon I'm going to buy some more of the spotlights and group them all together, maybe 5 in all - it could look quite artistic if it's done right.

    Hi again, yes you're quite right..Cela-n-dine is our native cute little yellow plant you refer to, but CELA-DINE is a common, but non the less lovely plumeria variety with a very nice fragrance. It is also more cold tolerant than some of the more exotic types,....(one of the many facts I have learnt from here).
    After several sets of mini leaves coming and dying off and minute root growth, I eventually got it to get going in the greenhouse by placing a cut off lemonade bottle over it to create a mini greenhouse. Once it had rooted enough it put out leaves and also a flower stalk. Have attached a photo to show you what it was like.

    It is currently housed in the living room and has now dropped all growth and gone dormant.
    Where did you live in Oz? We have rellies just south of Freo and have visited them a couple of times, thats where I saw my first plumie and got my aunt to send some cuttings from a neighbour who had 'demolished'' a huge tree in her garden. Only one of the 6 cuttings survived, I lost the others to stem rot before I joined this forum and learnt better!
    Catch you again maybe?
    Regards, Greenclaws

    Hi, Greenclaws. For most of my time there I lived near Coffs Harbour and then near Byron.

    Your pic looks great in the photo. My 2nd one arrives tomorrow. It has 3 branch-ettes, so I'm expecting big things from it. Plant #1 is busy growing 3 more leaves atm. It already has 8, 2 of which didn't exist 6 weeks ago, so I'm happy with it. My only concern right now is that it might be putting out so much greenery because it's short of light. But I'm going ahead with my plan of more low-spread spotlight growlights. I'll have 5 in all, each of only 15w. So not much power usage and it's not going to look like an industrial set-up.

    You pic has inspired me to get those leaves wet and wash off some dust! :-)

    Greenclaws, I might not be checking this forum all that often, so I thought, as we're both UK-based, that we might exchange email addy's? But as there's no way I'd put my email out on here as is (for spam avoidance), it's like this. summerlightinnerpeaceeclipsecouk If you put the at immediately after the "t" and split ever other word (innerpeace is one word) with a ".", you'd get it.
