Cephalotus setup

Hello gang,

Long time, no post ... let's take care of this.

For the past years, I've been working on a set-up that would allow my cephalotus to bloom. I had some difficulties finding all the information on light amount and dimensions. So, here are the details of my set-up.

Willy help me with the lights. He builds me two 50 watts LED daylight white. The area is 2' X 4' and the high is 2'.

The light are really strong. The ceph are still acclimating to the new lights and are not growing as strong as they did under lower light conditions but some are already looking nice.

If I take light measurement with the lightmeter app I install on my phone and calibrate with noon sun, the cephs get between 7500 and 4500 lx.

The top of the pots are at 23 inches from the light.

Last Autumn, I started an annual light fluctuation. I decreased the light duration at 8 hours per day at the end of December. I'm now increasing it by 1 hour per month. I'll give it a little boost at the end of June to reach 16 hours for 2 weeks then I'll start to decreased it again to reach 8 hours for Christmast.

Here's the result for all this work.

I'm really happy to have flowers under artificial light. The stalk are 16 inches long and the flowers are fully open.

Now, it is brush time :)

I almost forgot the water schedule. Once a week, I fill the plastic bin to the rim and wait a few minutes. With a siphon, I lower the water until the bin is empty. Easily done. That way, I do not put water on the ceph but get all the media wet. I think it also give some air intake around the roots. I'll probably repot some pot this summer and will be able to see if the roots look healthy.

Happy growing!

Very well done @Shoggoths!

I love seeing people put in the little extra effort to make things work. Cephs are actually pretty far spouth of the equator and get a good fluctuation of photoperiod, which is almost guaranteed to be what triggers flowering.

Do you drop the temps at all in the winter?

Thanks @H2O !

A year ago I had a ceph blooming on my office west windowsill. It had not a big temperature drop.

My setup is in a basement. I do not heat my growing room. So there's a small natural temperature drop. I think that in Winter, at night, the temperature can drop below 20C but as soon as the lights go on, the temperature raises between 25-28C for the remaining of the day. If you consider that the lights only stay open 8-10 hours, the plant must feel the difference.

My petiolaris sundews don't suffer from that so ... I don't think it is that much significant compare to the light length variation.

This is wonderful! I am so happy that you are able to get the Cephalotus to bloom!
How about a programmable timer? It could help with adjusting the lighting period of each day.

Yeah, that's great Willy!

Programmable timer could help me with all the time variations. I already have 3 timers but we have a lot of power outage here so I'm often setting them back to the right time. Also, all the timers are on the same period so I would have to get 3 programmable timers ... a bit expensive at the moment.
