My grow lights setup

Wikipedia on grow lights:
 "A plant's specific needs determine which lighting is most appropriate for optimum growth. If a plant does not get enough light, it will not grow, regardless of other conditions."

"Grow lights usage is dependent on the plant's phase of growth. Generally speaking, during the seedling/clone phase, plants should receive 16+ hours on, 8- hours off. The vegetative phase typically requires 18 hours on, and 6 hours off. During the final, flower stage of growth, keeping grow lights on for 12 hours on and 12 hours off is recommended."

"In addition, many plants also require both dark and light periods, an effect known as photoperiodism, to trigger flowering. Therefore, lights may be turned on or off at set times. The optimum photo/dark period ratio depends on the species and variety of plant, as some prefer long days and short nights and others prefer the opposite or intermediate "day lengths"."

"However, it is the number of hours of darkness that affects a plant’s response to day length. In general, a “short-day” is one in which the photoperiod is no more than 12 hours. A “long-day” is one in which the photoperiod is no less than 14 hours. Short-day plants are those that flower when the day length is less than a critical duration. Long-day plants are those that only flower when the photoperiod is greater than a critical duration. Day-neutral plants are those that flower regardless of photoperiod."

my research on the internet says that my plants are short day plants. they should be flowering in the autumn. except monilaria which is notoriously difficult to flower although easy to grow.


 the label on the plant light box said that the light should affect photosynthesis.

Happy New Year!

it's the 4th of january and my living stones have been without watering for 18 days. 1 of the conophytum plants has gotten wrinkled but plumps back up the day after watering (the 5th of jan.). both of the argyroderma however have completed their leaf change. 1 of the lithops plants is in the middle of changing leaves. another one has grown the new leaves next to the old ones instead of splitting properly. all of the monilaria plants are splitting as well. so far none of my living stones died because of the extended drought. the artificial day lenght has been 8 h during the whole vacation.

April 7 to 25

i water and fertilize my living stones on the 7th of april and notice that one of the conphytum plants has dried up and died. i watered the living stones just a week ago but it clearly was not enough. on the other hand both argyroderma plants are changing their leaves the second time. on the 9th i transplant the last living conophytum plant to a smaller pot. i realize it's too early but the plant is too tiny compared to its nursery pot. before i transplant my conphytum i remember to rinse the pumice. at this time my conophytum is also finally changing its leaves for the second time - its second set of true leaves. to me the conophytum calculus seem the most finicky of the bunch. only one out of ten has survived this far. i keep the photoperiod at 12 h/day during this month. as i receive guests this month i fiddle with the timer to keep the lights on during more pleasant hours such as 10 am to 10 pm versus 7 am to 7 pm. my guests sleep in the living room so i do not wish to dist...

July 4 to 26

on the 4th of july i water my conophytum plant and begin increasing the daylight hours. on the 6th of july i notice that my conophytum plant has a tear in the middle. i am afraid it is almost bursting because of too much watering. i also increase the daylight hours and the plant lamps are now on for 15 hours. on the 7th of july i water and fertilize all of the other living stones except my conophytum plant. on the 14th and on the 21st of july i water and fertilize all of my living stones including my conophytum plant. it has survived against all odds. on the 26th of july i water and fertilize all of my living stones including my conophytum plant. i also record the temperature indoors + 24 °C. this summer's highest temperature indoors has been + 29 °C.
