I introduce my environment for culture in my room in Japan. Note that this is just reference.

Cultivation technique may be depend on each species. Some good books will provide cultivation information for each species. And information of authigenic region (ex. climate, altitude, and authigenic location) will help to estimate cultivation, if you couldn't get cultivation information for targeted species. See the LINKS AND BIBLIOGRAPHY page for reference.

I roughly classified with following cultivation groups.

  • Light to Sunny
  • Half Shaded
  • Shaded
    TEMPERATURE (Yearly; summer, winter)
  • Hot (35-15oC)
  • Intermeditate (28-15oC)
  • Cool in winter for blooming(28-5oC)
  • Cold (15-0oC) - not cultured in my room.
    TEMPERATURE (Daily; day, night)
  • High (different about 20oC between day and night)
  • Medium (about 10oC)
  • Wet
  • Mesic
  • Dry

One of most important point to consider your own environment is that you observant your plants. And if it is possible, it is better to corroborate with any reliable papers, books and/or your own experimental trial.

I hope that this page help to find best condition for your own environment.


Automatic lighting control

Air Condition

Air ventilation, temperature, and humidity


Soaking, misting, and nutrients


I'm using some electric lights, which are controlled with timer. If I can get it enough from sun, these are not required. But only one window with frosted glass at east-side of my room is not enough for my plants. So I'm using them additionally.

It may be difficult to culture under electric light for some species which like sunny environment. These species should be located near any window.


Plants and light

Minimum 15cm (about 6inchs) from plants to Yachtlight (100W; 8:00AM-1:00AM). Air flow is required for plants.

Timer Light

24 hours timer controls 100V electric source. (Max 1500W, On/off switching unit is 15 min.)

One of example for light (100W; 8:00AM-1:00AM). Note that take care its high temperature.


Air ventilation Temperature / Humidity
Air Fan Thermometer

Air ventilation in my room is controlled with 24-hour timer. Active 15 minutes in each 1 hour. Don't target directly to plants.

It should breeze continuously for around any window closed with frosted glass, if it will be too high/low temperature, such as sunny time in summer and eary morning in winter.

Air ventilation is very important for effective photosynthesis, because ventilation will help to exchange CO2 and O2 through opening stomata.

Temperature; It will be best between 15-28 oC in a day for intermediate temperature species. hot/cool temperature species are required any special environments with any cage or other.

Temperature in my room (with air conditioner): summer; 20-30 oC (20-40 oC near the window), winter; 18-23 oC (10-30 oC near the window).

Humidity; My target is about 60%. Maybe 70% is best, but it is too high for any room.


Following examples are for Air-Bromeliads.

We must understand Air-Bromeliads bases CAM types assimilate CO2. Keep dry in daytime, misted in night for these plans. Watering in daytime will be cause of killing Air-Bromeliads under sun light.

And you must understand that watering is highly depend on species. Some kind of species must keep dry, and too much watering will be also cause of killing.

Soaking Misting Nutrients

Soaking is in over night with room temperature water. After watering, please take it carefully. DON'T locate sunny place till dry.

Interval between soaking is depend on species of Air-Bromeliads. Most of them are two weeks.

I don't use soaking way for usual watering for Air-Bromeliads. But this is one of good way for them. And many Tillandsia lovers in Japan are using this way.

I'm misting with atomizer or shower in bath room. From spring to autumn, both of them are used. In winter, I use only atomizer.

I tried this every one or two night(s) for most my Air-Bromeliads in about 60% humidity. Please observant your plants, and decide interval. It should be changed for each season. If you want to stop groth in low temperature environment in winter, please decrease watering. If Air-Bromeriads are in heigher than 15oC, most species will continue growth with usual misting.

Temperature of water should be same to room temperature. I'm using 500cc PET-bottles to make water in room temperature for 500cc atomizer.

For Tillandsias, typical liquid fertilizer is 20:10:20 NPK formula one.

I'm using liquid fertilizer for 2 times in a week in misting. It is 6:6:6 NPK formula liquid fertilizer. In growing with inflorescence for blooming, I'm using 0:6:4 NPK formula one also.

One of books, Blooming Bromeliads, introduce about 1:1.5:2 NPK formula for Bromeliads in Bahamas.
