    Too Much Lumens?

    Hiya Fellow Nepers-

    About 6 weeks ago, I acquired a 10" bical. It is being grown in a 50 gal hex terror-ium (yes, I have a greenhouse, just wanna keep it in the living room where I can see it daily ) with a humidity and temp about 90. It is set very near to a southern window which currently gets whatever sun comes out here in the NW (which is about 8 hours a day).

    I believe its acclimating well, it is almost done throwing out its first leaf for me. But here is the weird thing, so I'm thinking, to supplement its photoperiod with a some artificial light. So I hit it with a 250w CFL grow light bulb at 12" away early in the morning. I go back to check on it 3 hours later, the new leaf went limp Looked like it needed a shot of viagra. So I turned the light off and just let the natural light from the window come through. An hour later, the leaf looked liked the blue pill kicked in.

    Should I just do without the supplemental light, or just increase the light distance? I really don't want to stress it out. What say ye

    Comments, advice, info, experience to pass on?

    Any help woud be greatly appreiated.

    Thanks and good growing

    I bought a cactus. A week later it died. And I got depressed, because I thought, Damn. I am less nurturing than a desert.

    In my experience, my bical is not too fond of strong light. I have 2 T12s about 8-12 inches above it and a T5 about the same distance to the side. It's coloring up nicely but the leaves took a while to adjust to the light.
    I would let it acclimate first by the window and in a few weeks play with the light & distance.

    I grew my lowlanders (N. bical, amp, truncata, etc.) under a 400W metal halide. They like light but they have to be humid. The soil also has to have enough water to keep up with rapid transpiration when getting strong lighting.

    Like any change in conditions you'll have to build up to it if you don't wanna shock the plant, if like me you don't care about it keeping it's old leaves and just want the new ones to start growing as fast as possible, just put it in there and let the plant sort itself out. It'll acclimate itself it just may look a little ugly for a few months while it goes through it's paces, dumping old leaves and growing newer stronger ones. Usually they start out smaller first (but thicker and more succulent) then they get bigger and bigger. More light & feeder crickets = faster/sturdier plant growth. The leaves on my bicals were like leather, with pitchers hard and woody, you couldn't hardly tear the leaves by the time they were huge plants and I had to sell them off. Whereas when I got them they were all soft and floppy.

    Hmmmmm . . .

    Kinda like how I treat my newly arrived VFT's. Just repot them, throw them out into the full glory of the sun, let the old leaves burn and die back, let the plant adjust and let the regrowth begin . . . kinda thing.

    I don't mind doing that to my VFT's but my bical, I felt so sad to see it go limp I will keep your suggestion in mind.

    Thanks for chiming in FReNcH3z and swords

    Yeah that's way too much light. I honestly wouldn't give a single Bical much more than a hundred watts especially if it has adequate natural lighting.

    I would see what the temp is at the plant level after the light is on for an hour or 2...it might be too much heat to sudden.

    Roger, roger their Mark.ca.

    Although I do have a hydrometer already in the tank, I will move it directly next to the plant and see if there are any changes in the temp and humidity.

    Thanks for the suggestion

    Good Growing and Happy Holidays.
