Green Light Bulbs - fluoro tubes
Apart from the junk shops, a number of craft shops sell paint for painting
designs on light bulbs or glass. If you covered the bulb with this green paint you will have green bulbs. You can often buy painted bulbs at markets, get the seller to do a couple for you in green only. Hope this helps, Peter "rapdor" wrote in message ... Thanks for the illuminating lesson. But I have apparently not made myself clear. We are going to grow the seedlings in total darkness, ie., we do not want light for plant growth. We want to exclude all light. But of course need to see what we are doing. Green light does not affect plant growth, so that's what we need. Such a product does exist, I'm positive. But where to find it, that's the question. |

Are you doing this as an experiment? I didn't know of any seedling that will grow successfully in total dark, or is there something out there?? :-) -- Remove "not" from start of email address to reply |

I didn't know of any seedling that will grow successfully in total dark, or is there something out there?? :-) No, its not an experiment, its a commercial operation, growing tens of thousands of avocado trees each year. But this is the first time doing the etoliation (darkroom growth) on a large scale. That it works, and how it works is established knowledge. Just sourcing the damn lights seems to be a problem. |

That it works, and how it works is established knowledge. Just sourcing the damn lights seems to be a problem. I forgot to add that we grow avocado from seed in the dark (until the shoot emerges) as a matter of course, thousands and thousands of the little devils. By keeping them in the dark and at constant controlled temperature, it reduces the germination time from several months to several weeks. But this enquiry about the green lights relates to returning grafted seedling (about 30 cm tall) to the darkrooms to clone additonal plants from the grafted growth. Its all a bit space age, and I'm just a humble worker in the whole process. It's very interesting work. |
