recently i came across an article which shows pyramids used for growing plants. it may be dumb for me to post this under adenium forums but i hope my freinds here will believe me. for checking power of a pyramid check out this video at youtube http://www.youtube.com/watch?v=B9R7_SyGtWI. I have made my own pyramid with accurate measurements and i am going to use it to boost growth in my small adenium seedling.(it has a hole in the base to place the plant. and there are openings in the sides which let in light but cannot be seen in the above pic.) I hope this works because science says it will!!!!!!!!!!!!
