Hi Stupid :) Now, I don't know squat about growing Caladiums, but 2,500 foot-candles seems a lot. Aren't they shade plants? I would think these would be happy in 1,000 foot-candles. I'm guessing 10" pots? That would make about ten square feet you need to light and you really need about 15,000 lumens. Boost up all my numbers if they need more light or you have bigger pots. Normally you would be looking for efficiency and long life, but in your case you should just find the cheapest fluorescent bulbs that you can and add them up to about 200W. All that changes if you plan on using the bulbs every year or to grow other stuff, then you'd want a more efficient system that cost more up front. So you'll probably end up with a bunch of cool white 40W T12 tubes from Home Depot and the cheapest shop lights you can find. Efficiency and long life in this case would probably be a 250W metal halide lamp costing several hundred dollars. For seedlings you can stick the tubes right on the top of the seedlings and get really intense light, but that doesn't work with big plants because the top gets fried and the bottom doesn't get enough light. You need you tubes maybe 6"-12" from the top of the leaves and you need to rig a reflector around the tubes to send all the light down onto the plants. You can buy them, but maybe you should just bend some aluminium sheet into a half-circle, or use mylar, or whatever you can lay your hands on. A totally different approach would be to rig a temporary heated greenhouse affair outside. Sunlight is free and it seems like all you would have to do is keep it warm for a couple of months.

many times it is not the actual site that is bad but one of the ads that was on the site that was bad many ads are corrupt and carry infections, if it is detected on a site then it has to red line that site as a warning. Yes it has many times happened that the owners and friends of bad sites will all gang up on wot and give rave reviews trying to get rid of the red warning. I personally always write why I give a site a specific rating not everyone does so just because you do not see anything written does not mean those that are there were the only ones. More people do not leave a reason why than those that do unfortunately. Those of us in the security forums always try to red wot any site we know of that has any type of security issues, especially drive by infections which are often in an ad and could be there today and gone tomorrow. but if it was there that does not speak real highly of the website construction and code and their scrutiny of what is going on their site. all things to keep in mind. When I am on my windows machines if I get a red wot I do not enter period.

LOL! Yep same thing happened to me. My husband (my GC) had just connected my new kitchen light switches a little different then I was used to. That evening, I started cooking dinner. It was getting dark, so I tried the switch. Nothing happens. I say to myself...Hmmm, that's weird. Something must have tripped the breaker. Tried them again.... Yes I really did flip em all on, off, on, off....like that was going to work! Now understand, I had been living in construction zone for like a year at that point. I think, oh well DH will be home any minute. I will just wait for him to deal with it. Hubby gets home, walks in, and just as I was about to say...hey something is wrong with the electrical, he flips the switches. Boom, all the lights come on. Yeah, I felt pretty stupid.... I forgot I had him switch the kitchen and living room switches. Duh! We laughed pretty hard on that one! :-D

Thank you, floral_uk. I appreciate your response. I've only watered the shrubs once or twice this year, they've definitely not been over-watered. If anything, they've been under-watered. The dirt around this shrub was dry as a bone, way down, so I watered it heavily today. I have sandy, rocky soil, and I've been told by my neighbor who grows trees that our soil is impossible to over water. Besides, my other 8 Lilacs look spectacular, and this one did too til I messed it up with my stupidity. :( I'm going to give this Lilac all of this year to show me it can survive. It's the least I can do for this poor victim of near involuntary shrub-slaughter.
