Likely story. Your "slip" was clearly a subconscious manifestation of your deep seated conviction that I'm wilfully depriving myself of the pleasures of the diode.
I never posted "old florescent bulbs being incapable of supporting plants ", I posted about loss of PAR. I believe you did understand my meaning as you posted " don't measure PAR and I don't worry about the spectrum " Twisting the meaning of my posts is weak and beneath you.
No. No, NO
I can't cope with invalid arguments (we all have our cross to bear).
- You said a 5 year old bulb will not provide “the Par needed to grow plants.”
- If a bulb does not provide enough X to grow plants, then that bulb is unable to grow plants.
- “Unable to support plants” (what I said) is just another way of saying “unable to grow plants.”
Don't make me post the laws of logical entailment, man, 'cause I'll do it.
There is a major difference between Survive and Thrive. Unless you can produce some independent test data you don't have an "empirical fact" you have biased personal opinion.
Oh come on - tell me it’s not glaringly obvious whether a plant is merely “surviving” vs. “thriving.” I bet you a bucephalandra you could tell from across the room with both hands tied behind your back.
2. Fine, empirical this: two days ago I had to trim 6"-8" off my Hygro. A month before that I had to trim to 6"-8" off my Hygro. Two months before that I had to trim 6"-8" off my Hygro. And so on for as long as I’ve been growing the stuff - 6"-8" needs to come off every month.
What I can believe happened is you had way more light (PAR) levels that you needed in the beginning, it's degraded over the years as ALL florescent tubes do, and now you left with enough to keep the plants alive.
Could be, if by "alive" you mean "continue to thrive" (but this wouldn’t change the fact that your statement about my old bulb being unable to grow plants is simply wrong (just thought I’d point that out
But since even my current old bulb causes my Ludwigia’s leaves to go very red as it approaches the surface; if a new bulb really supplies dramatically more energy wouldn’t you expect the near-surface leaves to burn to a crisp every time I put a new bulb in?
