Are you asking "Is 500 watts of CFL's enough to supply 25 sq. ft. of growing area with light?"? Then the answer is Hell no!.

Yes.

Because they are just weak, little, wimpy, baby-assed leaves! Give them a few days to buff-up!

It's purely a matter of "How much Light - vs. - how much Space". If you've got 10,000 lumens lighting up a 1 sq. ft. footprint - then yes - that's probably excessive! If you've got a 2 sq. ft. footprint - that's just about the right amount of light for that area. If you've got 3 sq. ft. or...

Soiless medium considered hydro or soil? Whether a medium is considered to be hydro or soil isn't a matter of if it contains actual soil or not. It's a matter of how much nutrients all of the soilmix ingredients contain collectively. If the medium is relatively nutrient free, it is considered...

Yep! It's called "Guppy Ponics", Google it.

I hear the dispensaries are charging $5. , $10. , $15. , even $20. a gram (depending on quality). That is rediculous, since they are supposed to be Non-Profit organizations. I've never actually crunched the numbers and done the math myself - but I'll bet some of you have! So, here's the...

How many plants have you grown under 1 x 300 watt LED? I don't mean to sound "Preachy" - but - - -. This is a public service announcement for all Newbies (and anybody else who doesn't get what's wrong with the "How many plants" questions). Your lights don't know (or care) how many plants are...

There was a time (many moons ago) when I used "Chemical Nutes". Way back when, before it was called "Jack's Classic", it was owned by a different company (Peters) and it was called "Peters All-Purpose, 20-20-20". This had to be 20 or more years ago, about the time I found the Internet. I...

If everything else is "OK", the only thing that comes to mind is a bad pH situation. Have you checked the pH? Those yellow leaves indicate that they are not getting the required nutrients. If you're feeding the right stuff (but they're not really getting it) - I would suspect nute lock-out...

Well, for one thing, the problem is that (your friend) is using Halogen lights.

Yes there are, but you probably won't find them at a grow shop. There are all kinds of weird color temperatures! They are made for people with salt water aquariums, to grow coral.

Call it what you want, but those photos don't look like Indica to me - they look like Sativa. Just sayin'.

Can you get away with only drying 3 days and cure 1 week? Of course you can. If you're the only one smoking it! Will it smell and taste like crap? Of course it will! Anyone can just throw some shit together and eat it, in the blink of an eye - no matter how bad it tastes, it's still food...

He means "Ultra Violet" - it is actually "UV-B". It's what you get in those "Reptile Lights" that they sell at Petco.

Okay. okay - I take it all back! I did a little extra digging and this link - http://www.pmodwrc.ch/newrad2005/pdfabstracts/Newrad044.pdf - is what I came up with. Appearantly the scientific community does indeed recocognize a "Modified" version of The Inverse Square Law (as it applies to...

I would say it's more like impossibly complicated. If your premis is even correct (I've never heard of this before - how would you even begin to calculate the amount your light source is spreading out?). If you're saying what I think you're saying - you would need an almost infinite amount...

It really cracks my up when I hear people talk about "The Inverse Square Law" - some of them really don't understand it, but they go on and quote it anyway. 2Hearts comes very close to explaining it in post #66. The Inverse Square Law is only applicable to "Point Light Sources". A Point...

Bump!

The color of the pistols is irrelevant - go by the color of the trichomes.
