Another question that has occurred to me is the fundamental difference between a CF and EC meter. They both seem to measure the ionic content in the water.

I am all for that. Any advice you can offer would be greatly appreciated. The first go-around was pretty abysmal.

The first plants have already been harvested. Those are the ones that produced so little that I was prompted to create this thread, just to get some feedback on what could potentially have been the problem(s). There are a few plants almost ready to pull. I will get some pictures of those.

Another thing that I have read about and am trying to get an answer to is the issue of being able to accurately assess the relative levels of the different nutrients. I have seen listed the existence of a measuring device called a CF meter which measures conductivity and scales that to a...

The fact that you adjust the pH when you add nutrients actually brings up another issue that I will be dealing with very shortly. I have placed an order and have seeds on the way, so I will be beginning germination possibly within a week or so. I have read multiple postings on several...

i have read that pet experts recommend allowing water to sit out for a day or so, to allow the dispersal of chlorine, before putting it down for watering. I figured that the same would probably hold true with plants but I had just recently read about this issue and wanted to get some opinions. I...

I do have a pH tester, but the resources I had read talked about the presence specifically of chlorine and fluoride being detrimental, despite the pH value. That was why I was expressing concern.

I have seen on other sites the warning to not use tap water, because of the chlorine and fluoride additives. Is there a general consensus on this? If that is true, is distilled water the best option? If so, what is the best source for that? If a grower had to purchase gallons and gallons of...

Do you know if this publication is available on-line, or would a person have to buy a hard copy?

The biggest problem I am experiencing, at this point, is that almost all of this is brand new to me, so I am overwhelmed with information. Since many of these postings are a random mish-mash of different topics, it is difficult for me to coordinate all of this into a linear format that I can...

We are using both high-pressure sodium and metal halide. I know that the wattage on at least one of those types is 400 watts, possibly on both. We have about fifty seeds that have already germinated in small pots that we are placing out on shelves tomorrow, with fluorescent lighting. I just...

I am a first-time grower. I produced a few plants that were of very good quality, but the yield was extremely low. I was able to harvest only between 1/8 and ¼ oz. per plant. I am preparing to start a new batch consisting of a few dozen plants but I hate to have identical results. These plants...
