hm well, /wave from the lazy self-sufficient stoner's side of growing. i don't ever sell buds, and only have to grow twice a year. and, that is using a 400w lamp in a c-13, pretty basic ventilation setup and a tubbler. i could easily squeeze in 2 more grows a year without laying down any more cash, but i just don't have to.

this is not an insinuation that people here grow for profit by any means; it's part of my reasoning for just going with what's easy, and works well enough for my needs. i'm not totally disinterested in boosting my efficiency, but when i change my program to include things that are a royal pain in the ass (water changes) and don't even notice a difference, i tend to focus my attention on other things that i believe will have more of an impact.

it is my opinion that increasing my own training skills (scrogging, in this case) will greatly affect my yield, as opposed to a marginal at best improvement by becoming utter and complete master of my rez regimen. bear in mind this is dwc, i have no experience doing anything else. all i know is keep your temps below 70, your container light tight, and grow area clean in general... and it just works... for me, anyway.

as far as overferting goes, i own both a pH and tds meter, and most of the time am only adding back plain RO water... i use my pH as well as tds to determine when to administer more nutrients.

there are all sorts of reasons why what is good for the goose isn't necessarily good for the gander... not everything will work for everybody. i have found what works well enough for me, with diligent research and practical application.

frankly, this is an old argument, and on other sites have followed very successful grows by many people who do indeed abstain from the whole water change ritual. c'mon, i know there are some more lazy stoners out there... i'm certainly not alone in this.

the long and the short of it is, we all like to smoke the sweet herb, preferably without the spectre of black markets and our own governments breathing down our necks. peace.
