surreptitious,
Amen to who cares what the variety really is so long as they give good yield and good smokes!
It looks like your coming along pretty good. Good luck and remember these plants grew wild nearly all over the world for eons without fancy nutrients, PHed water, HID lights, so if you are careful not to go to extremes, the most you will do is to cut down the yield or the high, maybe both.
Pepper and Mindzeye are both correct and both wrong. There is a place for seat of the pants growing and trial and error BUT there is also a place for using "crutches/aids" like meters special nutrients and the experiences of others. Personally I'm too old to learn enough to not need the crutches. I doubt if I'll live long enough to walk without them and I know I'll never cease to seek the benefits of other's experiences. However, I do NOT advocate blindly following any one's advice if it doesn't make sense to me.
I'm a firm believer in listening to the scientists so long as it makes sense. I also seek the advice of the manufacturer of the products I choose to use as a starting point. After all they are there to both make a good product but to sell them too. If they just kick their prices up and tell you the wrong way to use them, then they soon start loosing customers to companies that make less expensive products and tell you the correct way to use them. I have some very experienced friends that have nearly identical operations, grow from the same cloned grandmothers but us different nute lines. One spends in the neighborhood of $1000 per cycle (I believe he is using AN), another one spending around $500 per cycle (I think he uses either Bonticare or GH) and another spending around $50 per cycle using FHD nutrients. All threeare growing 10 plants per cycle, and on the average they all get within 10% of the same yield and I can't tell you who grew the stuff when I smoke it unless I already know. Now I have no complaint on how someone wants to spend their money, BUT I'm sure as heck going to try the FDH before the other more expensive lines. I also have made it a practice to to contact the manufacturer directly and ask them directly, which of your products are necessary and which ones make the biggest difference for the dollar spent. I also ask questions like how does the media effect your advice. Right now I'm uisng only FHD's 3 part basic nutrients until I get more money and can start using other of their products and I'm amazed the difference it has made in my plants being grown side by side from the same mothers in both our scratch dirt and black gold. I am about to stat into WaterFarm hydro and wil guarantee you that I will start with the FHD until I get a lot more picky about my weed and a lot more money available. I'm convinced from watching the various forums and my personal acquaintances that YOUR TECHNIQUE IS A LOT MORE IMPORTANT THAN YOUR CHOICE OF NUTRIENTS, YOUR CHOICE OF LIGHT, OR YOUR CHOICE OF MANY DIFFERENT ITEMS THAT GO INTO THE OPERATIONS! I have known people who get absolutely out standing yields with killer smoke in the most primitive operations with the most far fetched sounding nutrients and techniques and others that have the cutting edge of every thing including the most "in" nutrients that can't get half of the yield that the primitive grower gets and their weed is less than half as good as the primitive guys. It seems like the difference is the degree of loving care that the plants are given, but I've seen some growers just scatter seeds in moist sub-irrigate areas, walk away from it and come back when they theink it is harvest time, chop them down, dry them and smoke them and have good yields with killer smoke.
Don't be afraid to ask questions, read the forums regularly to get a feel for the different posters and THINK about every thing you read before you try it and you will do great. There is more knowledge on these forums than any one person can ever learn. Personally I tend to be more acepting of thow e posters who aren't always insisting that their way is the best or only way.
Good smoking and remember it is hard to get bad smoke, it is just some is better than others.
a nice rich green.
