Well you can take them if you are only a week or so into flower, but after that you would have to reset the entire plant as far as I can tell. The process goes: When you harvest don't cut the entire plant. Just do your individual branches and colas and leave as many fan leaves as you can and put the cycle back to 18/6 and after a couple of weeks you will notice the vegetative growth start back up and the plant will get more shoots. However you can only rejuvenate once. Now I can't be 100% sure but it seems that the stress of going into flower and back out a couple of times increases the risk of having your plant turn into a hermaphrodite.
I can barely believe I am moving into it so quickly too! After I graduate nursing school in December I am going to be moving into my own apartment so.... Gotta lighten the load and make sure I have enough to get me through the move... They are always so stresful, but I have a feeling that this time the process will be much more enjoyable!
Hey, Goblin! First off I'm glad you stopped by! That book is a real gem and if you were thinking about getting it, I recommend that you do! It is like the WalMart of growbooks. It has a lot of useful stuff and the pictures are great! However, there are a lot of particulars that could have been expanded on and I recommend you supplement this book with any good Marijuana Grow Bible you can download. You have the pictures so the odd bits and pieces you hear about in the MGB you can see what they are in the Buds For Less. You get more information on fertilizers and cloning in the MGB also. BFL just uses Miracle Grow extended feed soil (most growers here are passionately anti-Miracle Grow so you can see why it is good to have both. And you can download the MGB for free in many places!
Now, I did have some food and culinary herb growing experience and this is an acclaimed beginner's strain, but you are right! This is not 1/8th as difficult as I thought it was going to be from some of the posts. It is totally just a weed and while it has some likes and dislikes it can grow just about anywhere whether or not you want it to. Light water and dirt is really all you need! The rest of the fiddling is just to increase the yields and make growing easier. Hell, my grow is ghetto as all get out! I have lights hanging from neckties and 'repurposed' wire hangers, but it all works fine. The thing that I have seen with a lot of people's grows to make them fail is their fear that they are doing something wrong. They over fertilize cuz they want the biggest yields and so much more. The next biggest problem seems to be impatience. The most complicated thing witha CFL grow is the light positioning and that is just a little bit extra time babying your plants...
As for the seeds. I got my seeds from Nirvana Seeds. They are from the Netherlands, but the service record is immaculate and the delivery speed was unbelievable! I got my seeds in just at 2 weeks and the packaging was so discreet that I thought I got scammed until I took a closer look! LOL I am in the Deep South so your delivery time my be a hair longer.
