Good advice footclan!!!
Well I have been growing since christ was a cowboy and I wish someone told me to go organic right from the get go. I started with ebb and flow 4x8 rock wool bla bla bla than bubble buckets, than thin film and thousands of dollars later and 1000's of hours adjusting this and that what a drag. I have grown in dirt, in raised beds 4x4 and 4x8 I just water never flush, I can't anyhow but don't need to. I don't even dig the beds up I just pull the old plant out and put in the new one. It has made my life so simple, just water every 5 to 8 days.
Great products to use coco, worm castings THIS is GOLD, get some.
My source for nutrients are; composted cow, composted sea, worm castings, blood & bone meal that's it. I top dress every 4 months and water in.
I use 1000w and my yield has increased by 30% and I will put my girls up against any hydro any time.
The best way to increase your yield is to get it down to a science, monitor everything, temp, humility, co2 and measure everything, find a great seed and stick to it and learn what it likes and does not.
Tell no one!!! And don't flap your lips when you hear people talking about growing. Security!!
Some things you will hear a lot about on this forum is Molasses, I use it and do recommend it at a rate of 1/2 tbs or 7ml per gallon. There is no current research to support all the anecdotal evidence. The other is Tea's ACCT or not. Again there is no proof but I use them when I feel like I should fiddle with my grow.
All the best
