hey caddy,
The water farm is super, but the design has a few flaws that you should address before beginning. Look up "water farm mods" on google. In my system, roots from one of the plants clogged up the holes between the top and bottom buckets, almost causing the top bucket to overflow. Consequently, most water farm users drill bigger holes in the bottom of each of the top buckets to allow more drainage to occur. I wish I had known about this mod before I started, as drilling holes in a pot with a four foot plant growing out of the top and shifting around is not fun.
Also, I would strongly suggest implementing a cutoff valve between the reservoir and controller unit. I neglected to do this from the onset, and as a result had to remove the reservoir in the middle of my grow.
The problem is if your system isn't completely full, there's no way to PH adjust the nutrient solution before allowing it into your controller. I ended up just adding nutrients directly to the controller and adjusting from there.
Using dual cutoff valves in between the individual "pods" will allow for maintenance-related removal of any of the system components. In my current system, this is impossible, and consequently, If I had a major failure in the back of my system, I would be screwed. Next grow: Definitely implementing this!!!
Also, most water farmers use an air stone in each of the bottom buckets. This oxygenates the water, and prevents root rot in the seeker roots that hang down into the bottom buckets. With both mods in place, I use a 24/7 feeding schedule. Because there's so much O2 in betweenthe hydroton, the roots in the top bucket are fine with being watered 24/7. With the airstone in the bottom bucket, the roots that make their way into the bottom are fine as well.
Algae: oooh algae. This one almost cost me a crop. Algae sucks!!!! Fortunately, it's pretty easy to stop. Basically, you have two options:
Option A: you can completely deny it any light. This is commonly accomplished by placing coco mats over the nutrient rings with a large enough hole to fit the stem through. If this is done at the same time you plant your plants, You're going to want to leave at least a 1" hole in the mat to allow for stem expansion, depending on the size of your grow.
Option B: is to use an algaecidal agent of some sort. I went with this option, as there was no way I could place coco that far back. I used BioCat, and it killed the algae dead in one or two days.
Hope this helps man!

delicious looking strain there. I am starting my 1st hydro grow, I bought the water farm and was wondering what kind of timing schedule you use...I've read different things but obviously your doing great, also how did you combat the algae?
