The bottom of the access tube is just sticking below the net pot, but not too far below to impede access to the nute solution. See how the tubing is protected by the drip ring in front. Drilled a 1/4' hole behind the drip ring in order to allow a clear vinyl tube access to the bottom of the bucket. I have just tested this and it works beautifully. Now I can take a turkey baster and pull out some nutes to test em and using a funnel, pour solution and anything else I need back into the waterfarm without picking it up. What I did was make an access tube to the resevoir. This was so I could put an 8.5' long piece of 1.5' PVC pipe through the water farm. Notice the big ass hole drilled in the corner? The reason I did this was in the standard waterfarm bottom, when filled with a root mass, the water has a doesn't efficiently enough draining back into the resevoir. I drilled out a bunch of holes the same size as the ones that were already drilled in, then I took a smaller drill bit and drilled in between all the bigger holes. So, here's what I did to solve these problems and I think that this does a fantastic job of fixing the only real pains of using stand alone waterfarms. I think that with the lack of drainage and the lack of adequate aeration, the solution might not have been kept at peak efficiency. And the holes in the bottom of the waterfarm didn't allow for enough drainage when the plant was mature as the rootball used most of the holes to grow into the resevoir. It dripped, but had to work on it and if the reserve got low at all, as it did daily later on in bloom, it didn't really pump very well at all. The third and fourth minor issues I had was the pump that comes with the complete module is only a 1.5L per hour pump. Wasn't such a big deal until later in the bloom phase when the plant was friggin gigantic. I also had to pick up the top half to add more nute water later on in the grow as the plant was a thirsty little lady. Had to pick up the top a little and sit it caddy corner on the top rim while I took readings and then balanced the nute solution. I had to check the ph every day and balance it as it would swing from about 6.2 when balanced to 7.0 every day. Then it was a big heavy pain in the ass.Дў. This wasn't soo bad until late in bloom when I had a big f-ing root ball to deal with and a four and a half foot plant stickin out the top. I then had to transfer the upper half back to the filled unit. I changed my nutes every week according to the GH feeding schedule and in order to do that I had to pick up the first half of the farm and place it into another lower unit while I drained out the old and refilled with the new. Anyways, after I completed that grow, which netted me with a little over 2 oz of sweet Mex dro I took a closer look at my waterfarm to see if I could solve a couple of issues that I was having. You can look under my profile to see my very first post as I was having bloom problems.No blooming due to light leaks.

My first grow I used a GH Waterfarm being told that it was simple, adequately efficient and that it works.

Better with mods well bucket
