Thundercat thanks to you all for looking in and keeping the tread going I appreciate it.
iloveit, my favourite grow method is probably top feed or flood & drain they are both simple to run and set up and both give very good yields.
I dry at a relative humidity of approx 62 and temps of approx 72, the stems should crack rather than bend when fully dry, the buds also need to feel dry to the touch but obviously not too dry that they crumble to dust, a humidity of 62 helps prevent this.
The Wilma system is very good, if you are using clay pebbles I would recommend using the high flow drippers that come with it (the blue ones) as the higher flow rate gives better results. If you place a small pump in the res it helps to increase the dissolved oxygen (DO) and keeps things mixed up nicely, and I have my res temps at around 19C.
trapper, the flow into the system is controlled by using a bypass in the res, on the pipe which comes from the output side of the pump I have a "T" fitted. One side of the T feeds the system the other has a valve fitted (doesnt matter what type) if I open the valve some of the water from the pump goes back to the res so I have full control over how much flow enters the system.
If you look at this picture you can see the pump at the bottom right, then there is a "T" look to the left and you can see the valve with a green circle, in the picture the valve is half way open, so the pump is recirculating some of the liquid directly back to the res. If I fully open the valve the flow to the vertical is reduced simply because more of the water is recirculated. If I close the valve no water is recirculated and the full output of the pump is sent to the vert. (I hope the picture explains it better than I did! lol).
Hi
whitenugz, The system is only fully cleaned at the end of each harvest, throughout the grow I simply empty the res once a week and refill with fresh nutrient solution. Because the system runs with flooded tubes the nutrient is a partial change because I dont drain the tubes. At the end of the grow I simply pull out the roots which is very easy as they come out intact and then swill it out with a hosepipe.
A rule of thumb I use on my grows is to run the flow fast enough to exchange the water at least 5 times per hour. In the vertical the water is flowing through at a rate of at least 2000 litres per hour, the faster the flow rate the more DO you will have. Have a look at my answer to Trapper about how the flow rate is controlled hopefully that will answer it for you.
The water runs 24/7, it has to as it is the only means of providing the necessary DO.
bobhope1925, Yes thats a good way of doing it, I have an Aeroflo system which works in the same way and it works perfectly. I also looked at the nft spiral and built a small section to test it and again it worked fine. The only thing you have to do is put a small tail of spreader mat or something hanging out of the bottom of the net pot to allow water to wick up to the plant until the roots are long enough to reach down to the water flow.
merahoon, the only thing I have changed this time round is I have put in larger cuttings, other than that the system seems to be working very well. So any modifications I do will be minor.
vicbudz, the netpots are 3".
Hey
bigbuddc, I climb into the vertical where the pipes step down to the next level, this is easy to do when the system is empty and the plants are small but not easy at the end! In the pic you can see the low part where I climb in.
Ha Ha cheers
OldRookie, good to see you here!.
No update today as I forgot my camera! but everything is running fine, I will try put some new pics up on thurs or fri
