I have spent the last few weeks slowly putting this room together from the ground up. With my limited height I chose to do a low profile nft/dwc system. My total height from the top of the PVC pipe to my maximum height before the light burns them is 40inches. Each plant will have 1ft^2 space. I have 4 seven foot long PVC pipes with seven 2.5" holes along each for a total of 28 plant sites. Right now I'm forced to use a 1000w MH but will eventually get 2 600w hps. My total growing area is 7'x4' so I'm hoping I've got enough light. I currently have Sour Diesel, Super Lemon Haze, Purple Haze, and Brand X. I will eventually do one strain at a time and do the SOG method. This isn't my first hydro set up but it is the biggest. My clones I have started today using a little Clonex when I made the cut and when I got home I threw them in my bubble cloner. This is my first grow journal and will be making updates when I can.I would love any tips or feedback. I have the pipes on a slope and water with Hesi nutes will be pumped into the highest one, flow through the entire system and back into the plastic tote. I am a little worried that the plants at the end of the pipes may not get the same amount of nutes the other plants get. If I have the entire thing level, about an inch of water is in the pipes. When I put the slope on it the water is very shallow. I'll have to play with the slope a bit and see what the plants like better. I will put some pics up in a day or so. Everything is set until I get some roots.
The plants at the end of your system will get the same amount of nutrients as the plants at the start. The concentration will be equal, but the water level may not. I don't have the best idea of what your system looks like, so I could give you better feedback once you get some pics. Anyways, this thread should be redirected to "Grow Journals-Hydroponics." Hopefully a moderator can direct you to the correct destination.
