  1. I have got a NFT system. It is looks like exactly the GT100 just a bit smaller. It is 90 cm x 90 cm, or 3 'x 3'. It has the same res, tray, feeder bar. I bought an adjustable pump too. I read several topics but i didn't find answers for my questions. 1. Is the spreader mat some kind of geotextil? I have this on a large roll (i think it is 1.5 m x 100 m roll and maybe 1-2 mm thick and white). I assume it is good (it's not chemically treated), isn't it? 2. I read that the mat is good to drop to the res because it eliminates the dripping water sound ( i will use air stones in the res). But how much? Below water line is fine? In this case the mat not will be too wet due the capillary action? 3. I really really hate rockwool. I tried it several times but always failed (salt build up, Ph problems and overwatering). I found an alternative which called easy plug and easy block. The plug is 3,5 cm x 3,5 cm x 3 cm and the block is 7,5 cm x 7,5 cm x 6 cm. It has been made of organic materials like root riot, rapid rooter. It has an 1.0 EC and a steady PH of 6.0. But it's bottom is flat. Can i use this in NFT? I can't see why not the NFT instruction says i can put a well rooted coco or even soil plant onto it. What do you mean? 4. I am very afraid of overwatering on the NFT tray. Should i put something below the cube? Just to raise a bit from the mat. I read several opinion about water pump running time also. Run constantly but adjust the flow. Run on timer. Even one post said in the beginning not use the pump the plant get some moisture due the capillary action of the mat (if it is in the res). Can you give me some solid advice? I don't want to fail just in the beginning
