ahh sweet man. yeah im sound, just had to get some metal slag scraped out my eye. great fun lol.
have you ever looked into NFT? if your not doing r/dwc then id have a look mate. exact same method but as far as i can tell its a much more efficient system for a single plant grow. multiple plants do not have the same results at all. go check out KushNFT latest grow. he took a 22 day break from posting at around day 14 and his plants, each in a single plant system, grew as much as 4 ft !!!! and he uses the ionic line wich is about as cheap and simple as it gets with hydro. unbelievalble results! taught me most of what i know : ) ive only ever found 4 people that use them (gt205) and ive no idea why. you dont even need an air pump. i put a 2w airstone in my current one but only because i could. she'd survive without it. went on a bender and left the full room off for nearly 2 days in late veg and didnt hurt her in the slightest. wicked system and only costs £35 including all the extras of recirating water pump, spreader mat to ensure equal distribution of the water flow, corex cover. all you need is gro cubes, sticky, tape and a power supply
