Quite new to this forum business. I have been growing for maybe a total of one year with varying results. Trying organic soil this time but already thinking of going back to hydroponics. Would like to give NFT a go. Have some 2x4 size channels with 1 5/8 inch holes. Grow space is 20" x 60" x 45". Thinking Scrog using Grodand plugs. Any one with this kind of experience will to share. Another thing is that I may not be able to go with HPS lighting due to excessive heat. Where is the leading edge of LED? Is it ready comercially or still too formative. Thanks
