Hello guys! I am planning to switch from soil to NFT. But there are still some questions before I can start with that. My NFT-System will be a Nutriculture Multi DUCT MD802 or MD804. I am also planning on having following strains: Channel+ Power Plant Ultra Power Plant Northern Lights Ed Rosenthal Superbud Bubba Kush 2.0 My questions are: - Will this variety of strains be a problem, since I only have one watertank for all those strains available? Are those strains suitable for NFT? - Would you recommend buying cutlings in rockwool with 1,5x1,5 or 3x3 inches? Or isn't there any benefit besides the 3x3 were some days longer in vegetation? - How often do you think will I have to adjust PH and EC? I am thinking of buying an automatic feeding system because I can't be there every day. -If I buy a bigger tank, I won't have to adjust the PH/EC as often as with a smaller one, right? Cheers!
