Assume you mean on the grodan twins m8??
Ive been watering just as I feel they need although been reading lots and think I need to be feeding once per day at least.. im using tap water just and EC still 1.0.. I've got a better idea after even 12 days with these 2 so I've put another seed in cubes to germ for a more thought out effort. I honestly wasn't even sure these first couple would make through the first few days so was a bit sort of guess as u go with them haha
Do u water every day from day 1?? If you have any tips advice instructions or recommendations for these wee cubes at all im all ears bro.. more than happy to take advice from someone who can wreck it in grodan like you
