Hey buddy nice set up. I'm a fellow hydro head. Anything you need to know just tag me and I'll get back when I'm on
Couple things jumping out at me.
Firstly, keep the plant in just the rockwool for a few days till its rooted up.
Personally I go 2 weeks but just whenever there's a few roots poking through is good enough.
Reason being. You want the cubes like 30-40% wet. Too wet and the roots will drown, too dry and theyll fry. Keep it there and the roots will grow infinitely faster. They also just need water at this point. My taps run 48ppm and they can go on that for 6 days. Easiest way with best root development is in a humidity box of some sort. Mines cost 99p.
I seen you say you soaked them in ph water, did you rinse the shit out of em first? Gotta give em a good long rinse under slowish running water (so they dont fall apart) to get all the crap out. It's alkaline as fuck and stunts them if your unlucky. Last thing you need with autos.
Secondly that's a big tent. I'm too stoned to go hunting the lights down, I'll get sidetracked and go off on a tangent somewhere. ..
but you're probably a bit shy depending on what the green finger one is. Also cheap shit chinese blurples are alright. I use them amongst other things.
Really shit ones are brilliant for seedlings cos you can get em closer. Don't chuck it.
And lastly are you using sm90, hydroguard or something like that to keep the res clean? Some manage without it but it's really risky. Usually ends in root rot and masses of gunge.
I go for sm90. Only need 0.3ml/L so it goes pretty far like. Handy to use as a root booster for seedlings too
Hey thanks dude. I did not rinse the Rockwool after soaking (fuck) after reading your post I seemed to have fucked up quite a bit. I’ve just been using uc roots from current culture (is that enough) also I just chucked them straight in rock wool after they geeked and then straight into the system with water about an inch below rock wool. I kinda knew my ppm was way out of line but I was following a chart from current culture and only added small amount day 6 (ppm around 440) and did this because they seemed like they weren’t growing hahaha which I’ve read a thousand times not to do but for some reason did it anyway. I’m day 13 today. Flushed the system last night and added way to much nutrients again (ppm 980)so came home from work not long ago and dialed it back to 870 but it’s jumping around at the moment so hopefully it settles in a bit. Ill be adding more lights later as needed. I have a shit ton of those shitty Chinese blur pals if I need to bust me out. Just never heard good things. I’ll throw up some photos and you can let me know if I’m killing these poor girls hahaha very much appreciated mate!!!!!
not sure what it is.real nice set up and the others look fine
