I have dropped my seeds in water yesterday. 29Super Silver Haze, 13White Widow and 20*Super Skunk. Planning to sprout them in Rockwool starter plugs 40mm x 36mm. Used to germinate in jiffy plugs (coco peat) want to try something different because of the high water retention the jiffy’s tend to get water locked with my RDWC system(If I leave the Jiffy’s on) and I end up with rot problems, also used to wash the jiffy soil off after my clones have rooted or my seeds have sprouted but have also been having problems with that of late(too much stress for the little ladies and too much recovery time that I cant afford).
Have taken your advice and will not be running the recirculating drippers on my DWC system!
But last night I read some pretty worrying things about Rockwool (don’t know if the post/article was more aimed at promoting GHE’s Rapid Rooters) but according to them Rockwool is the worst thing to use for germination because of its low success rate, High water retention, susceptible to mould/algae, PH problems and root rot ???
I understand how to adjust the PH and prepare the Rockwool and that Rockwool has a good water to air ratio when watered correctly but are all those negative points true?
If possible please can you give me the do’s and don’ts for Rockwool
AGAIN HOW DO I START A SUPPORT TICKET?
