I’ve spent many $$ and and killed a few plants using rockwool/mesh cups in 3.5gall food grade buckets. pH around 6.8. Temp high with lights on 84-86 w/exhaust fan running when lights are on, 78 when off. Humidity range from 50-60. Input fan runs 24/7 and oscillating fan 4-5 hrs/day. I add 2t...

fyi - White vinegar lowers the pH in my 7.0-7.5 r/o water

I can't grow dead seeds

By "sprout" I mean breaking the surface once planted. So what would you call a plant that breaks the surface?

Nah, turns out all my 4-8 year old seeds are dead (what a waste). Invested in quality genetics and so far am 5 for 5 in germination. Very happy!

I have many rock wool cubes and am setup for DWC. So far I have 5 of 5 seeds germinated, 3 sprouted. I was impatient when 2 of the 3 seeds didn't sprout after 4-5 days so I germinated 2 more (mistake) and am waiting for them to sprout as well. I use rockwool/mesh cups so I can just move them to...

How long after the seed sprouts do you start adding the barley solution?

I took advice and invested in 3 strains, soaked in r/o water and all 3 grew tails.

Hello again ya'all! After trying almost everything under the sun to germinate my seeds, I've determined the seeds are dead (what a waste). I took advice and invested in 3 strains, soaked in r/o water and all 3 grew tails. All 3 are "planted" in rockwool/mesh. One has sprouted and sits happily on...

Weekly update: After changing untreated r/o water (pH of 7) after a 20 hour soak most all of 13 seeds sank, but none split or grew tails. I am determined to get at least a few to sprout using materials I've already purchased, rock/mesh or potting soil, preferably rock wool. One "seed site" said...

Hello everybody! I still haven't had any seeds split using pH balanced r/o water. The napkin/baggie method just grow white fuzz and gets moldy(?). I put a rock wool mesh cup on the window sill, nothing. I started the potting soil method, 2-3 seeds per cup in an egg carton (closed) on top of...

Ok gang, I promised an update and here it is. It's been 9 days. I've had seeds on a 2 hour soak also a 24 hour soak in r/o water with a pH of 7-7.5, in a damp napkin inside a ziploc. I keep them in the microwave as its dark, warm(?) and less air as suggested. I have very recently neutralized...

I am soooo happy I joined this forum! I'm sure I'll have many more questions as my success evolves with all your help! I've already started a 2 hour soak and a 12-18 hour soak in R/O water. Lights and fans are now off....room temp 76-80 and 55-60% humidity are pretty constant. Ziplocks and damp...

Any info is appreciated at this point thank you!

Info was provided to identify what I am doing. Obviously I dont have a clue! I will also try this method and hope for the best. Thanks for the input!

Thanks for the response! I was afraid I was drowning them. I'll take them off the "veg" light and try this. I stored them in airtight glucose test strip container in a dark area. My guess is they're 3-4 years old. If/when they sprout they sprout, how long before putting them in rockwool?

I read your post on 3% H2O2 3ml/500 ml solution for 12 hours...I'm gonna try it today! Can I re-use seeds already in rockwool or start over w/new (old) seeds?

Brand new to DWC, and yes I've done a ton of research. Over the years I've saved seeds but can't get them to germinate in a rockwool/ mesh net setting. Using 1000w LED full spectrum, non oscillating fan, charcoal filter w/195 cfm fan, air intake is in planning stage. I'm using R/O water no nutes...
