Indoor DWC Amphetamine & Narcotic Kush

Wanted to try cob but it seems so new there isn't much good info. Your looks great. I'll keep watch.
 
Ok I found Mandala Seed is where I read not to use Rapid Rooters.

Go over to the Rollitup.org they have tons of info on COB Growing; it is not new and it is way more efficient than any other indoor lighting. It is not cheap to get started even if you build your own. Google Growmau5 and have a look at his "how tos" and "grows logs".

I have had a problem with this first grow with mine:
1. The seeds may have got too cold in storage as my refrigerator froze one time this past summer.
2. I had the lights turned up too high and the seedlings hit 93°F.
3. This is the first time I have used Rapid Rooters and one of the seed companies (can't remember which one) states not to use them because of a PH problem.

So I have reordered the seeds and will be restarting this grow as soon as they get here correcting all three of my suspected problems.

Stay tuned I'll get this grow done well.

Thanks gonna check that site for sure.

Ok I killed this grow today.

In an attempt to learn from my mistakes I have dissected the failed plants. Let's look at the facts:

1. both plants failed which points to environment. Some potential factors:
a. The seeds may have got too cold in storage as my refrigerator froze one time this past summer.
b. I had the lights turned up too high and the seedlings hit 93°F.
c. This is the first time I have used Rapid Rooters the Mandala seed companies states not to use them because of a PH problem.

2. the roots appear to have a type of root rot on one of them the other is simply bound in the Rapid Rooter.
a. The root rot looks a lot like nematode damage?
b. The rapid Rooters were too wet, they are too dense - air could not get in.

3. Once the tap root exited the Rapid Rooter it did not get better.
a. some type of pathogen?

So all of the above are valid potential problems and a lack of vigor due to freezing the seeds may be a leading factor in the plants not being able to exit the Rapid Rooters in time to avoid root problems.

I think the main issue is the density of the Rapid Rooters is not compatible with the DWC method I use to germinate the seeds. The RR stays too wet and air cannot get to the roots. In a soil based system I don't think this would occur. In the past I have used Park Seeds Bio-Dome sponges which are far less dense and smaller physically to germinate seeds successfully.

I have ordered the replacement seeds and will restart this grow after sanitizing my system then using the Park's Sponges I use the 60s size sponge.

16 days since germination:

Try Rockwool Bud Ive Used and Had Great Results..

Yes, rockwool performs well but it also has an inherent environmental problem that does not fit into my personal eco-minded philosophy.
Many soil growers have had excellent results with RRs but my method of bubbling moisture up from the reservoir kept them way too wet. I believe this to be the causal factor that lead to the root problems. I could be wrong because I had other potential problems.
 
Ok I cleaned and sanitized the hydro equipment. It will have a week or so to air dry while I wait the arrival of the new beans. They shipped from the U.K. yesterday.
 
I had simular probs starting direct in the cubes in the system. If you start them on paper towels and put them in the cube when they've got a nice tap root, no more probs. Jiffy pellets are good if you want to start direct in your system.

Itisi
it is isn't it?
