Well it would seem that my recent run of good luck in the grow room has run out. Earlier I was checking in on the coco plants when I noticed some orange colouring on the strings that I'm using to tie down the branches. upon closer inspection I can see that it is a type of mould which reminds me of the orange slime mould I had last year in my barneys journal. I dont think that it is the same though but I have had to untie all of the plants as you can see the mould climbing the string. I thought that I had it figured out as the fabric pots have been through the washing machine at 90C so they are clean however the string was brought in from outside. The mould starts on the string around the fabric loops so I assumed that the wicking was causing that part of the string to become wet and create an environment for whatever was living on the string to thrive in. You can see it on all of the strings, starting in exactly the same place and beginning to creep up towards the branches. It doesnt appear to be on any of the fabric loops which dont have string attached. My theory seemed sound until I opened up the veg tent and saw exactly the same thing but there is no string in here at all.
I have been doing a lot of reading about mould (again) this afternoon and have decided that it probably isn't a threat to the plants though mould spores aren't a great thing especially if they are in your bedroom. Also I wasn't going to take the chance with the mould coming into direct contact with the plants via the strings so I think removing them was a good idea. Initially I thought that it must be because of the bottom feeding with the water being almost constantly in the tray but I dont think that it is. I found a lot of examples of this kind of mould being on fabric pots that were being watered the normal way. I found examples of it on coco and soil to. Many people said that it isn't like Botrytis and stays on habitable medium which happens to be wet medium. If this was a soil grow then I would allow the pots to dry before waterings which is what is happening in the 100w tent. No problems in there of any sort in regards to mould. With coco though the medium should stay wet constantly.
Here's what I have done and will do in the future. As I've already said first I removed the contaminated strings and threw them on the compost. That mould is still useful believe it or not lol. I then gave the fabric loops a little spray with some ISO solution to combat the visible threat on the pots. I dont know if it will work but I'm sure that it wont cause any harm to try. Today's watering had some H2O2 mixed in as a preventative. I'll incorporate some into the watering's from now on. I'm using 10ml per litre. something I'm considering is transplanting the mothers out of the fabric pots and putting them back into plastic. Mould doesnt like plastic as much as the fabric pots which can get pretty scummy after a little while. There is not much I can do about the flowering plants but for the next round I could use plastic again and see if bottom feeding works as well without the wicking ability of the fabric pots.
I have given the plants another good trim to increase the airflow lower in the tent. The humidity is still good and is well below the danger zone. It has been at around 55% for much of the day and I know that it is about 65% throughout the night. There is also good air movement in the tent which is a bit annoying but seeing mould is a sign that something is not quite right. Anyway here is a pic of some mould that you can't quite see as well with the camera as you can with the naked eye....
And this is what I did to my plants....
I didn't go mental and showed some out of character restraint.....
So there you have it. I sleep in a mouldy bedroom. Maybe it came from Sauga's rice cake....
