Covering net cups

[Joker]

I'm on my 5th dwc grow. I have had fairly successful grows until the last one and I got root rot despite using hydrogard. I was wondering if any of you cover your net cups to keep light out? This time I video tested for light leaks before I added water and some light was filtering thru the slits in the net cups. This time I covered them so that just a small area around stem is open but it looks like I'm starting to get RR again. Very frustrated! I used new totes, new water pumps and hose, basically everything that contacts the water or roots is new. Any thoughts?

I take some black white polly, cut it to the shape of your totes and just cut a small hole for the stem. Are you using hydroton in your net cups?

 

[Joker]

Yea I use hydroton in the cups.

Howdy Joker, If in doubt, cover it up!

I always cover mine up and if pails are white then I do the same with the panda film and have the white on the outside for light reflection. You can cut a circle for the top the same size as the pot and slit to the center then fold and made cuts so it ends up looking like a pie cut into pieces at the center to allow for the stem growth to go through.

I put duct tape over the net pot to cover it light sucks below ya buds.

Joker, what changed from the successful grows to the root rot? What's your water temp?

 

[Joker]

Thanks everyone!

 

[Joker]

Thats the thing...I'm just not sure what may have changed. The last grow I used the totes pumps etc from the previous grow, I just sanitized them. I thought this time I wouldn't have any problem😖

I will post pics of the roots tomorrow, hopefully it's nothing but me being paranoid 😉

Temps in the mid to high 60's

Every once in a while I have a bout of root rot from light now I just use duct tape. I got a sure fire plan to get rid of it now. I also have switch from hydrogard loved it. To slf 100. Love it more. Now days tho I go the first 3 weeks useing an aeroponic set up in my dwc bucket and that really makes them young roots grow. I have spent alot of time working on my root growth. I grow autos so roots are everything to me.

 

[Joker]

I will look into that slf100, thanks!

Joker With those temps, I would conclude that it has to be a light leak. At least, that was my experience. I had to get on the floor on my back and lift my reservoir lid to discover the leaks when I had to deal with root rot.

 

[Joker]

Looks like the one has it for sure and the other may be starting

Just ordered some slf100, thanks for the tip.
