Good news and bad news. First the good news.
4 of the 6 treated cuttings and 1 of the 6 non-treated cuttings have several roots between 1/2″ and 1″ long. I’ve separated them out into their own pots. I did notice a couple of the non treated cuttings had what looked like bumps that will soon be roots. There is a lot of new growth and I’ve already had to pick off blooms.
Now for the bad news. I believe there is a fungus among us. The leaves started turning a bit dark and wilting on some of the cuttings, mostly the older leaves.. It happened almost overnight. I mixed up a peroxide/water spray and treated them. Not sure if it will make a difference or not. I should have opened up the plastic covers earlier. Some of the leaves got so big they were up against the plastic and stayed pretty wet due to the condensation. I knew better than to let that happen but ended up getting busy and forgetting I wanted to do something about it. The next time I try this I am going to use 2 liter soda bottles with the bottom cut off to keep the humidity up. I can leave the cap off and get more air flow.
I had ended up swapping out the 40 watt bulb for a 60 watt bulb in the rooting chamber. I was able to keep the soil at a pretty constant 72 F throughout.
I found a currant/gooseberry diagnostic page. Very informative.
It appears that the cuttings will be fine. Removing the plastic from the rooted cuttings seems to have done the trick. They are already showing some new growth that is devoid of the darkening.
