Hi Lucian,
Yes, I also use this setup for sowing. You are right about the temperature. I always place the pots so the temperature is around 30C. At night time I place the pots in my greenhouse where the temperature is 10C... The shift in temperature from day to night is also a good way to get higher germination.

Great work Dan they are all going to be very nice plants.
I particularly like the last one(cause the seed came from me Ha ha!). And it shows characteristics I was aiming for with the crossings, dark colour(from scaph and confusus(purple form)) and wooly groove from pect plus the boat shaped tubercles of scaph.
But jokes aside all of them are  really awesome work mate!

Thank you Simon (:
I have several grafts from that cross, and they all seem to develop very strong pectinatus stripes. I'm quite exited to see how they develop as they get larger.

hello Dan, wonderful view!
Do you make all the grafts before winter or do you do them during wintertime too?
Because we grafted on peresk but since peresk grow very fast under lights and they are all water seedlings do not attach as well as in summer. Any advices about it? Do you put the grafts under the lights when you just have done them or later?

thanks

Hi C+D,
Thanks alot. Many of the plants came from your seeds (:
I always graft in late september / early october, so I take the pereskiopsis direct from the greenhouse, and graft on them. After the graft is made, they are left in normal daylight in the aquarium (no electric light and no direct sunlight) for 14-18 days. After that they go under the lights for the entire winter. The seedlings don't see any real sunlight before they are around 6 months old.
I have never grafted on pereskiopsis in the wintertime.
Have you tried to keep the pereskiopsis dry for 3-4 days before grafting? that usually give better attachment to the stock if you have problems with floating seedlings.

hello Dan and thanks!
Yes we dried the peresk for 3-4 days before graft, but once we put the seedling on it the peresk continues to bring liquids to the top.
We never had this problem during summer, but in winter they grow very fast and it's a bit more difficult to graft on them.

At first my grafts would always end up with a weak/thin connection because the vascular pressure would just push the scion. The way I got over this issue is using a cling wrap method to keep the high humidity and constant pressure on the join resulting in constant results. I have a much higher success rate and don't need to place the pereskiopsis into a high humidity chamber. There is also no need to 'dry' the pereskiopsis a few days before as the pressure of the wrap prevents the scion from moving and getting pushed off. However this method does take a little longer than just placing on top and with the large amount of grafts you guys perform may take longer.

Here is a youtube video depicting the method
