It depends on the variety, the rootstock (if they are grafted) and your soil. Grafted J&P roses didn't do very well for me, my soil doesn't like roses grafted on Dr. Huey. On the other hand, the J&P New generation roses that are own root but their size and roots were enormous did extremely well. Most of these New generation roses were David Austins and they reached their listed full height or close to it in the first year. Black Magic from J&P grafted on fortuniana should be huge and bushy and it is a skinny and weak plant (in its second year) compared to Crown Princess Margareta or Christopher Marlowe, both own roots. Jubilee celebration, a supposedly (and hopefully) small, low growing Austin also performed very well in its first year. I doubt that I will ever purchase grafted J&P roses again but I am and will be tempted by their own root roses. Of you list I have only DD from J&P, must be 8 or 9 years plant, the only 'milk carton' I ever purchased. It did well in its first year, it was the first to bloom; it was a grafted plant but 2 years later we dug up and replanted with the bud union deeper so it went own root. It did better own root in my yard though after 8 years its performance has become disappointing. But, YMMV since you garden a different zone and maybe your soil will also have a lot to do with the performance of the J&P roses.

My wife and I went through a Haworthia phase, but it didn't last since most of our nice pots got rained on by all the junky trees we had overhead and over time half the plants rotted out... I still have a few hundred plants, but I can't for the life of me identify even half of them anymore. Here are a few of the pots that did and didn't work This pot was a wife creation and had several nice plants in it... but we have this Acacia baileyana tree in the yard that rains tons of sticky pollen a gazillion little leaves. We really needed to get some shade cloth for these plants. This pot has something else in it now. Tried to keep this pot in sun room, but despite two sky lites and lots of windows, all plants got severely etiolated and then ... well, you know Nice pot my wife put together... actually did well for a seveal years, but in an area under shade cloth and again, too little light after a while this pot did great for 3 years and then several of the Haworthias just over grew all the others... still have it, but it only has 3 huge plants in it now Still have this pot, but is has suffered from raining leaves and sap as well here it is 4 years later this pot was one of the best... wife's creation... sadly the wood rotted and then so did the plants (or many of them.. a lot of them are now planted about the yard and doing well). can't find the early photos of this pot... was a triple decker thing and had some relatively common, cheaper Haworthias.. and now they live in a shadier area (things grow in the yard) and are super green and sort of leggy due to low light.. .but it's still there another creation we no longer have (no clue where this one went) this is one of two razor rock pots and these are extremely well draining pots.. both still exist 4 years later and the plants are still pretty healthy... this one now is in a tad too much sun and this one is in too much shade, but the plants in it are doing well, probably because such good drainage This pot is our best creation (wife's again)... still looks great to this day and it is in the perfect spot in the yard where gets a lot of light, but no direct sun light and no icky pollen or leaves from overhead trees. I didn't upload a photo of the other side, but it is nice as well

I have only CFL bulbs - am not saying they are the best, but they are very good. Main reason I am using them is that I got about 55 (!) brand new bulbs few yrs ago (most of them were given to me free). So I started using them and since they last long time, I am still using them. They were all 23W, and I purchased few more (higher wattage - equi to 150W incandescent). I have many plants and they are on wire shelves, so lights are easy to be suspended from the shelves. In my case, I use 'vanity strips' as bulb holders + some I made from sockets that are easy to buy. The reflectors you are looking at are very often recommended and I think they will work very well in your situation - they could be clamped on so easy to adjust for any position of plants. I am in similar climate/zone as you, and winter days without supplemental lights are too dark - and I do not have GH! :) These have worked very well for me, and I will probably buy some T5HO tubes in the future - but that is likely years away, before most of my bulbs give up. And by then, there may be LED's available for much less $ (and hopefully, I'll learn more about them!). We are still having really nice weather - actually heat wave that started almost at the beginning of September. Temps are way too high (for us - high 80-ties and even over 90*F) and suppose to stay that way for few more days. Looks like beginning of October will be more seasonal but still nice enough to keep plants outside... I would recommend to read - this thread - there are posts by ppl using T5HO (for example ewwmayo and some others) and LEDs - Oksana in Siberia uses only LEDs to grow her jades.

It being a succulent it's hard to believe you couldn't get the upper part to root and make a new plant. Meanwhile the cause of the problem is probably inadequate light.
