Any experience with 4 in block on hydroton?

Quick question. Experience prefered but hypothesis gladly welcomed.

If I were to put a 4 in block with a well vegged plant with the roots showing into a one gallon pot filled with hydroton and coax it like it was a rapid rooter then when the flod waters only hit those roots and not the block and the block got dry but the roots stayed wet would the plant live?

I mean the roots would flourish. Well, if it was a rapid rooter or small rockwool bloch they would but when that 4 in block stops getting wet would this kill the plant? Would the 4 in block dry out? If it did not hit the water at all and was beyond the wicking point would this be ok?

I was dreaming about running 4 in blocks to veg until the roots showed. Then placing the blocks into one gallon pots with hydroton and taking them into some more veg till the roots grew a little then flower. I was thinking I would then have almost 2 gallon pots. I have now some rockwool four in blocks on another 4 in block and i was thinking why not hydroton.

any thought or experience? I know there are a few growers who place four in blocks into dwc and they keep the 4 in block dry while the roots grow into the hydroton of their netpot lids and into the dwc waters.

I am thinking that this might work. I was looking at a 2 block system I have right now for an experiment. One 4 on anther and I have been letting it dry out a little and so far with the top block getting dry the growth continues. IDK, this is only a week or two of observation which means nothing. I am not trying to reinvent the wheel here I was just wondering if that top block getting dry would kill the roots in it or they would live. I am betting htey would live.

thru hours of scanning I found this https://www.rollitup.org/grow-journals/265993-riu-you-chose-im-growing.html. Here is a current grow doing what I am thinking about. I plant to try to start the cubes higher or to raise them progressively as I go. The 4 in cubes can hold a lot but the root grow out of the block fast. I had one in a five inch turbgarden pot a long time ago with a three week veg I got an ounce. I used 4 in blocks with loos rw mini cubes to make up the diference. I used GH, like I am now. Only diference is that time I grew 12 from seed and had 1 female! On a 3x3 table. This time I got some better economy planned. I am also thinking about using one gallon pots of rubber chips (like hydroton) and then transplanting to 8-10 in netpot lids and five gallon buckets with a dripper and retunr lines heading back to the res. Maybe use a 600 watt bare bulb for four plants and try vert. Anyway. I am having fun, like I might have said I got a surplus of equipment laying around. Tables, turbgardens, reservours, and fivegallon buckets. I am however stuck vegging out the proper clone donators. So I got time! I can recomed the rubber chips. SO easy to use and reuse and no cleaning really but disenfecting with some h202. Flood like hydroton, once every 2 hours got me good growth every time in veg.
