I dont even know but I thought it was cool

Not sure if this is really helpful or whatever but I thought it was pretty nifty. I have a few more plants going outside this year. I kinda held off on putting them outside so its a little of a late start for me. Most of my plants were outside about 1 1/2 months ago. Anyways. I have about 10 or so getting ready. 8 of them are on a little table under the light in my hydro veg room. I also have a 3 gtallon bucket with a lid ,DWC, with three holes cute in it for a cloner. Two of the clones rooted and were taken out of the cloner leaving two holes in the top of the lid. So since it was late and I didnt have anything to cover the open holes at the moment I placed two of the pots, one on each hole. So a few days go by and I see that those two plants are doing alot better then the ones on the little table. So lastnight Im looking and wondering why those two are bigger and look just better then the others. I pick one of the pots up and I got my answer. The roots grew out of the pots on is now hanging into to res. Like I said I dont know if this can be used for anything I just thought it was neat.

The first pic is of the ones on the table and the last three are of the two on the lid.

Cant really tell the difference in the pics though I guess.
