Buring a solo cup takes up the top few inches of a pot, and the roots are then forced out the bottom only. You are trapping a large portion of top roots from growing out ward upon transplant. You are also watering backwards. Watering by the stem is counter productive. You are putting a barrier between the outside of your pot, where you should actually be watering. The outer edge of the pot should be more moist than near the stem when top watering. Forcing the roots to reach for the outer edges of the pot, horizontally. You are forcing the roots vertically only vs horizontally and verically when you water the cup first.Not doubting your experience for a second! I just wanna learn. Like I said, all your opinions matter to me.
I understand about roots needing horizontal space. What I don’t understand is, does it really need a horizontal space larger than the solo cup for its first 10 days or so? If this is the case, wouldn’t all seedling containers be a foot wide? How different is this from someone transplanting a seedling from a 500ml container? With the cup, I get to maintain moisture easier and it wicks into the soil, making overwatering unlikely. It also directs the roots towards the soil below where there is more moisture. The cup dries out faster than soil under it, driving roots downwards and then expands in all directions. Isn’t that what we want? Sounds exactly like what you mentioned too? So why is it bad again?
Why wouldn’t the top part of cup have the same root system as a transplanted seedling? Before transplant, the seedling has the exact amount of room as the one buried. In fact, there is risk of transplanting too late but when you bury it, there isnt.
In hydro, a similar process with net pots but actually makes the plant stronger? With cups showing a bit from soil, I can even see exactly how moist it is.
If you want to start a plant directly in the final pot it is easy, and the best for Autos if possible to do it. You just make a hole the size of your Solo cup, fill that wiith starter soil and plant directly. Water around the outside of the pot, and just keep the starter soil slightly moist. But you have to keep the final pot warmer to have optimal results. If your environment is only 75f, dont start directly. Shoot for 80-85f. Here is a goid way to think of it if you are top watering a trsnsplanted seedling. Dont water the roots diirectly, water away from them. When you pour water down thst cup, you are watering the roots directly. This gives them little motivation to grow fast and seek moisture...because you soaked them directly. Ideally we want the roots to grow horizontally and vertically at about the same rate. So if you top water around the outer edge, the roots grow both Horizontslly and vertically...and sre not soaking the roots directly during the transplant phase. Use your medium like a sponge, wicking from outside in. Sip Containers work really well because it is even moisture and not direct contact with the seedlings root system. Good luck, slow
