So it is reccomended to keep the seedlings in the cups for three to four weeks? Also, that is the amount of time I am supposed to keep them in the seedling soil? I read it caused trama to the seedlings to transplant them into a new type of different soil. The MG seedling soil has much less nutrients obviously then the MG 3 month time release self feeding soil. I would actually prefer to use the beer pong cups cause I already have a healthy stock from a recent visit to Sams club. I just thought the dixie cups were bigger. I can see how the material of the red cups would stand up better to the water. Also, I can get some of those quart containers made for plants if that would be more healthy. Thanks to everyone that answered me as it is greatly appreciated. :weedpoke:
