I just pulled my jugs today, but will keep them handy for an other week or so. The plants have big fat buds on them.Ok. caps off and keep handy for a cold snap.
What are u thinking of starting under the jugs??
Lettuce, cabbage, spinnach... basically any cold weather crops. Then, for grins and giggles, I think I'll do some tomatoes, zucchini, and other squashes. You know how volunteers always come up in the spring. The milk jugs would just keep a nice little micro climate going.
