The Jiffy Professional Greenhouse 72 is not a full size greenhouse, but a seed starter tray with cover (was the closest category). With the cost of food skyrocketing, and having a young daughter (and wife) who love their fresh vegetables, I was interested in starting a garden. Now, granted, I dont have remotely a green thumb, but figured I grew tomatos in winter (ok, granted, yes, its florida, and we only got one, but I call that an accomplishment for a novice), so lets give it a shot. Started out with a smaller version that held 25 and started tomato seeds, within a week and a half all but one of the plants had reached the top of the container. Next paycheck we picked up this item. and started some seeds in it. Everything has sprouted and soon we'll be planting them in the garden.
The only real drawback is javing to preciously water each pellet so that it will expand but not float out of its socket. Also, if you overwater you run the risk of some mold sprouting. We had a small problem with this in the tomatos. The other issue is that fully planted the tray has a tendency to bend the middle. I almost dumped it a number of times moving it right after it was planted. All in all, this seems to be a pretty effective seed starter for its low price.
