## Questions & Answers

**Q: What do the seeds need to grow once they are inside the pellet? Water? Sunshine? Nutrients? Nothing?**
A: You will water the pellets so that they expand to full size before you plant your seeds in them. So at first they will need nothing extra. Once they sprout and have leaves, put the mini-greenhouse in a sunny window. Water again when the pods start to dry out, but carefully remove excess. They need nothing more than this really until it is time to trans-plant the pods. The pods have what they need to start out, allowing the roots to grow out through the mesh and helping to retain a moist (not too wet/not too dry) environment. The directions on the box will tell more as well.

**Q: "
What size pellet is used for refills for the Jiffy 5710-12 Planter?**
A: Pellets are 36 mm

**Q: What are the diamentions of the tray? Also are the pellets soils okay for cactus seeds or cuttings?**
A: The tray is about 10-12" long, maybe 2-3" wide. You could do cactus seeds, but watch it carefully, to make sure they don't stay too wet. I don't see any problem with trying to grow cacti in them. Good luck.

**Q: Does this come with the peat pellets?**
A: Yes, it dose.It looks just like the picture.   Thank you

### ⭐⭐⭐⭐ Simple and Efficient
*by C***R on March 3, 2013*

I've used these seed starters for three seasons now, and it's a pretty easy task getting from seed to plant with these things. If you've never used these before, there is a plastic tray with 12 starter pods included. You add a bit of water, which expands the starters. You then peel back the netting--with a toothpick or something of comparable size--and add two or three seeds. A plastic top is then put on the container and within a few weeks, the seeds turn to plants. You then acclimate your plantings and pop the whole thing in the ground. The only problem I have with these things is that the unit is not particularly stable. The plastic is somewhat flimsy, and the plastic cover 'rests' on top, but it doesn't seal. This means you must have an out-of-the way location where wind, kids, cats, or others won't bump into them. I set mine in a large plastic tub below a window in our guest room. The other thing to keep in mind is that you want to make sure you have 'tight' rooting before you plant these. If there is not a sufficient root base (knotted and firm), the plants don't take off very well and some might even die. Anyhow, this is an efficient product for getting your seedlings started; I can't think of anything I would prefer over these.
