Using cactus mix for seed starting is an interesting idea, but it has its own set of challenges. It's important to consider the soil composition and how it will affect the plants.

Promix HP (High Porosity) is a popular choice for seedlings as it is very dry. Watering every day with just a teaspoon or two works well. However, when potting the seedlings into Promix, they need less water than before.

It turns out that pure sand can also be used for seed starting. An old Connecticut Ag Experiment Station study found success in this method. Just bear in mind that more frequent fertilizing may be necessary because sand does not hold onto fertilizer well.

Though cactus mix could work, it might be better to stick with standard seed starting or potting mixes and figure out the over-watering issue. Top-watering instead of bottom-watering could help reduce moisture levels. Even if the surface looks dry, it doesn't always mean it needs watering, particularly if you're bottom-watering.

Gardening has come a long way since 1972, when Burpee's Pixie was first grown from seed using Jiffy Mix and Gro-Lux WS bulbs on a 4-shelf plant stand. Despite 50 years of practice, gardeners still face challenges sometimes due to bad habits creeping in.For example, over-watering is a common problem. It's easy to do when you're starting out and don't know any better. But it can lead to root rot, which will kill the seedlings before they have a chance to grow into healthy plants.

To avoid this issue with cactus mix or other soil types, use self-watering containers that allow excess water to drain away from the roots of your seedlings. This way you won't be tempted to overwater them as much because there's no need for frequent watering in these systems.

Also consider using an organic fertilizer like fish emulsion or seaweed extract instead of chemical fertilizers if possible; these are gentler on young plants and help promote strong root growth without burning them up too quickly with high levels of nitrogen or phosphorus found in some synthetic fertilizers.

Finally, make sure your potting mix has good drainage so that water doesn’t stay around the roots for too long after each watering session - this could cause problems such as fungal diseases down the line if not addressed properly!

Overall, while cactus mix may work well for certain applications (such as succulents), it might not be ideal for all kinds of seeds due its unique composition and lack of nutrients compared to standard potting mixes available today - but experimentation never hurts!

What is the usual suspects for starting tomato seeds?

The usual suspects for starting tomato seeds are standard seed starting or potting mixes.

What is the problem with over-watering?

The problem with over-watering is that the mix is dry at the surface, but still wet on the bottom. This can cause the plants to suffer when they are about a month old.

Is it possible to start seedlings in cactus mix?

It is possible to start seedlings in cactus mix, which is a sandy mix with a little peat and perlite in it. Adding a small amount of Tomato Tone dry fertilizer may also be beneficial.

What other soil mix can be used for seedlings?

Promix HP (High Porosity) can be used for all seedlings. It is very dry, so it should be watered every day using a teaspoon or two.

Is it possible to start seedlings even in pure sand?

It is possible to start seedlings even in pure sand, according to an old Connecticut Ag Experiment Station study. However, more frequent fertilization may be necessary as sand does not hold onto fertilizer well.

How can I avoid over-watering issues?

To avoid over-watering issues, switch to top-watering instead of bottom-watering, or water less often. A dry soil surface doesn't necessarily mean it's time to water.

What was the experience of an experienced gardener?

An experienced gardener found that when they first started gardening, they had zero problems with their seedlings. They used Jiffy Mix and built a 4-shelf plant stand with 4 foot shop lights using Gro-Lux WS bulbs.

Are there any tips for successful seedling growth?

Tips for successful seedling growth include using standard seed starting or potting mixes, top-watering instead of bottom-watering, and watering less often. Additionally, adding a small amount of Tomato Tone dry fertilizer may be beneficial.
