Q.Do I Need To Use A Heater For A Small Home-made Greenhouse To Start Vegatable Seeds In Early April In South Jersey?

Zone 08110 | joecornely added on March 20, 2021 | Answered

This is my 3rd year gardening. I have 1400 sq feet. Half for tomatoes and half divided between peppers, cucumbers, zucchini, and green beans The first two years I purchased starter plants but want to try my hand at seeds. I looked at indoor with a grow lamp and outdoor with a homemade greenhouse (shelves enclosed with clear plastic) I prefer outdoor. Should I put a heating pad or if that is not enough, a small electric heater inside the enclosure for night time? I live in NJ across from Phila. How cold can seedlings take?

Make sure to follow the instruction listed on the seed packs, as each seedling will have a different set of tolerances. When you go by the instructions, it will not be necessary to take any special precautions. However, if you are planting outside of the parameters listed for each species, then it will need help to keep it within its parameters.
