If you are leaving in an environment that is too hot or too cold, try the following techniques to help control temperature around the plants:
Too Cold:
1 . Place the plants on top of the fridge or beside an electric device that generates heat.
2. Heating mats- an affordable solution to maintaining the soil at the ideal
temperature during the colder months, and designed specifically for seed starting.
You simply place your pot on the mat, and set the mat to the desired temperature
(80°F).
There are some great options for Heating Mats on Amazon. Only buy a product
with an MET Safety Certification! The price range should be between $10–$30 US.
3. You can use grow lights, which are great for both providing enough light to your
plants, and can keep the soil temperature at the desired levels.
There are some great options for grow lights on Amazon. If you do buy grow
lights, there is no need to spend more than $25 US.
When choosing grow lights, it is recommended to pick a product with 3-5 dimming
levels, and with flexible timer options.
Grow Lights provide Blue Light and Red Light which are used in different stages
of the growth period. If you decide to purchase, we recommend you adequately
research how to optimise the effect of your grow lights.
4. Create a mini greenhouse from clear plastic drink bottles. Simply cut the bottle in half using sharp scissors, then place the top half over your plant. Keep the lid off on sunny days, and place it back on when cold weather is forecasted.
A similar effect can be achieved by placing clear foil over the plant on cold days. Be sure not to leave it on for too long, as without ventilation, mold will form.
