I have several difficult to set heaters, but they do not ask for actual temperature.
We are looking for questions about gardening rather than equipment. We have a policy not to recommend product names. You might try calling a company that sells greenhouse heaters and asking questions or try searching the Internet for answers.
When should I be setting this up and is there anything in particular I should do.
You can set this up at any time! Here are some articles to help: https://www.gardeningknowhow.com/garden-how-to/projects/building-cold-frames.htm

My 14 x 14 greenhouse in SE Alaska has shelves 4' above floor and vegetables suffer from radiation -floor plants are ok. What do I need for shade? Also, currants are ripening on bush and robins will eat soon. what do you recommend?
This extension fact sheet explains the variables to consider when purchasing shade cloth. For veggies, 20 to 40 percent is ideal.

I just built a double hoop house( 2 layers of plastic) with a 1"-3" gap. My questions are: 1) How can I water my plants in the middle of a deep freeze (is it safe)? 2) I want to heat my hoop house with either a 2'-6' Ice melting mat between 2 raised beds (64 sq ft) covered with round stones to act as a radiant heat system and / or using a overhead infrared heater. I live in zone 6B. My hoop house will get full morning sun up until around 3:00 PM in winter. Thank You

I am turkish. I am sorry, if I have a mistake in my question because I don't know the English a lot of. I use sulfur in the greenhouse for pH of soil. Does sulfur emit harmful chemicals into the air if I add sulfur to the soil?
Be sure to follow the instructions on the package label before applying sulfer to the soil. Sulfer, however, is low in toxicity to people. There are other ways to add sulfer to the soil if you are worried about it. Here is more:
