Hello everyone! I've been a full time gardener for around 8-9 years now & I feel like I grow nice produce...once it's in the ground! Now on my 4th or 5th of having a greenhouse but I feel like my greenhouse growing skills are subpar at the most. I use new or disinfected pots/trays, use professional growing mediums, use warm water, water when plants look like they need it or when trays are light, use compost tea to fertilize after 3 weeks, good circulation, but my plants are always pretty sad looking :(. The only thing I can think of that is my problem is the temperature extremes; ~40-100. What do you think? Thank you
