First pic is a pepper that was grown in my cold 59F house. The second is a pepper that was taken to my 70-80F office building for about a month or so. Both sown and sprouted at the same time. Half my peppers stayed home, other half in office. These are average examples of each. 7 varieties of pepper, ~30 plants total.
Home plant had decent grow light, was fed half strength fish emulsion multiple times, and in the past few weeks has been spending days outside with real sun (when temps are above 59F). Office plant was never fed and had sun through a window a few hours a day, no grow light.
They are two different varieties but the difference is clear. Grow tents for me next time! Keep that heat in!
