Am considering growing in a shed . Given fluctuations all year around am trying to work with led summer and perhaps hps winter. Wondering if I can work around the options . I have a shed 7x7 x7. Would love to run led all around. Thinking of tent 4x4 x7 high. Can I get away running led all year. Are there options for increasing temps in my shed. I was thinking of just allowing the minimal exhaust to flow around. Though perhaps the led would not be sufficient during cold winters . Wondering how to offset during cold temps. . I am prepared for the best options and no budget. Need to led really, given current expense. .Also are there AC units that members could advise during critical times. Am thinking small portable. TIA.
