with auto flowering plants your not talking about growing 'trees' or bushes, time is limited so you want the appropriate size vessel to support the plant, 2-5 gallon will easily support the quick growing autos and I'm sure you can fit a dozen of them under a 400W footprint. If they overgrow the space then I'll be a monkey's uncle. So there.
Shovelhandle Reviewed by Shovelhandle on . Any advice for my first grow? I'm currently planning for my first grow in the next week or so. I ordered an 400 watt dimmable grow tent set. My tent is 60x60x78. Is this tent too big for a 400 watt light? I am planning to grow six auto plants. I got a northern light variety. Is 6 plants too much for my 400 watt light? Could I do more than six? I have read that these plants tend to be smaller and do not require very strong light to thrive. I am gonna do a 16 an 8 light cycle. Any feedback would be appreciated.
