BrokenBow's Indoor Grow

If they're going to finish at different times you should also consider where you will dry the plants that finish first; your plants aren't huge but if they double or more in size before harvest I think you have your tent pretty much full as is. All the other points you thought of are also valid - but I suppose if you have the other 2 plants and no where else to put them you can always cross those problems as they arise. Worse case ontario you have to move them elsewhere in a few weeks.
