So I don't have to go through the entire thread and see where you're at you are flowering in 3gal fabric pots correct? Veg in 1 gal?
Need to order new pots I tossed everything from the big tent to be safe of the bugs lol
Well the pot sizes vary but for flowering I'm either in 3gal or 5gal fabrics. Veg is consistent, I go party cup to 1gal, then 3gal, then if I have time to veg a little more I'll up-pot them to 5gal about a week before flipping.
My container size for flowering is really driven by how long I've had to veg them, how long I want between watering, and keeping a good variety of strains going. A lot of rounds I'll mix 3/5gal plants thrown in a different times, staggered so I'm not having to harvest too many at the same time.
Basically the main criteria I use is how long I want/need between waterings, and some of that is driven by the time of year, and how long I've vegged. If I look at the plant size at flip time and think it'll give me at least 2 days between watering in the 3gal, I'll run it in the 3gal. If it looks a bit large for the 3gal I'll up-pot to 5gal & flip. Summer I've been running more 5gal's than 3gal's because I've been running negative DIF (lights-off temps at or higher than lights-on temps). That tends to dry the pots out quicker so the 5gal's were necessary, I was watering the 5gal's every other day and most were bone dry in that time. If I had run those plants in 3gal I would have been watering daily.
