Accidental re-vegging happens when a cannabis plant has started the flowering stage and then reverts back to the vegetative stage. This happens because photoperiod strains require long, uninterrupted nights of darkness to produce buds. This is why indoor growers usually give their plants at least 12 hours of uninterrupted darkness each day when switching to the flowering stage.
Accidental re-vegging can happen if light leaks into your grow tent and interrupts your plants much-needed darkness. Even a small amount of light can interrupt your plant’s beauty sleep and throw it back into a vegetative state.
When this happens, you have two choices:
- let your plants completely revegetate if you wanted to be back in the vegetative state, or
- correct the light periods and remove any possible leaks of light to give your plants 12 hours of uninterrupted darkness each day.
A plant that has just started to flower can accidentally re-veg quicker than a plant that has been in the flowering stage for a month or more. The longer the plant has been flowering, the longer it will take to reverse the re-vegging. Do not panic if this happens to your precious plants, simply decide what stage you want your plant to be in an act accordingly.
