Aqueminianswered grow question 3 years ago You can defoliate if you want to, it allows for better air circulation and light penetration. Defoliation has been proven beneficial to indoor grows, it's not beneficial to outdoor grows. If your not worried about slowing growth and giving extra veg time then defoliation is always an option. If you don't want to slow growth, just slightly bend the tops out each day gently and as it get taller they will slowly grow apart. You could also tie the to something LST. Autoflowers don't get a lot of time to be trained or recover. Photoperiods can go as long as you want a d can always recover.
