hi
i love auto flower and did a grow outside before the weather turned
1 buckets are a bad choice ..........
here order some of these ...........small yeild plants can go in 3 gallon bag larger yeild plants need 5 gallons to 7 gallons (becuase of the water rentention amount larger plants need more water) ...........these are fabric bags the roots air prune so no balling up and dying out / since fabric they breath so water can not pool up flushing them is simple and if it rains it will only hold so much the rest of the water flows out
2nd thing 12/12 is only for flowering u want auto flowering plants on a 20/4 this will get as much growth as u can before u move to natural sunlight .........auto flowers are time based growth after a certin period of time they hit a lvl and then flower if u have gotten reduced growth in this time then your yeilds will be lower becuase of it but they will be thicker tigher buds due to increase amount of goodies for smaller flowering yeild
3rd the soil in the bags make sure it is good and set up for weed i say fox farm ocean forest (just fill bags and plant )
4 ..........soils need a organic feed .......look up GO BOX on amazon it is a all in one buy/kit for growing a few plants like 12 .........has a feed plan on the side and it is a complete line in one buy
5.........order some 1 ml and 3 ml pipettes u have a few plants going i say 500 count of each (they are used to mix the feed into 1 gallon of water)
oh and for next grow
get some jiffyplugs and the spourting tray use it (top of the frig old tv something warm) normally 3 to 4 days they are ready then move the plug strait into the bag the plant is going to grow in for life
transplanting them is not the best idea start them off and put in final bag let them go u will get better results
