It is best to eliminate the bugs before starting seedlings or new clones as they cannot stand the chemicals in most incecticides. Smaller plants root structures are not fully developed and small at the early stages, not to mention have just gone through shock during the transplant (if clone).

If I were you when finished with this crop, spray the whole grow chamber down with a strong incecticide, and then wash every nook and cranny with bleach. Then use a soap incecticide such as 'EndAll' as a prevention spray. Spray afdter the forst month of growth and then continue every 2 weeks until the crop is finished. The last 4 weeks of budding you can stop using it as it is better for the smoker. Hope this helps and good luck!
