The isolated seeds that are offered here have been grown under nets or inside bags. I will never put a seed n the isolated section unless I have grown it myself and confirmed it was pollinated while netted. While this does not guarantee 100% that it will not be a cross, the odds are greatly increased compared to the open pollinated selection. One thing this method will not help with is stability. Many of the seeds being offered are new hybrids, particularly in the Super Hot collections. I try to note in the description when a seed is a hybrid or cross and that future grows from that seed may show variations.
