What’s Your Grower Experience?
It goes without saying, but if you’re a novice grower, you want easy-to-grow autoflower marijuana seeds.
Lucky you, most of the autoflower weed seeds we’ve selected don’t need much care. Still, there are some that demand more attention in terms of trimming and protecting against diseases.
To make sure you punch within your cultivator weight, check seed descriptions to determine the growth difficulty first.
Where Do You Want To Grow Them?
First off, Indica strains generally grow short and bushy plants, so they work great when grown indoors.
Conversely, Sativa autoflowering plants grow quite tall and hence might need more outdoor grow room.
Other than that; plant odor could also affect your privacy as a grower.
Indica-dominant plants give a pungent air, and if grown outside could attract some glances.
On the flip side, Sativa plants have spicy and sweet aromas, so they can be grown outside without reeking much.
Weigh the THC to CBD Content
Again, high THC cannabis strains are associated with marijuana’s recreational highs.
On the other hand, high CBD strains might not give active highs but have more potential healing properties.
So, before you pick a strain, think about the effect you want and go for the appropriate strain.
