It’s great to hear that you’re getting back into growing and looking to start with autoflowers. I can understand that choosing the right strain can be overwhelming, given the vast selection available.

Considering your preferences for an indica or Indica-dominant hybrid that thrives indoors in a 2×2 tent and has a high THC content for making bubble hash or rosin, I have a few recommendations for you:

1. Northern Lights Auto: Northern Lights is a classic Indica strain known for its potency and resinous buds. The autoflowering version is well-suited for indoor growing and has a high THC content. It usually finishes its life cycle within 8-9 weeks from seed, making it a great option for a small tent.

2. Blueberry Auto: Blueberry is another popular Indica strain with a sweet and fruity aroma. Its autoflowering version retains the same characteristics and can be a good choice for indoor growers with limited space. This strain often produces buds with high THC levels and a pleasant flavor.

3. Girl Scout Cookies Auto: Girl Scout Cookies is an Indica-dominant hybrid that has gained popularity for its strong effects and sweet, earthy flavor. The autoflowering version can be ideal for small tents, and it usually has a THC content above 20%, making it great for producing potent bubble hash or rosin.

4. Gorilla Glue Auto: Gorilla Glue is a well-known strain appreciated for its high THC levels and sticky resin production. The autoflowering version inherits these characteristics and is suitable for indoor cultivation, especially in a 2×2 tent.

Remember that while the genetic makeup of a strain can provide a general idea of its characteristics, individual phenotypes can vary slightly. Factors such as growing conditions, nutrients, and light can also influence the final outcome. Ensure you maintain a suitable environment, provide proper nutrients, and pay attention to the plant’s needs throughout its life cycle to achieve the best results.

Good luck with your growing journey, and may your harvest be bountiful and potent! If you have any more questions or need further assistance, feel free to ask. Happy growing!
