If the buyer followed ILGM’s germination guide and the seeds didn’t sprout, the brand will send replacements of the same strain free of charge.

  • Special deals for bulk orders


  • Doesn’t offer a germination guarantee

Seeds Offered

Deals and Discounts

One of the best California cannabis seed banks currently holds two BOGO sales, including “Buy 5 Get 5” and “Buy 10 Get 10”. The only drawback is that each customer can only benefit from these sales on two seed packs. Even without all the discounts, Sunwest Genetics seeds are highly affordable.

Germinating Guarantee

Sunwest Genetics offers a germination guarantee. The brand’s spokesperson said each seed is handpicked and tested for quality. However, this guarantee does not mention free replacements for failed seeds.

Shipping & Refunds 

This seed bank ships to all U.S. states (and internationally); free shipping is available on all orders over $200, while purchases exceeding $420 are also eligible for free seed packs.

Deals and Discounts

Sonoma Seeds offers its customers a 10% discount on all orders via newsletter subscription, which works with ongoing BOGO 25 deals. Its prices are on the low end, to begin with, so even without all these deals, Sonoma is a great place to buy marijuana seeds on a budget.

The brand currently holds BOGO sales on 5 and 10-seed packs, offering excellent value for the money on products like Auto CBD Green Maverick, Cherry Punch, Pie Gal, Grease Gun, and many others.

Germinating Guarantee

Beaver Seeds does not explicitly offer a germination guarantee, but none of the reviews ever noted that this was a problem for the brand’s customers. Returning buyers imparted that virtually all seeds purchased from this brand successfully germinated.

Shipping & Refunds 

Shipping options Beaver Seeds offers are identical to the ones provided by Sunwest Genetics and Sonoma Seeds. Regular shipping may take up to a week, while priority shipping costs an extra $20; orders of $200+ are eligible for free shipping.

Refunds are rarely given since only orders without tracking numbers are eligible for a money-back, and this is why Beaver Seeds is not placed higher on our list of the best California seed banks.


Beaver Seeds has been in the marijuana seeds business since 2009, so it shouldn’t be surprising that their catalog of THC seeds is more significant relative to many younger brands. Its deals are quite lucrative, but what makes it truly stand out is its collection of ultra-potent THC strains.

Whether you’re after a hard-hitting Indica, a cerebral Sativa, or a balanced hybrid, the strain selection can make all the difference.

Growing Cannabis from Seeds at California Seed Banks: A Beginner’s Guide

Cultivating cannabis from seeds can be an enriching experience, offering an intimate connection with the plant and the satisfaction of nurturing it from seed to harvest.

This guide will walk you through the essential stages of growing cannabis from seeds you can purchase from the best seed banks in California, providing essential knowledge for beginners and refreshing the memory of seasoned growers.

Germination: Starting from Seed

After finalizing your purchase from any of the California seed banks we discussed here, germination is the first step in your cannabis-growing journey.

This is when the life of your cannabis plant begins, as the seed cracks open and a small white root emerges. You can use several methods to germinate your seeds, such as the paper towel method or planting directly into a growing medium.

Providing the right conditions – moisture, warmth, and darkness – is crucial for successful germination. Remember, patience is critical during this stage, as germination can take anywhere from 24 hours to a week, and many California seed banks offer germination guarantees.

Seedling Care: Nurturing Young Plants

After germination, your seeds will grow into tiny seedlings. This stage requires careful attention as seedlings are fragile and prone to damage. Ensure they receive plenty of light, but avoid direct sunlight as it can cause harm, and this is true no matter which seeds from which California seed banks you get.

Keep the growing medium moist but not waterlogged to prevent overwatering. Also, it’s essential to maintain a warm temperature, as seedlings prefer a slightly warmer environment than mature plants.

With proper care, your seedlings will develop their first set of true leaves, indicating readiness to move to the vegetative stage.

Vegetative Stage: Building a Strong Foundation

The vegetative stage is where your cannabis plant will do most of its growing. This stage focuses on developing a strong and healthy plant with lots of green foliage.

This means providing ample light (up to 18 hours daily) and regular watering and feeding.

The more robust the growth during this stage, the better the foundation for flowering and yield. It’s also the time to start training your plants, if you wish, using techniques like topping or low-stress training to maximize light exposure and promote more bud sites.

Flowering Stage: Maximizing Yield and Potency

The flowering stage is when your cannabis plant starts producing buds. This is the most exciting phase for many growers as you’ll begin to see the fruits of your labor. To initiate flowering, you’ll need to adjust the light cycle to 12 hours of light and 12 hours of darkness.

This mimics the natural change in daylight hours as the seasons transition from summer to fall, signaling to the plant that it’s time to reproduce. Proper nutrients, particularly phosphorus and potassium, support bud development during this stage.

Regular monitoring is crucial to catch any potential issues early, such as pests or nutrient deficiencies.

Harvesting and Curing: The Final Steps

Harvesting and curing are the final steps of growing cannabis strains. Knowing when to harvest requires careful observation. Look for signs like the pistils changing color and the trichomes becoming milky white with a hint of amber. Once harvested, the buds need to be dried and cured properly.

Drying involves hanging the buds in a dark, cool, and well-ventilated area. The curing process, which consists of storing the buds in airtight jars and opening them periodically, helps enhance the flavor and potency of your cannabis.

These final steps require patience but are crucial for a high-quality end product. But for a good start, make sure you get your seeds from the best California seed banks, and you cannot go wrong.
