Outdoor 35 Gallon Grow Kit – Expansion Kit

Price range: $259.95 through $1,240.00

Description

The 35 Gallon Large Outdoor Expansion Grow Kit is the ultimate setup for cultivating massive, tree-sized cannabis plants right in your backyard garden, greenhouse, or open patio. The box is heavy because the living soil volume is massive. Frankly, scaling up to this size is an investment, but growing a 12-foot tall photoperiod cannabis plant is incredibly fun and highly rewarding. The bigger the root zone, the heavier the bag. It pays for itself rapidly—the return on your investment literally outweighs the pot.

Because scaling up means you won’t need to buy weed for well over a year. We leverage decades of commercial cultivation expertise, plus the insights from helping 25,000+ home growers, to ensure you successfully pull down a massive, multi-pound outdoor harvest. We designed this large outdoor expansion kit to make it incredibly affordable and straightforward to multiply your giant cannabis plants right in your garden, on a spacious patio, inside a greenhouse, or anywhere your backyard gets intense summer sun.

From day one, you can skip paying for extra mini pots or rooting boosters you already have. To maintain your expanding outdoor garden throughout the summer, you literally just add water to the living soil. We prepare you for a massive, low-effort “Croptober” by stripping out the redundant accessories like watering cans, sprayers, trimming scissors, or macro lenses. You supply the seed and the tools you already own; we supply the giant, nutrient-dense root zone. Paired with our expert email support, scaling up to grow massive weed plants at home has never been lower effort, cheaper, or higher reward.

Loaded with a powerhouse of natural ingredients, beneficial microbes, and mycorrhizae, this large-capacity soil volume provides the sustained, long-term nutrients your giant weed plants need to mature into the fall. It effortlessly supports dense, resinous yields, giving you the ultimate expansion reward: a massive multi-pound harvest and significantly more weed than you need.

Where to Grow Me

outdoor cannabis grow icons garden, backyard, greenhouse

Our 35-gallon outdoor expansion kit is designed for the sunniest spot in your backyard with the least shade. Full sun weed growing ensures the biggest vegetative growth and a massive cannabis harvest. Place this large fabric pot on a spacious patio, open garden, or dedicated greenhouse, and stand back as your outdoor crop explodes in height. Because it scales so dramatically, expect your large outdoor weed plant to need at least a 4×4 to 10 x 10 foot area at full maturity.

Lighting Needs

How to grow cannabis in full sun

Direct sunlight is 5x more powerful than a 1000-watt indoor grow light; nothing fuels massive outdoor cannabis plants better than the raw sun. You will see this firsthand watching the explosive vegetative growth as your weed plant shoots up several feet each month until harvest. Place your 35-gallon expansion pot in the absolute sunniest spot in your backyard. The more intense sunlight it receives, the longer your photoperiod strain stays in veg, allowing your plant to grow significantly bigger.

Varieties & Planting Info

Our 35-gallon outdoor expansion kit is intended exclusively for open backyard or greenhouse weed growing. It provides the massive root zone needed to grow huge photoperiod cannabis strains throughout the full season, easily reaching heights over 12 feet. Alternatively, run a large early-flowering photoperiod strain and replant for two massive outdoor harvests in one year. While it will push giant autoflowers to their absolute maximum size, it truly shines when paired with vigorous, large-growing photoperiod genetics to maximize your overall yield.

Grow Results & Customer Reviews

This size kit should be our best-selling product, but it is our least. That’s probably becuase of the sticker shock of the price point. But every customer who has bought this size as made that back in savings. With some growers harvesting more weed than they need for years. It grows big, beautiful plants, and it has been proven to do so in my garden and our customers’ year after year.

How much can I yield?

How much you can yield off six big outdoors marijuana plants 10 pounds of weed

Outdoor 35 Gallon Grow Kit – Expansion Kit

1 Pound or more Per Pot

Grow up to 10 pounds by the end of the season. Several factors influence your outdoor grow and the harvest of 10 pounds of weed; plants started in April can easily exceed 12 feet tall. Seeds planted later, like June 1st, reach about 8 feet, while August plantings grow around 4 feet. With six of these large expansion pots in your backyard, you can effortlessly achieve that massive canopy each year. The two main factors are starting early in the growing season and maximizing direct sunlight.

Super Soil indeed!!

I’m heading into my third year of growing all my own marijuana. I couldn’t do it without the wonderful products from Pot4 Pot!! They make growing easy and the results are stellar! My outdoor plants range from 4 to 6 feet tall and indoor plants somewhat smaller. I can grow year round in Montana thanks to ILGM and Pot4Pot! I order the 35 gallon kit as a great refill supply for the 8 five gallon pots that I can grow legally in my state. If you are just starting out, or an experienced grower looking for an easy way to grow, this is it!
