Our Kit Has Everything Needed To Grow Weed

The Bare-Bones Essentials for Expanding Your Indoor Garden. Maybe you already know how to cultivate cannabis and just want a quick, convenient reload for small grow tents. We aren’t here to hold your hand or charge you for beginner equipment you already have in your grow room. Our cheap 2 Gallon Expansion Grow Kit is stripped down to the bare essentials, designed specifically for experienced cultivators who need to scale up their indoor cannabis harvest efficiently.

You get exactly what you need to run another cycle or fill out your indoor canopy: our heavy-duty 2-gallon aeration fabric pot and a fresh charge of nutrient-dense Superb Soil.

We’ve done the heavy lifting on the soil biology so you can focus on maximizing yield. Just drop in your seed or clone, add water, and let your experience take over. This is the most cost-effective living soil system, saving you extra overhead and the back-breaking work of mixing your own super soil and sourcing ingredients.

Fully Loaded Super Soil - Just Add Water

Ultimate organic living soil for cheap indoor weed growing. Skip measuring confusing synthetic fertilizers, which can easily burn your plant with one overfeeding. Our exclusive Superb Soil provides an active, nutrient-dense environment engineered to nourish your compact plant from seedling to yield. Use our 2-gallon system inside a grow tent; simply add water, and it slowly releases natural amendments to provide an optimal feast for a heavy, resinous harvest. Drop your autoflower seed, add water, and harvest pure, clean cannabis in exactly 80 days.

Where to Grow Me

Our 2-gallon pot thrives in spots that get over 4 hours of direct sunlight, like a bright window or a sunny balcony. When cultivating autoflowers inside, a dedicated grow tent isn’t strictly necessary. You can easily manage an autoflower living room grow using supplemental LED lighting. Move it outdoors during the day and inside at night. It also produces fantastic yields inside a standard tent. Ultimately, this expansion kit is highly versatile for indoor cannabis growing, ensuring your weed plant remains perfectly compact and short.

Lighting Needs

How big your cannabis plant grows and how much it yields depends entirely on your lighting. While natural sunlight is excellent for your 2-gallon pot, providing over 4 hours of direct light daily for a healthy autoflower, indoor setups often need help. A sunny apartment window works well for partial exposure. However, if you have limited sunlight or grow discreetly inside a small tent, use an LED grow light. You’ll need at least 40 true watts to supplement partial sun. For completely sunless indoor growing, 75 watts to 400watts is required for a heavy yield.

Varieties & Planting Info

Our 2 Gallon Expansion Grow Kit is perfect for cultivating autoflowers indoors under LED lights or inside a small grow tent. This size keeps plants short and dense, ensuring a compact, highly discreet canopy. Grow autoflower seeds efficiently, even stretchy sativa-dominant strains, allowing you to maximize cannabis yields in tight indoor spaces. When running photoperiod varieties, keep your vegetative phase brief under indoor grow lights.

When to Plant?

Outside – Start autoflowering seeds indoors as early as March. Grow outside between April and the end of October.

Indoors – Year-Round in a sunny window. Or in a grow tent.
