tl;dr: Jacks 321. Update. It looks as if the seller is no longer selling bundled kits, but you can still purchase individual items 15-12-26 | 15.5-0-0 | Epsom Salt
Below are instructions for feeding your girls; however, in the absolute, you should know that plants only require three essential nutrients, Nitrogen (N), Phosphorus (P), and Potassium (K), often seen as NPK or some concoction of a three-number array. We strongly believe Oxygen (O) to be the fourth basic, but since nobody has figured out how to charge for it (actually, see air pumps), we’ll focus on the big three.
Pro Tip: #dontbuywater
Without getting too technical, our suggested nutrients are the same ones used by commercial hydroponic grow operations for food production Linked is Jacks 321, which is reduced weight and size and is perfect for our grows using a five-gallon bucket as the reservoir that serves four plants. Typically the nutrient is sold in large bag quantities, which in our systems would last forever. I haven’t done the math, but a typical grow is 13 weeks, and you’ll get more than three matures or more out of this package, so kudos to whoever takes the time to break it down.
Understanding basic plant requirements should force you to abandon purchasing liquid nutrients as you pay for water.
The best advice, for starters, is to focus more on environmental conditions and less on expensive nutrients. In our experience, oxygenating the root system produces #rootporn.
Doing Jack’s 321 in a 5 gallon
This three-part is simple as long as you get a scale that removes any guesswork. Label three red solo cups with a one two three. Nutrients are applied to the system from seedling until chop. Seedlings give enough time (about a week – they can go longer) to use the nutrients provided at birth.
Labels: one 15-12-2 18g | two Epsom Salt 5.5g | three 3.12g 15.5-0-0
1. 18g 15-12-2 (fine)
2. 5.5g Epsom Salt (course)
3. 12g 15.5-0-0 Calcium Nitrate (in-between)
For some reason, the order matters; however, for our system, we run the pump while recirculating the nutrient solution and giving the plants a nice breather.

Every Deepwater culture system requires nutrients to be changed weekly, especially during the flowering cycle. Pay attention to weekly nutrient changes while using Jack’s 321, and you’ll start to believe you know what you’re doing.

The Holy Grail of Hydroponics
Are you looking for a more efficient and cost-effective way to grow your plants? Look no further than Bottleponics! This innovative hydroponic system combines the benefits of deep water culture and ebb and flow systems to provide your plants with the perfect balance of water, nutrients, and oxygen.
With Bottleponics, you can grow your plants using minimal growing media in small containers, such as 1-gallon buckets. This can be especially useful if you work with limited space, such as in a grow tent. Using a pump and irrigation tubing allows the nutrient solution to be circulated and aerated, which can benefit plant growth. Additionally, the roots having direct access to air can help prevent common issues such as root rot. At the same time, using smaller containers can be more cost-effective than larger containers or blocks of growing media.
One of the most significant advantages of Bottleponics is its versatility. This system can be easily adapted to fit your growing needs and goals, whether you are a beginner or an experienced grower. So why wait? Give Bottleponics a try and see the excellent results for yourself!
