HEAVY 16 USES A POWERFUL COMBINATION OF MINERAL AND NATURAL INGREDIENTS IN A SYSTEM THAT IS STRAIGHTFORWARD TO APPLY AND MAINTAIN

  • Bringing the flavor with HEAVY PRIME ๐Ÿญ๐Ÿ“

Top-shelf flower starts with flavor, aroma, and resin-rich potencyโ€”and thatโ€™s exactly where HEAVY 16 PRIME shines. ๐ŸŒบ๐Ÿ”ฅ

PRIME is a powerhouse microbial feed and sweetener, crafted to elevate oil production, boost brix levels (hello sweetness + density), and bring out those unique terpene expressions that set your cultivar apart. ๐Ÿ‡๐Ÿ‹๐ŸŠ

While it doesnโ€™t contain live microbes itself, PRIME supercharges the effectiveness of your microbial inoculants, compost teas, and enriched media. Itโ€™s the missing link that brings everything together, feeding the underground life that fuels explosive above-ground quality. ๐ŸŒฑโšก๏ธ

Use it through the entire life cycle to dial in plant performance, push genetic potential, and unlock flavor profiles that hit like no other. Taste, smell, potency: PRIME makes sure theyโ€™re ALL unforgettable ๐Ÿค˜

  • Need some tips on how to use HEAVY Foliar? You came to the right place! ๐Ÿ“

HEAVY FOLIAR is highly versatile and can be used alone or with other products. Mixing HEAVY FOLIAR with HEAVY ROOTS and HEAVY FIRE allows a for a comprehensive nutritional delivery in both phases of plant development. HEAVY FOLIAR can be mixed with pesticides, fungicides, soaps or oils.

We recommend spraying every three days for optimal nutrition uptake. If you prefer to spray every day, we recommend using the HEAVY FOLIAR recipe at half strength. For best results, spray your crop from seedling up until the fourth week on flowering crops. Please note that there is no need to adjust the pH of the FOLIAR formula after mixing, but that FOLIAR should be sprayed within three days of mixing!

๐ŸŒฟ Mix HEAVY FOLIAR with water, adding HEAVY16 Products in order as listed on the schedule on our website

๐ŸŒฟ Lightly mist plants every 3 days during foliar periods. Avoid drenching foliage.

๐ŸŒฟ You can spray HEAVY FOLIAR lights on or off; our recommendation is to spray at first light.

๐ŸŒฟ Do not adjust pH of FOLIAR mixture.

๐ŸŒฟ Use FOLIAR mixture within 3 days of dilution with water.

๐ŸŒฟ An oily sheen on leaves is normal.

  • No need to pH when youโ€™re running HEAVY ๐Ÿ’ช

PRIME, our centerpiece, sets the pH for you via complex organic acids! If your water source is roughly between 5.5 and 8.0 on pH scale, PRIMEโ€™s complexion will naturally titrate pH, eliminating the need for hard acids in the garden ๐ŸŒฑ

One less step in your routine so that you can spend time where it matters most! ๐Ÿ˜Ž

  • Why no Air Stones? ๐Ÿซง

We prefer to avoid continuously churning and bubbling HEAVY 16 reservoirs to preserve the fine organic acids that, if over-stimulated, will volatilize quickly and lead to a rapid pH rise when holding a reservoir for more than a few days ๐ŸŒฑ

If biology is used in the reservoir, artificial churning and oxygenating will exacerbate the situation as most bacteria create hydroxide (pH up) as a byproduct of heightened metabolism - which is promoted via air stones, etc. Additionally, most air pumps that power air stones draw in large amounts of CO2 from the room, which creates carbonic acid and lowers the pH ๐Ÿ’จ

To oxygenate correctly, simply leave a submersible pump at the bottom of the reservoir to break the surface tension and prevent stagnation. Your media or system should have more than enough aeration to functioning optimally ๐Ÿซง๐Ÿ’ง

  • FINISH is the final statement! ๐ŸŒฟ

This all-natural bio-regulator transforms water at the molecular level, making it more active and able to penetrate deeply into soil and media. It balances electrochemistry by donating and receiving electrons, unlocking the full expression of your cropโ€™s genetics ๐Ÿงฌ 

Use it in your final week to reclaim tired soils, buffer EC and pH, and purge out residual salts or heavy metals from sub-par regimens. Its natural chelating structures are lab-refined to a uniform size that cleans far deeper than typical finishing products ๐Ÿ’ฆ 

Expect deeper color, heavier oils, and richer aromatics during flower senescence โ€” the kind of results that elevate good runs into great ones. Some growers pair it with Heavy Prime for extra terp lift, others run it solo with pure water for a clean, powerful finish ๐Ÿ”ฅ 

However you use it, Heavy Finish is your go-to for the final flush that actually finishes. ๐Ÿ’ง๐ŸŒฑ

  • Donโ€™t forget HEAVY16 can be used on seedlings and cuts! ๐ŸŒฑ 

Found in the first column of our feed cards, or at https://www.heavy16.com/nutrient-
calculator/. As shown, values are per gallon. 

You can pretreat with this solution for increased success rates during propagation as well as feed your freshly rooted seedlings or cuts! ๐ŸŒฟ

#ROOTS will promote root development while stopping pythium and other possible infections in its tracks! Less damping off... more growing up!

Once rooting has started the low levels of our VEG base will help maintain growth, eliminating the nutritional stress in that transition for the little ones.
