    • Another great product from Advanced Nutrients
Size: 1 Liter Style: Fertilizer
Excellent product from A.N. Works great ! I use it starting at week 2 through week 5 . We have used many nutrient lines over the years here on the farm, and even though Advanced Nutrients is a few cents or a dollar more than some other nutrient lines, the extra expense is worth it . The return yield is extraordinary and the flowers are top notch. ... show more

    • Get Nice BIG buds!!
Size: .250 Liter Style: Fertilizer

I started using this supplement along with General Hydroponics Floria Trio, GH Liquid KoolBloom, and Advanced Nutrients Overdrive and it's been a game changer! I always had decent results without the Big Bud or Overdrive but wasn't quite where I wanted them to be. My dad recommended both Advanced Nutrients products and after seeing how huge his buds turned out, I bought them. The prices are a LITTLE high, but you don't need to use a lot, and it's only used during flower. With that being said, good quality product takes time and money, so it's worth the cost to me, especially with the end result. The supplement does not negatively affect plant health, nor does it affect the taste in the end product. I highly recommend for nice, thick, dense buds! ... show more

    • The "Gym Membership" Your Buds Didn't Know They Needed!
Size: 4 LITER Style: Fertilizer
Review Image by Dev Dev
If you want your flowers to look like they’ve been spending two hours a day on the bench press and chugging protein shakes, Advanced Nutrients Big Bud is the secret sauce. We’ve all been there: you’re midway through bloom, and your plants look... okay. But "okay" doesn’t win trophies, and it definitely doesn't fill up the jars. Enter Big Bud—the ultimate "bulk-up" supplement. The Dirty Details: Instant Thicc-ness: This stuff is like a push-up bra for your garden. It provides the exact ratio of Phosphorus and Potassium your plants crave during the peak bloom phase. Within a week, you’ll notice those flowers starting to stack and swell. The "Weight Room" Effect: It doesn't just make them look bigger; it makes them heavier. We’re talking about that dense, rock-hard quality that makes your trimmers complain about their hand cramps (a good problem to have!). Bio-Available Gains: Unlike some boosters that just sit in the reservoir like a salty rock, this is designed for maximum absorption. Your plants actually drink it up instead of leaving it to gunk up your lines. The Taste Factor: It’s packed with L-form amino acids. This means while your buds are getting huge, they aren’t losing their flavor or aroma. You get the size and the terpene profile. The Verdict: If your plants are looking a little "skinny-fat," it’s time to put them on a Big Bud regimen. I’ve tried the knock-off bloom boosters, and they’re usually just expensive bags of salt. This is the real deal. Warning: May cause "Branch Sag." You might want to invest in some trellis netting or plant stakes, because these buds are going to get heavy enough to break their own necks. Bottom Line: Don't let your harvest be a "what if." Give them the Big Bud and watch your canopy turn into a sea of heavyweights. 10/10 would bulk again. ... show more
