Big One by Top Crop is the biological trigger your plants are screaming for to switch from vegetative growth to beast mode flowering. This stimulator, based on plant extracts and algae, is not just another additive; it is a potent bio-stimulator that drastically increases the volume of your flowers and the production of resin, ensuring that every centimeter of your grow room is productive.
There is nothing more frustrating for a grower than spending months pampering plants, controlling the climate and pH, only to end up with "popcorn" buds that lack density and weight. You look at your jars and feel that, for the effort invested, the return should have been much higher. That lack of density not only affects the final weight but also the quality and bag appeal of your harvest.
If you don't stimulate the flowering process correctly from the start, the plant simply follows its biological rhythm without pushing its limits. This results in a mediocre harvest, where you lose up to 40% of the potential production you could have achieved. Basically, you are leaving grams (and quality) on the table simply by not activating the plant's internal hormonal system at the right time.
The solution is Big One. By applying this stimulator, you are introducing a shot of natural energy that forces the plant to produce more flowering sites and fill them with resin. Thanks to its formulation with alfalfa and algae extracts, rich in natural hormones, you ensure that your buds are rock hard, heavy, and covered in trichomes, maximizing the genetic potential of your seeds.
This product stands out among other cannabis fertilizers because of its ability to increase both the size of the flower and the amount of resin. Here is how its features translate into real results for you:
To get the most out of it, timing is key. Since it is a stimulator, you must use it just when the plant is preparing to bloom.
Pro Tip: For a complete fattening phase, combine Big One with SuperGuano Top Crop later in the cycle. This combo ensures the structure created by Big One is filled with density and weight.
Yes, absolutely. For autos, apply it via spraying when you see the first signs of flowering (usually around week 3-4) and then continue with irrigation applications.
Yes, Big One is 100% soluble and works perfectly in hydroponic and aeroponic systems without clogging the drippers.
No, as long as you respect the doses and stop using it at the indicated time. In fact, by increasing resin production, it can enhance the terpene profile, improving the aroma when you are harvesting and drying marijuana.
Yes, it is compatible with the entire Top Crop range and most fertilizers on the market. Just make sure to measure the EC so as not to over-fertilize.
I've tested dozens of boosters over the years, but Big One holds a special place in my rotation because of its efficiency-to-price ratio. I remember a test I did with a Critical strain: the plants treated with Big One via foliar spray 10 days before the flip developed significantly shorter internodes and much more aggressive early resin production than the control group.
My personal trick is not to skip the foliar application. Many growers go straight to irrigation out of laziness, but that first spray is what really "wakes up" the plant's hormonal system. If you do it right, the increase in the final weight of the dry bud is noticeable, easily reaching that promised 30-40% increase if the rest of the parameters are dialed in.
