Humboldt Nutrients Own Sonic Bloom with Vitamin B1 Flowering Booster 100gm 0-51-34 Hydroponic Fertilizer

I did a side by side grow, plants with bloom booster were three times bigger after 2-3 days. I had another brand of pk booster, it worked pretty good also but not as good as sonic bloom. Im going to add some B1 next time to see if that will close the gap a little. It's a little pricey, but it works, I can probably duplicate it for cheaper, but then there is more time involved. It is a good product, you won't be disappointed

(Currently using, will update after grow season.)Positives are; it can be used without fear of fertilizer burn.Negatives; measurements are given for 5gal mixes so there is some quick math needed for 1gal batch.

It's alot cheaper in your local stores. Problem was I couldn't find it locally. It's an awesome product. It makes your buds bigger amongst other things. If you're growing marijuana you need this!!!

AMAZING!!! We have applied this to our vegetable garden and house plants and it has brought everything back to life. We had a hornworm eat two of our pepper plants all the way down to the stalk and we applied this in a spray bottle and within a few days they started growing new leaves and are looking great! Our tomato plants are a beautiful healthy green and we have larger tomatoes too! A deer ate the ends of our cucumber plants and they also have grown new leaves and are healthy again. Within days this works. Well worth the money!

Easy to Measure and use leaves buds super happy n thick more then worth the money 20% ish increase to yeild

I noticed a great difference in size when used correctly and over a few weeks. It didn’t throw my ph off really. I have no complaints and will keep it in my nutrition schedule.

Excellent product will definitely buy it again

This won't take the place of not enough light in the grow stage (causing stretching and this not super nugs) BUT it will maximize what you have and that is really good. Because there is no nitrogren per se, you can add a lot without worrying about burn or overwhelming the plants. Also the plants had an even better taste as a result of its use up to a few days before harvest. Nice.
