I've been a long time user of GH Flora series, I have amazing results with the part of the line I have used, and have spent hundreds if not thousands of hours playing with numbers and research. The end of it all has lead me to let the plants tell me what they like (listening very intently). I believe this is an invaluable skill to learn as it cannot be taught. I have used Koolbloom dry and liquid for years in ALL combinations. I have come up with what I think is the best way to use it. At the beginning of week 3 give 1/2 strength, I do res. changes every 2 weeks, and go average 10 weeks.
Week 3: 1/2 strength
Week4: res change 1/2 strength
Week 6: full strength
Week 8: flush till done.
You need to flush this out well before harvest or it will become a problem. i.e. Black ash, joints not staying lit. But a long cure will correct this.
Looking for something bigger and better and for the sake of maybe doing better I tried Humboldt Counties Own Sonic Bloom after being told for months that it's better than dry Koolbloom. It does volumizes the buds about 20% larger, it doesn't back it up with the solidness that the Koolbloom adds thus not yielding as well. I used the same schedule of 1/2 strength and the same schedule as Koolbloom because my recipe is perfect for what I do. I'm not going to say that Sonic bloom is worthless but I'm going to continue experimenting with both together at different times. Sonic bloom is better in the first half of using it than Koolbloom, but Koolbloom adds a density that the sonic bloom does not. This is across a couple years of testing across many different strains. I grow rdwc and average 18oz per 3x4 screen. Again, they are both great, and both together might be the best, if I had to buy one I'd buy Koolbloom. Both, if I had the money.
