This stuff is awesome!!!!! If you want more flowers or fruiting sites this is the stuff for you. Most customers report that their increase is 50-200%. Make sure your plant can hold up the extra fruit or your plant might lose branches.
Add 1 3/4 teaspoons of ThunderBloom to each quart or liter of water. Mix thoroughly before lightly spraying top and bottom of leaves. Start 5 days before turning lights to a bloom cycle, switching to a bloom fertilizer or both. Spray once a day for 10 - 14 days.
Also, make sure to mix in a surfactant (spreader sticker) with this product before you spray. Surfactants mixed into the water before you add your Thunder Bloom Foliar Spray will spread the product over the leaves evenly and coat them. Always spray to tops and bottoms of leaves when foliar feeding. In a pinch you can use a clear dish washing detergent like Ivory liquid. Make sure there are no anti-bacterial additives in it. Use about 2 to 3 drops per quart. Start with the lesser dose and spray a small area. The leaves should look coated. Look closely to make sure the spray is not beading up and running off of the leaves. If it is, increase the amount of surfactant.

Update: You may use up to 4 teaspoons of ThunderBloom per quart of water without harming the plants and better results! Try spraying at different strengths to find out which one works best. You can start 10 days before switching to a bloom cycle if you like. Some people have reported plants going into bloom before the indoor 12 ON 12 OFF lighting cycle starts. Continue spraying for another 5 days while in 12 ON 12 OFF lighting cycle.
