It really works, but in very very small doses or it will burn the plants. I will use 0.8ml max per gallon especially with my small one gallon pots. Adding this in small doses over time makes a difference and I can see the resin forming the morning after I use it. I killed lots of plants over using this stuff, very powerful.
Not too bad for a small one gallon experiment. Didn't have enough dirt so I used mostly perlite and no nutrients for the first 4 weeks. Hits really hard great nighttime
