Humboldts Secret Base A & B Bundle – World's Best Base Nutrient System – Liquid Nutrient/Fertilizer for Outdoor & Indoor Plants – Supports Vegetative and Flowering Stages of Plants – (2.5 Gallon Set)

I use for for my lettuce, basil, cucumbers and Goya (bitter melon). The standard A and B solution works well by it self for leafy greens, but I find by adding Golden tree to the mixture it works better when the flowering/fruiting starts. Since I am in Japan everything available to me to for measuring is metric I use 2 cc/mil of fertilizer per liter of water, and 1 1/2 cc of golden tree per 5 liters of water. I came upon this formula by trial and error and it works for me, but your milage may vary. I generally make 5 liter batches so I use 10cc of A, 10cc of B and 1 1/2 cc of golden tree.A tip is if you can get ahold of medical syringes without needles it is easier to measure. Just draw it up in the syring and squirt it in your water.

This was pretty basic as far as use , results have been noticeable through out my grow. This is my second grow . First with humbolt secret . I got bigger yield , quality buds I was amazed they were firm n frosty . One word of caution . When using golden tree do not I repeat do not spill it . It has a smell u won’t soon forget. Lol

This is a good base nutrient for your ladies. Has calcium and magnesium on top of a solid NPK. Size leaves something to be desired but it’s a good way to try it without being stuck with it if you don’t like it. I will be buying more.

I was worried about the extra effort of a 2 part system as I'm not the sort to measure everything out perfectly or take photos of my plants to share with a community. I can be a bit neglectful at times even. But this stuff seems to have given me much better results than some of the other products I've used including others from Humboldts.

I bought these last year and I will always get them

The media could not be loaded.  Great product first time grower and my plants are doing wonderful

Yep

a little expensive, BUT so far producing instant results you can see the next day!
