    Give your plants a “chill pill” during veg and bloom with B Vitamin Complex B from Kelp4Less. I use B Vitamin Complex to provide relief to my plants during stressful conditions such as transplanting and on high heat days. A plant that is more relaxed will experience more consistent growth and higher yields, than that of a unhappy depressed plant with many ups and downs. Please note this product is extremely potent so I would advise to use it as directed. 1/8 teaspoon creates 50 gallons so just a pinch in a 5 gallon, is the perfect dose. Choose B Vitamin Complex from Kelp4Less. It’s much cheaper than over price competitor products such as B-52 that are mostly water vs a wholesome dry powder product.

    I mixed this B Vit Blend as directed and used it on some new mini roses I just purchased at a better price because they didnt look too good. They can be hard to get, especially the Kordana variety from Quebec and they are my favorite of all the mini’s so thought I would use this Vit B on them. 72 Hrs. Later new green leaves, strong stems, and little blooms peeping out. The nursery thought they would not make it because they looked really bad. But the Kelp Meal with equal parts of Cottonseed meal, Alfalfa Meal, Bone Meal (or Kelp4Less’s Fish Bone Meal), and Black Cow Manure or Chicken Manure dry mixed into soil around new plants or in pots. Waited about 3 days and used Vit B as foliar spray and some around drip line. They are looking awesome in very short period of time. Very pleased with B Vits. It only takes a tiny bit, more is not better. This is a very potent Vit B Blend. Try it, you won’t be disappointed.

    I like kelp4less B-Vitamin because it is just as good but less expensive than B-52 and other overpriced B-vitamin products sold at most grow shops. Kelp4less is awesome and I refer a lot of customers here.

    I bought 8 oz of this amazing B-Complex for my indoor medical cannabis grown in soil. I use it with every transplant. I don’t really see any difference in growth, but the fact that I’m NOT getting any stunted plants I’m guessing it’s helping with the transplant shock and whatever else it helps with. I use it with Recharge inoculant when watering after transplant and with Mykos & Azos that I add to the root ball and around the planting hole 🕳️. People tell me I’m using too much stuff but it’s working for me plus 8 oz will last me at least 5 years but probably 10 because the use rate is soooo small.
