Humboldts Secret Everything Indoor Plant Food with Kelp | Liquid Concentrate Indoor Plant Fertilizer 3-3-3 All Purpose Plant Food for House Plants (8 Ounce)

Seems to work just as well as any brand of fertilizer. I always use my fertilizers (any brand) ultra-diluted so there is no risk of burning roots.

I’m by no means a plant expert, let me be very clear about that. I’m barely knowledgeable enough to keep plants alive. I can’t tell you much about the balance of nutrients in various plant foods, I just know plants often need more than just the soil they’re in and I’m trying to give them that.This is easy to use, I really like that you can measure in capfuls rather than having to pull out measuring spoons. You mix it with a lot of water then pour it on your plants. Easy. Most of my plants have done well, a couple had some leaves start looking not so happy but I can’t say if it’s because of the plant food or because it’s an incredibly dry winter here and that’s affecting them.So for the most part it seems to be doing well. I have a variety of types of plants ranging from monstera to calatheas to coffee trees and spider plants. They’re all over the board. I’ll keep using this and see how it goes. Overall seems to be fine, at most I might stop using on 1-2 plants but the others seem happy enough.

I have been really getting into my gardening hobby this year and learning to more properly take care of plants, which is why I decided to order this plant food for them. So far, they seem to like it, so I do too. First off, the measuring system is handy for mixing this solution to dilute it in water. Most plant food I have to find something to measure it with, but this one is just one capful, so it makes it convenient and easy. My plants seem to be thriving so far, and I haven't noticed any side effects or issues from using it. However, if for some reason I get evidence to the contrary, I will stop using it and update my review.Overall, this product has met my expectations, is easy to use/dilute, and appears to work well for my plants, so I would recommend it to others in the market for plant food and I would consider ordering it again.

First - I've been in the horticultural industry for over 30 years. Certain things I always look for..when I saw the listing - it did not say the source of the fertilizer. Yes it does say "with Kelp" But not specifying how much. Also it did not say anything about organic. So I decided to get the actual product. Yes hopefulThe main source of the nitrogen is Urea, the cheapest nitrogen you can get. The fourth ingredient on the list is kelp, behind Urea, Phosphate and Potassium then Kelp. So you know very little of that.On top of all that this is overall a very low analysis.Will it work, of course, if you use enough.But at the analysis and price, I feel there are many many much better options out there.If after using it and giving plants a few months - If I am WOWED but the results I will update my review

Wasn't familiar with this brand, so I did some research on the company and scoped out the reviews on their other products, which tend to consistently get very good reviews. While those things don't impact how *this* product performs, it gives me confidence in the brand and product overall, and makes me more comfortable trusting their claims regarding ingredient sourcing and ratios.One of the product images mentions this product being "manufactured in our San Diego facility" but I don't see any mention on the product packaging itself of being made in the US or where the ingredients are sourced from. I only get super picky about such things when the product is being used on plants that may find their way into my body at one point or another. For decorative plants, I'm less concerned.We've got a lot of houseplants that tend to be "hanging on by a thread" at any given time, due to busy schedules and general neglect. Most of the time they're lucky to get watered on a regular basis, let alone fed with plant food or fertilizer.This stuff mixes up easily in water as per the directions and seems to be giving my poor houseplants a perk. Very pleased with this so far, especially for the price. If I encounter any negative issues later on, I will update this review.

I have been giving my plants this supplement once a week for about a month. So far they are all still alive- so that’s a positive. I don’t have a green thumb at all so I guess it seems to be doing the job so far

This fertilizer seemed to work decently- I don't typically fertilize my plants and they seemed to like it! It doesn't have a smell but does have a medium amber color. Simple and easy to use.

This could be working but I don't really see any changes in plant growth yet. I dilute it with every watering as I put fertilizer in my watering can for all of my house plants. After about 3 months I don't see really any growth, Color, Or rooting changes. Ill use the entirety of the bottle to be sure its just not the dilution causing the slower growth but never been an issue with other liquid fertilizers.
