User questions & answers

Question:	Is this fertilizer good for phalaenopsis orchids? It has a high urea nitrogen content, so was just wondering whether it's still optimal for phals
Answer:	22"H x 17"W x 6"D (or 8"D when expanded). These are approximate, as it is a soft side--you could probably get it out to 9" or more depth if you really packed it in there and put the zippers to work.
Question:	Anybody know the ratio for DIY misting spray
Answer:	I'd agree with AL's 50L. I have both this and the Hynes Eagle 40L, and this easily has 25% greater capacity than the Hynes. Fully expanded, it's comparable to a domestic-sized roll-aboard suitcase.
Question:	What are the proportions of NPK in this orchid fertilizer
Answer:	It is a nice back pack with neat features. But, it is a $40 backpack. I would consider it a medium duty travel pack, and would not recommend repeated over loading. I have a $300 Gregory pack constructed with rip stop material and zippers that are double the size of the ones on this pack. With that said it is a great backpack for the money!
Question:	What are the ingredients
Answer:	My wife and I just returned from a trip to Europe where we flew Norwegian, RyanAir, and Flybe. I used a different bag, while she used this AmazonBasics bag. None of the airlines measured our backpacks and we were able to carry on for all of our flights. Flybe was the tightest in terms of getting the bag in the overhead bin, but it did indeed fit. Just don't over pack, and you will be fine. For Norwegian and RyanAir, we had zero issues getting the bags in the overhead bins.

User questions & answers

Question:	How often should i use the pellets? i am assuming once a week but i don't see the frequency of use mentioned anywhere and i didn't want to assume

User questions & answers

Question:	How much should I spray per plant? 6 inch potted phaleonopsis and 1 cattleya
Answer:	There is actually a picture of orchids on the front of the package. I think it's great to use on orchids - perhaps not as the primary fertilizer - but it is excellent for foliar and root spraying. It helps increase the humidity while giving them a light feeding. As a primary fertilizer I would probably go with a higher middle number fertilizer.
Question:	Can I use this for air plants
Answer:	The instructions are on the bottle. I use one teaspoon to a quart of water. It has made all my older orchids that used to throw away, bloom! Really nice
Question:	Can this product be used on Spathiphyllum
Answer:	30-10-10
Question:	How long does an 8 oz bottle last with weekly spraying? The two pack seems like a lot
Answer:	It is 30-nitrogen 10-phosphate 10-soluble potash. It has everything in the mix that you need for root feeding with the measuring spoon in the box. All you need is a gallon jug to mix it in so that you don't mix it to strong and you can use extra feedings from the same jug. All mixing and feeding directions are on the box. Buy the spray for misting the leaves but don't spray the flower buds. I have city water so I buy bottled distilled water to mix it in so I don't add unwanted chemicals that can harm the orchids. One gallon goes a long way. I also bought special orchid pots from orchid.com and sit it in an old plastic whip cream bowl then add about 1/4 inch of the watering in the bowl for humidity and continual wick feeding into the wood chip mix for more of a natural balanced feeding because the roots grow up into the air and these pots have mesh bottoms to hold the mix and large side vents that the roots grow out of. My orchids bloom almost 9 months out of the year with this method and they grow like crazy. I wish I had bought the pots with open slits for easy repotting but I didn't expect them to grow so huge. Orchids also want a snugger fit than most house plants. They also Love east or north windows as long as there is indirect lighting no west or south windows without frosted sheers and no drafts from vents. My orchids are thriving in 68-72 degree temps all year round. Orchid.com also has some very good free informational videos on how to propagate and repot orchids and other information on blooming cycles. They also carry more natural potting mixtures made from different tree barks and such in different textures. Enjoy your orchids and I hope this helped.

Product description

Orchids are a unique and beautiful houseplant. They are prized for their rare colorful flower spikes, beautiful dark green foliage, and can make an ornamental decoration in your home display, bathroom, wedding, office desk or patio garden. Live orchids can bloom in an array of wild colors, including; blue, black, white, red, yellow, orange, purple, gray, gold, teal and violet. Our orchid fertilizer is ideal for a variety of orchid species including: epidendrum, brassavola, catasetum, calanthe, lycaste, mokara, renanthera, falcata, loddigesii, bulbophyllum, liparis, disa, cranefly, ludisia, pusilla, aerides, tolumnia, miltassia, ascocenda, aerangis, sobralia, beallara, angraecum, masdevallia, violacea, vandas, phragmipedium and bletilla. Aquatic Arts Orchid Food is the best choice to help your orchid grow big and healthy! Potted plants require additional nutrients to help them thrive. While there are many other products on the market, our pure gentle formula makes this orchid fertilizer a prime choice to help your plant grow healthy and beautiful. There are 3 key factors in the health of your house plant: Light: Orchids will thrive in bright indirect sunlight, how much light your orchid needs will depend on which specific variety of orchid you own. Water: You should water until the substrate is moist and water runs out of the bottom of the orchid pot. If you water too often, it can result in root rot. A good orchid potting mix includes bark and clay. You can also place the orchid pot with holes for drainage inside a decorative container. Food: Your orchid needs nutrients to promote healthy and hardy growth. Our orchid fertilizer is formulated with a ratio that is ideal for orchids. When properly diluted our fertilizer is gentle enough to be used every time you water, with no risk of burning. How to use: Add 1 teaspoon of our orchid fertilizer to 2 cups of water and water your orchid about once a week for optimal growth.

• Feed your Orchid: live indoor plants need nutrients, in addition to light and water to promote healthy growth and prevent brown spots on leaves.
• Long-lasting: dilute one teaspoon of our liquid fertilizer with 2 cups of  water. An 8 oz bottle Should last 6 months - 1 Year.
• Gentle formula: designed to be gentle enough to use every time you water with no risk of burning.
• Raw nutrients: nitrogen (N) promotes growth of new stems and leaves, phosphorus (p) is a root stimulator, aiding in root growth and helping heal root rot, and potassium (K) helps your Orchid grow large and healthy.
• Specially formulated for orchids: can be used to feed: Phalaenopsis, Dendrobium, Cattleya, Cymbidium, Vanda, moth, paphiopedilum, Oncidium, zygopetalum, “Bat plants”, livilan, laelia, and neofinetia.

User questions & answers

Question:	Is the product urea-free
Answer:	I use once a month
Question:	Can this be sprayed on the leaves of plants? Want to use it for my hoya plants
Answer:	Do not do the “Ice Cube” method of watering! The roots shoot out of the holes and up to the surface for air and moisture. Put the fertilizer in the pot and use a cho stick or fork to get it down in the medium mix. Then put your plants in the sink and gently shower. Depending on your location geographically and in your home (north south east west) exposure water accordingly.
Question:	My orchid hasn't bloomed in 2 years, it has green foliage so it is not dead. should i try this fertilizer? any other suggestions? thanks
Answer:	Oh no, I'm so sorry to hear that. It should be included, but sometimes Amazon ships without pieces. Please email me [email protected] and I can send you a replacement right away. Thanks, Claire
Question:	what is the NPK ratio? Can't find this information any way on this page
Answer:	Yes you can! It's a spray and it's gentle enough for use each week on any variety. Hope that helps, Claire

Vibrant Leaves

Nitrogen promotes bright green leaves. Even when orchids are not blooming they can still be beautiful with vibrant foliage.

User questions & answers

Question:	Can I use this in combination with orchid food spray
Answer:	The bottle doesn't give you a good idea, so I've been using about 6 spritzes on each 6 inch pot, with no ill effects, and in fact, my orchids are blooming regularly, with only a slight rest between bloom cycles.
Question:	When can you start seeing results
Answer:	Hi there! This product contains nutrients that are specifically beneficial for orchids, and air plants may not respond as well to it as an orchid would. Let us know if you have any other questions!
Question:	I don’t see any reviews with results/photos to show orchid growth. Can anyone give me an update about how it worked
Answer:	I use this on all my air plants. It is basically nitrogen but I always make sure the plants are wet by misting them first. Some plants may be sensitive to this. I also don't spray on any flowers, just a quick spritz on the base of the plant or on the soil if it is a potted plant.
Question:	Is this orchid food product good with ceramic pebbles
Answer:	It depends on how many orchids you are feeding. I have 7 and I spray them thoroughly. A bottle lasts about a month or so. Hope that helps you to decide.

Don't Be Fooled by Liquid Fertilizers

Liquid applications require unnecessary attention and care. Most liquid fertilizers need to be applied on a daily basis in order to reach full enrichment. This is time consuming and not cost effective.

Applying Pellets is Easy!

One application provides 6 months nutrient enrichment

• Sprinkle 1/4 teaspoon fertilizer per 2-inch diameter pot size.
• Distribute pellets evenly around container.
• Water thoroughly after application

Ideal Growing Conditions

• The Orchid and Epiphyte family enjoys acidic soil conditions — meaning the pH balance measures at or below a 6.
• These flowers enjoy a lot of light — they prefer filtered or rebounding sunlight throughout the entire day
• Overall temperatures ranging from 65F-80F both during the day and at night
• Water once a week with a spray bottle or by placing ice cubes in the container and allowing them to melt

• Carefully place your Orchid into its container, making sure not to damage roots, stem, or petals
• Backfill remaining space in container with more potting mix, do not suffocate roots

Question:	I am new to orchids. I purchased 5 very small ones;each is in a plastic insert in a 3" clay pot. How often & how much should I water/feed them
Answer:	Hi. I am a member of my local orchid society. The guideline we use is 'weakly weekly' so 3 weeks out of four fertilize with a solution using half of the suggested amount on the label. 4th week just water thoroughly. Be sure to water before you fertilize. Would recommend you join your local orchid society. Some plants have different watering needs than others.
