    • Excellent Combo Kit Fertilizer for Cucumbers In A Water Barrel
Size: 2.5 Pound Kit
I have a 55 gallon blue plastic water barrel. I started a cucumber plant in a 2" container. I filled the container with 55 gallons of water and the correct proportions of this Master Blend Fertilizer just to 1/8" of the bottom of the Cucumber Container.. one has to leave enough air space for the plant to breathe. The growth of the cucumber is amazing! It puts roots down deep into the water and makes many excellent cucumbers. Here is the ratio of the mixture you need for cucumbers in a 55 gallon barrel. Ingredient #1 Master Blend 4-18-38 (120 Grams for 55 Gallon Drum) Ingredient #2 Calcium Nitrate 15.5-0-0 (120 Grams for 55 Gallon Drum) Ingredient #3 Epson Salts (60 Grams) Note: Epson salts are HARD TO DISSOLVE. Use hot water in a separate pail to dissolve it. Next, mix all 3 ingredients together. Fill a 55 gallon barrel about 1/2 full and pour in the fertilizer mixture. Fill the barrel up to ONLY 1/8" into the transplanted cucumber container. It works in a 2" BUNG HOLE or if you use a 3 or 4 inch container, you'll have to TIGHTEN both Bung holes and then cut a hole to fit the size of your container. There is enough water and fertilizer to feet the cucumber plant for the rest of its producing life. Use a trellis to make it grow upwards to make it easy to gather your cucumbers.. else the plant will flow over the side of the barrel and onto the ground. Note also NEVER use a WHITE barrel. These barrels do NOT stop UV ray's and will form algae. If that is all you can get, paint it blue or black. The blue barrels have UV inhibitors built into them and will last for many years. ... show more

    • Great results great cost
Size: 12.5 Pound Kit
I've used more expensive fertilizer with considerably less results than this master blend formula. It's hard to beat this. I use it in a hydroponic garden and pre mix hyper concentrations of each of the parts into 3 different 1 liter bottles then just take a few mls of the liquids and mix them in my water. So far it's been working wonderful. Quick easy and way less expensive than the previous nutrients I was using. ... show more

    • Product is good. Shipping department made a mistake.
Size: 12.5 Pound Kit
I did not receive my full order and had to contact the company through Amazon. They apologized and sent out the rest of my order. I have used MasterBlend for several years and have found it to work well in my hydroponic set-ups. A little goes a long way.

    • a big change in results!!
Size: 12.5 Pound Kit
I have a hydroponic garden since the last 6 months, and I could see results only in the slowly growth of the plants. Now, I changed the mix in the water using MASTERBLEND 4-18-38 Combo kit and day by day the results turn into fruits in the garden. It was an enormous change. It is very easy to use ONCE you do the math for small quantities like in my case. ... show more

Review Image by E. Dichoso E. Dichoso
The media could not be loaded. It's my first time to try hydroponics and this product was highly recommended by my friend. I'm pleased with the results so far. In a couple of weeks, I was able to grow some lettuce and bok choy and I'll be harvesting the vegetables in 2-3 wks.
