Plant-Prod MJ™ Boost 15-30-15 is a high phosphorus formulation that supplies the necessary phosphorus for transplants and bud sizing.

Features

This highly soluble formulation has a low salt index and contains no sulfates or harmful chlorides, making it a very safe fertilizer for young transplants to initiate rapid root development. Adequate phosphorus is also required to initiate the stretch and bud formation. When plants are of a sufficient level of maturity or when buds are pea-sized, feeding with 15-30-15 provides a boost of phosphorus to promote vigorous bud setting and sizing.

Recommendations

  • Feed during Week 1 once roots are present to establish a healthy root system
  • Feed during Week 4 to boost bud formation
  • Feed in rotation with Plant-Prod MJ™Cal-Kick as needed

Good quality
Size: Large, Color: (035) Steel / White / Black
These are a bit thicker then a compression sock and they come up higher on the ankle than a no-show sock normally does. They are very comfortable and soft.

Finally found a good set again.
Size: X-Large, Color: (001) Black / Black / Castlerock
I’m picky on socks, any they always have to be Under Amour. These are top notch, super padded but also temperature regulating, feet don’t sweat when wearing, and I can tell in the winter they’ll stay the right temperature. They also fit great. Purchasing more.

Best Quality Socks & Great Thickness Plus Comfort
Size: Medium, Color: (001) Black / Black / Castlerock
I love these. They do not slip away from foot. The value for a good pack of socks was worth it. Has a good thick quality. They look clean and nice. Their stretch is good to get on and then molds to foot. Have noticed these socks have changed two times since buying. First they were slightly lighter color gray- then a darker gray but both had good quality and thickness. I am sure these are very durable but unfortunately I can not speak fully to this as the horrible steel toe shoes I have to wear rip everything apart. But if I had good shoes and everyday use of these I know they would stay good for so much longer than 6months.
