Jane’s Mailbox Pack has the maximum amount of fertilizer in a package that
still fits through your mailbox! This means you do not have to go to the post
office to pick up your order if you aren't home! A bigger package won’t fit
through your mailbox anymore and will be delivered as a parcel.
1x 250g Roots
1x 250g Grow
1x 500g Bloom
1x 500g Boost
When you start growing this selection of fertilizers is the optimum configuration of a package that still fits through your mailbox. You don’t need as much Roots and Grow as you do Bloom and Boost which you roughly need in equal amounts. When eventually one or more fertilizers are finished you have a good idea of your specific usage and can order new fertilizers accordingly.
The Mailbox Pack is, when using it for plants with medium to high nutritional needs with a short to medium long flowering period (8-12 weeks) good for an average of 13 m² (+/- 5m²) of garden. When using it for plants with low nutritional needs it will be much much more!
Because of our fertilizers’ high concentration & buffering qualities you only need to feed your plants once or maximum twice a week. (Measuring of EC-values is not needed because organic nutrient values can’t be measured correctly)
We strongly advice to start feeding only once a week because that is usually enough. Sometimes plants require feeding twice a week, depending on every plants different nutritional needs, plant size, pot size and growing medium. For more feeding advice you can check our Nutrient Schedules in the downloads section.
