Best on the market
I've used all the rest and this one is the BEST. Not only is it a good price but it really works and plants thrive and mature to healthy plants. This combo pack is the best price I've found and only have to order twice a year. If you plan your growing out and not waste the product and reuse what is left in the plant containers you can grow about 2800lbs of food off this combo pack. That is tomatoes, peppers, cucumbers, lettuce, squash, zucchini, 5 types of herbs and strawberries, cantaloupe and beets and radishes. Everything you need to succeed so go be happy urban farmers and grow healthy.
