It’s springtime here at ZKsciences and we couldn’t be happier to get planting!

We’d like to see how our ZKBoost plant growth enhancer does with your plants where you are! We want to see how ZKBoost helps you further your flowers, boost your blooms and vamp up your vegetables. So we’re announcing another contest for this season!

We’ll be picking the most impressive container plant grown with our ZKBoost plant growth enhancer over the 2023 growing season, and making a donation to the charity of that gardener’s choice. We’ll automatically enroll everyone who makes a ZKBoost purchase from the ZKsciences website – https://www.zksciences.com/store – and we’re offering 23% off ZKBoost for a limited time in celebration of spring. Just use the coupon code ZKSPRING2023 for your discount. That’s in addition to free shipping in the continental US and reduced price shipping to the rest of the US and to Canada for a limited time.

Make sure to send your ZKBoost plant photos and a description of the best plants you grow to hello@zksciences.com to be eligible for our growing season contest. We’ll be choosing one lucky winner from the photos and updates we receive on September 15th, 2023.

Keep checking back here or follow ZKsciences on Facebook, Twitter or LinkedIn for contest reminders and other news over the course of the 2023 growing season.

Thanks and happy planting with ZKBoost!
