N-Ext Sea-K™ is known in the professional applicator community as "microbe food," this special bio-stimulant is your secret weapon in jump-starting even the most tired soils or stressed lawns. 

  • 1 Quart covers up to 64,000 sq ft
  • Analysis is 0-0-5::N-P-K
  • Benefits include - deeper color, increased rooting, pest resistance, drought protection, increased nutrient uptake, and reduced senescence
  • Safe for use on all turf types and ornamental plants

Product Description: 

Sea-K contains a highly concentrated Sea Kelp derived from the cold waters of the North Atlantic, as well as high concentrations of Auxins, Gibberellins, and Cytokinins. These, combined with the naturally occurring trace elements and minerals, will give an added boost to your fertility program.

For those on a budget, this can become your go-to bio-stimulant since you can use the low rate of 1/2 oz per 1,000 sq ft monthly to stimulate healthy soil, rooting, and rhizome activity. Sylvestor Stolons approved! In addition, this small quart bottle can be stretched up to 64,000 sq ft (see application rates below).

You can SAVE MONEY with our "mix and match" Build-a-Box option

Application Information:

**We highly recommend you apply Sea-K with precision from a pump/battery hand can sprayer and water it in after application with at least 1/4" of irrigation or rain.

It can be applied with a quart hose-end sprayer bottle, too, but since this is concentrated and more expensive, it's better to control it with a pump/battery sprayer. We don't want you to waste this precious bio-stimulant.  Here is a video with hose-end sprayer instructions.

You could start out with the higher rate on your first application, then go to the lower rate for the remainder of the season and be in very good shape. 

Sea-K can be used on all grass types, including the following:

  • Cool-Season Lawns - Kentucky Bluegrass, Turf Type Tall Fescue (all fescues), Ryegrass.
  • Warm-Season Lawns - Bermuda, St Augustine, Zoysia, Centipede, Bahia.
 Coverage

64,000 sq ft at the low rate (1/2 oz/1,000 sq ft)

32,000 sq ft at the higher rate (1 oz/1,000 sq ft)

Aggressive chewer who loves fetch approved!!
Size: Medium, Size: Medium
I highly recommend the Chuck-It brand in general, especially for dogs with an aggressive bite. These balls are awesome and are the most durable balls I’ve bought for my 50 lbs lab mix. He has not been able to break one of them yet and we’ve had a few of the squeaky balls for months. They are a bit pricey but worth it. The one in the pic has been used for months, lives outside and you can see it’s still in great shape.

Good quality dog ball for playing fetch
Size: Medium
My dog and family love these chuck it balls to play fetch with our dog. They are durable and fun. They squeak which is added fun for any dog! Regular tennis balls my dog chews apart and they get pretty gross after playing and being left outside. These can be easily washed off and cleaned. These balls last! Would recommend to anyone with a dog and would purchase again.

One Tough Ball!
Color: Blue
Our dogs are loving this ball. Our 1 yr old hound is a world-class chewer and he can't make a dent in this ball. The interactive buzzing and bouncing keeps them entertained for long durations. It's a mite noisy but the barking from the 1 yr old is much louder, lol. Even turned off, they like playing with it and chewing on it. Based on the tough construction, we think it will last much longer than traditional chew balls.
