Decent products, room for improvement

I bought the Grow Your Own Kit and a bottle of Sticky Fingers Resin Enhancer. The kit itself is a great starter pack, very comprehensive for someone new to growing. The Sticky Fingers worked as advertised, I saw a noticeable difference in stickiness on my recent harvest. My main critique would be the website's FAQ section; I had to search a bit to find specific info on shelf life. Delivery took about a week and a half to my address in Michigan, which was a bit longer than I hoped, especially for the price of shipping. The packaging was secure, no leaks, which is a big plus for liquid nutrients.

Good kit, slow shipping

I ordered the Autoflower Nutrient Kit and it seems like a solid product. The instructions for the feeding schedule were clear. However, shipping took 8 days to reach my place in California, which felt a bit long. Everything arrived well-packaged though.

Quick shipping, great results

I ordered the Bonnie and Clyde Autoflower Base last week. It got here in just 3 days which was way faster than I expected for standard shipping. My plants are already looking super happy with the new nutrients. I'll probably grab more when I cycle through this batch.

My plants love this!

Got some Bud Booster and my plants are looking awesome! Seriously, way greener and the buds are getting huge. Shipping was super quick too, like 4 days. Definitely happy with how my harvest is shaping up.

Reliable and consistent nutrients

I've been using Cronk Nutrients for a while now, primarily the Classic 3-Part Series. This recent order was for more Bloom Nutrients. I appreciate the consistency; I always get good results with their products. Shipping was on par with previous orders, about a week to my location. I had a quick question about a feeding chart years ago and customer service was helpful then too. It's why I keep coming back, can't argue with consistent quality.

Thinking of trying Cronk. What's good for a first timer?

Get the Autoflower Nutrient Kit if you're doing autos. It's pretty foolproof.

Do I need CalMag with Cronk?

W WaterWizard 1 month ago ✓ Best Answer
Depends on your water and medium. If you're using RO water or coco, usually yes.

B BrandLoyalist 1 month ago
Cronk sells their own CalMag, so they probably expect you to use it.

I always add a little CalMag just to be safe.

Cronk PuurOrganic line vs Classic 3-Part, which one?

O OrganicOllie 2 months ago ✓ Best Answer
PuurOrganic if you want to stay truly organic. Classic 3-Part if you're fine with synthetics and want max yield.

Is PuurOrganic OMRI certified though?
