Questions

Do I need all of these products?
No. To start you need a tower, nutrient, a meter and pH down. Everything else depends on whether you grow indoors, outdoors or tall plants like tomatoes.
Which meter should I buy first?
The budget Pious meter is enough to start. If you measure often, the Bluelab OnePen is more convenient. The Guardian is for anyone who wants values on the phone around the clock.
Why are there prices on this page?
The prices come directly from Amazon and update automatically. The date below each block shows when they were last checked.
