Thought this would be a good place to post this tip, if I am wrong please move to an appropriate spot. As a new grower having more than one plant I have a difficult time keeping track of feeding/ watering schedule. I will not do any type of log, so I came up with this , a 3X5 waterproof card laminated with three sections FEED,WATER,WATER. I use a china marker to note the date of feed/water and amount. I use the back of the card to note other details such as measurements.I use a small piece of solid 12 gauge wire to form a hanger as shown. The 3X5 card should be waterproof for durability, these little things will last a long time. I believe I purchased the cards from Amazon. Good luck.
