I started feeding liquid nutrients this week. Although I鈥檓 using Nature鈥檚 Living Soil Super Soil Autoflower Concentrate mixed with Fox Farm Ocean Forest鈥攕o technically I could water only until harvest鈥擨 decided to begin liquid feeding in Week 3 at half the recommended dose.
I also have a Tray2Grow Autopot system for automatic bottom feeding, but I haven鈥檛 activated it yet. When using liquid nutrients via top feeding, I鈥檇 need to turn the Autopot system off and wait until the plants absorb all the water in the tray before feeding from the top. Afterward, I鈥檇 have to manually turn the system back on. That seems like a hassle compared to just hand-watering and feeding.
I could technically add the liquid nutrients to the Autopot reservoir, but that somewhat defeats the purpose of the system. The tank holds 25 gallons鈥攅nough to last a few weeks鈥攂ut if I want to change or rotate nutrients weekly, I鈥檇 have to dump the remaining water and remix the solution each time. If I wanted to feed nutrients every other watering, I鈥檇 be changing out the tank every 3 days. Plus, liquid nutrients can cause buildup, so I鈥檇 need to clean the reservoir and all the tubing regularly.
For now, I鈥檒l stick with hand-watering and top feeding. I鈥檒l only switch to the Autopot system if I need to leave town.
