I'm resurrecting this thread! I also recently started using Hi-Brix molasses with my GH Flora nutes in a hydro setup.
I grow in the WaterFarm buckets, and they have a 2-gallon reservoir. I have a particular method that works very well....for my setup. Here's my schedule and how I'm using the Molasses during flowering.
- Day 1 of flowering , I change the res and add fresh nutes, I do not introduce the molasses at this time.
- Day 3 or 4 - the plant has drained about 1 gallon of water from the res. I now fill a 1 gallon jug of fresh plain water and apply 2ml ( or about 1/4 teaspoon ) of molasses and shake it up very well. This stuff becomes completely dissolved in the water once you shake it up a little..you cant' just let it sit on the bottom in a lump. I then dump the contents into my res and adjust the PH to 5.9 again if I need to.
- Day 4-7 - top off res with fresh plain water as the plant needs ( the waterfarm buckets have a white line indicating the "full" level ) . Adjust PH as necessary to 5.9
- Day 7 - fresh res change and start cycle over again...repeat until...
- 2 weeks before harvest - which is about when I start to see 10% red hairs ...I will start 'flushing' with 1/4 strength nutes and molasses mixed together at rest change and add the molasses/fresh water mixture to top off the res as needed.
