Oh so your in the club. BPN is definitely the best to use for growing any plant. Hydro grows even better. I didnt know those were hydro. How are those set up or whats in the 2L? Do you have air running threw there?
I'm running Hempy Pots. It's a passive hydroponic method. My mix is close to 75% perlite and 25% vermiculite. No air involved.
I'm using the The high yield feeding schedule with all BPN's 3-part line up; Grow, Micro, Bloom, Vita Blue, Liquid Seaweed, Early Bloomer, Liquid Blue, Root Magic, and also their PH Down.
I was running low on Bloom so those A Trains weren't getting a full dose with every feeding. FedEx solved that with a delivery today.
Vita blue and liquid seaweed is like crack to plants lol.
I may have to try that hempy grow style as a side show. I'd like to see how they work. Sounds fairly easy. I run a RCDWC system. Works very well. Easy no managing needed.
Seriously, check out some of 420fied's grow journals. Seeing is believing. Google "hempy pot".
The Hempy Pot technique is as simple as it gets for hydro. Coupled with Corey's knowledge at Blue Planet Nutes, a person has t be daft to not come up with "decent" results.
Only down side to the technique is hand watering every day. Sounds fine at first, but it becomes a hassle.
