Waiting for this master gardener deluxe kit. It should be here in a couple of days. Can't wait. My first grow died at two weeks old due to ag nutrients. I should have known BETTER. It seem like it was working until the secound week of grow when it was time to use the spouting nuts. I've had used 2 like they said. I also change the water. The next day they was dead! Maybe 1 of the nuts could work... MAYBE. You folks could try. I ordered me some hydro nuts from Hydro Empire. They will also be here in a couple of days. I see everybody in here is useing fox farm. Thats cool i will try this in future grows to come. For now i will try : Ionic Boost,Flora Nova Bloom and Flora Nova Grow cant wait YEAHH BOYYYY This master gardener should come with more explaining on time setting also. I'd let you all know.
