There a numerous plant enhancing supplements being marketed to growers, suggesting that the supplement Is essential to obtain maximum dry matter yield, high quality flowers and fruit, or ensuring optimum plant nutritional status. For the grower when selecting a designated growth enhancing product, he should obtain a data sheet on the product that includes: name…
Are these two correlated? Yes. since the nutrient element status of a plant is affected by how the plant is being grown, and elemental status is related to photosynthetic rate. Hydroponics offers the grower better control of the plant’s elemental status than most other growing procedures. But, photosynthesis rate is also determined by light intensity,…
The one aspect of hydroponic growing that is not being utilized today is outdoor growing either in the home garden or community gardens. This probably is so since most hydroponic growing methods are not designed for outdoor use and require expensive sensitive operating components, growing systems, using hydroponic methods such as flood-and-drain, NFT, and drip…

Rockwool cubes are used for seed germination, and rockwool blocks and slabs as a rooting medium for growing plants hydroponically. Rockwool is marketed as a rooting medium primarily based on its water-holding capacity and aeration characteristics, rather than its elemental content. The total elemental content of rockwool (decreasing range in %): Fe (10.5-13.4), Ca (7.30-11.8),…
