Growing hydroponically means there's no mess and as the growth fluid is clearly visible in the lower part of the bottle it's very hard to run out without you noticing. There is enough fluid in the pack for at least a year's growth! About Flat ParsleyProving to be possibly our most asked for addition to the family, despite the presence of its Curly leaved brethren is Flat Parsley, clearly a fresh herb that is enjoyed by a very large number of people. Parsley is in the wild seen to show a two year growth cycle with it growing leafy in the first year ( roughly 30cm max height) and in the second showing a flowering stem (easy to identify due to it looking quite different and outgrowing its surrounding stems) , indoors it will grow all year round and if you nip out the flowering stem as it appears in the second year strong vegetative growth should follow.Commonly used as a garnish on meals just like curly parsley, flat parsley is also often seen as part of a bouquet garni used in the preparation of stocks, sauces and soups. Unlike other herbs cooking with parsley does not reduce its flavour profile, in fact it is enhanced by this process allowing its slightly bitter peppery tones to shine through. Comes with instructions! :) DESIGNED WITH THE ENVIRONMENT IN MIND We have done our absolute best to ensure that the Hydro-herb kits we sell are as environmentally sound as we can make them. We source our parts carefully trying to ensure that we have as small a carbon footprint as we can. All of the parts in our kit are either recycled and recyclable or entirely biodegradable. The wine bottles that form the largest part of our kit are obviously reused rather than recycled locally minimizing any carbon production from melting the glass down or transport. We use capillary matting that is recycled and the plastic bottles in our kit are also made from recycled plastic that may itself be recycled. The Jiffy Pellets that we use are made of coir (ground coconut husk) rather than peat so that we are not contributing to the reduction of peat bogs. The cork lid/placemat comes from renewable sources in Europe as do the natural rubber band. The terracotta pebbles used in the kit along with the cork and natural rubber band are all biodegradable.
