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 CorianderCoriander or cilantro as some people know it, is a very popular herb. Coriander is a versatile herb with its seeds being used as a spice and the plant itself being used as a herb.Sticking with its use as a herb, coriander is described as having a mellow even subtle taste profile, slightly tart tasting with lemony/lime edge. Really quite different in taste to the seeds. Much like basil heating the leaves diminishes their flavour rapidly, so it is best added just before serving the meal coriander loses it’s flavour rapidly with time after being picked or stored in any way, making having a Hydro-herb kit in your kitchen ready to go all year round a very attractive option. 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.
