ЕNVIRONMENTAL DEVICES - Всичко за вашите растения!
The GSE Water Cycle Timer does exactly what it says on the tin, switching the pump to your hydroponic system on and off as required, allowing you to tailor feeds to your plants' exact needs. Just choose the length of each feed, then select the duration of the 'off' time before feeding commences again - that's it! You can even choose different settings for daytime and night-time - the light sensor will automatically switch the unit to the right schedule!
