Light is definitely one of the most important factors during their growth, but darkness also indispensable for plants, like human, they also need rest. During the day, plants absorbed the light for photosynthesis to produce energy. At night, plants will break the energy down for growth and flowering.

DWC know as Deep Water Culture, as the name implies, it is growing plants with roots in aerated nutrient water. Plants growing with DWC can make the plants grow faster during vegetative stage.

It’s time to transplant the plants when they have passed the seedling stage and are beginning to enter the vegetative phase of the grow cycle.

Usually when the plants need watering much more frequently than it usually does. It will also probably start to display symptoms,such as completely stunted growth. The leaves may begin to turn yellow and wilt.

With the blooming of indoor growing, more and more lamps come to the market, HPS, HID, LED etc. So what lamps we should choose.

Some people would like the HPS, why? Because HPS are cheaper than LED, and can also grow some dense buds. But we have to admitted that HPS will cost more energy and generate more heat during working.

Dear all Mars-hydro customer:

We decided that we will stop producing Mars II series grow lights now,after all the stocks sold out,the Mars II series will be history.

We have been selling Mars II series light since 2011,then we upgraded the light: daisy chain,chips from 3W to 5W,growth and bloom switches,later we had passed the ETL certification...

2 Transplant will help to prevent root-bound
