Grow Diary — Josh lavelle

1 comment by Krystal Zheng

Recently, WEEGrow is honored to receive plant grow diaries from Josh Lavelle. In his diary, Josh recorded how WEEGrow QB-2000 LED grow light assisted the healthy growth of Red Hot Cookies, C99, Nebula, and Chemdawg in the tent. So why QB-2000 plant light can stand out among other plant light brands? 

The answer is that WEEGrow QB-2000 best lights for growing plants which adopts Samsung LM301B diodes as its full-spectrum plant-specific lamp beads and MEAN WELL as its standard power driver, providing the required light to all growth stages of plants on the premise of a high-quality power driver. 

Compared with other brands of plant lights, QB-2000 plant lights are superior in accelerating the healthy growth of plants. In terms of heat dissipation, WEEGrow uses an aluminum plate as the backplate of the plant light, which speeds up the dissipation of heat and keeps providing light for the plants in a low-temperature environment. 

Stage one:

Tips for stage one:

During this period, you need to always pay attention to several necessary conditions for seed germination:

  1. Suitable temperature: Under normal circumstances, the temperature around 15 °— 30 °C is easier for catalyzing the enzymes from the seed.
  2. Sufficient water: Only when the water content of seeds reaches 50%, can they transport nutrients, thereby promoting the catalysis of enzymes.
  3. The oxygen: The oxygen can provide energy to the seeds, so as to use these energies to transport nutrients, promoting the germination of seeds.
  4. Light (if needed): Generally, light has little implication for light seed germination, because most of the seeds can proceed in dark or light conditions, But there are a few seeds of plants that need to be lighted to germinate.

Week 1 (Day 1-Day 7):

Soak the seeds in water with KLN concentrate and 3% hydrogen peroxide H2O2 for around 20 hours, then soak on PP. RHCs appeared first on the 12th and the rest appeared in the next couple of days.

Stage two:

Tips for stage two:

Watering: When watering, you should make a plan grounded by the different requirements of plants for water, watering amount, watering time, and watering method.

Light: The requirement of light that the plants need is formed by the surrounding environment. So if you want to grow a plant indoors, you need to square the illuminating time with the light amount that plants need.

Scarification: Soil loosing can ensure the normal respiration of plant roots and improve soil porosity.

Ventilation: Keeping indoor plants ventilated. Ventilation should generally be carried out from 9 am to 3 pm.

Week 2 (Day 8-Day 14): The plants were transferred to 2L pots.

    excellent grow, congrats. What size tent and how many of the WEEGrow QB-2000 LED fixtures are you using in this tent? I have a 3×5 tent with two of the WG-1000, plants did good. Looking to set up another tent is why I’m asking.

    Thank you
