First Grow, Bubblegum Auto

Good luck with your plant. I wouldn't perform misting twice a day. Once a day is way enough in my opinion. Too much humidity is bad for diseases, bugs...

Beautiful, you did an amazing job! 👍😎

If you grow a photoperiod strain, look into LST and ScrOG, the two go together really well. I completely fill out a 2ft x 2ft tent with two plants using these methods, and get about 3 to 4 ounces dried! For about 6 weeks worth of veg (I've done some experimenting and cloning and stuff lately though, hadn't popped a seed in many many months)

Looking good for a first timer! You clearly did your homework, good luck my friend! 👍🤙

When can Bubble Gum Autoflower and I run away toghether into the horizon?

Nice grow mate, plants are looking good, keep it up, imma follow this one upclose.

Grow Room The grow room is made from ¾” Schedule 40 PVC Pipe frame. Corrugated cardboard boxes lined with black duct tape on the outside and Vivosun Horticulture Highly Reflective Mylar Film (Roll 4’ X 50’ 2 Mil for $32) inside adhered to the cardboard with two-sided carpet tape. The cardboard panels were mounted to the frame using wire ties. Reflective mylar was also placed on the floor of the room. There are two shower curtains hung from the front with a white shower curtain facing inside and a black shower curtain to the outside. The white shower curtain should reflect some light back into the room with the black shower curtain absorbing any light getting through the white curtain. It is literally PVC pipe, cardboard, duct tape, wire ties, and a couple shower curtains. Since the room is in a dark unfinished basement it is open at the top (about 1 ft head space to ceiling). This should allow for adequate ventilation without the need for separate exhaust. See the Air/ Temperature Control section. The room is 4’ x 6’ but can be easily expanded with little investment. The room cost about $70 to build. It can be expanded to 12’ x 4’ for an additional $20. Moisture Control and Watering Humidity in the room is controlled by a Vremi 3,000 Sq. Ft. Dehumidifier ($280) for the 700 Sq. Ft basement where the grow area is located. The dehumidifier sits just outside the grow room. A Moistenland Automatic Drip Irrigation System ($48) is fed directly from the dehumidifier reservoir. Both duration and interval of watering is controlled. The ¼” dripper line feeds through the wall of the grow room. The moisture collected out of the air is used to automatically water the plants. No other water source is used. The water from the dehumidifier is about 6.1 pH with 65 ppm total dissolved solids (before nutrients). Nutrients are added directly to the dehumidifier reservoir each week as required. The dehumidifier is thoroughly cleaned and sanitized between each grow… including the filters. See Air/ Temperature Control for how mold and bacteria are controlled. Air/ Temperature Control The grow area is in a 700 sq ft unfinished basement. The home HVAC system is also in this space. The temperature remains consistent between 70 and 75 deg F. (21-24 deg C.) outside the grow room. Inside the grow room remains between 70 to 80 deg F (21-27 deg C.) depending on the time of day and whether the lights are running. There is about a 10-degree difference between lights on and lights off. There is no need for extra temperature controls. There is a Pure Enrichment PureZone Air Purifier - True HEPA Filter ($100) with a 3-stage filter that includes activated charcoal to reduce odors. The filter is rated for 200 sq ft so it should be enough for the 24 sq ft in the grow room. The air purifier is placed on the floor. It brings in air from the grow room blowing the filtered air up from the top of the unit. The fan in the purifier is set on high and expected to be the only thing needed to move air, eliminate mold and bacteria, and provide odor control in the room. The air purification filter is changed out for each grow. Again, the top of the grow room is open, so ventilation should not be a problem. I have a coffee can with hole punch in the lid Ona Gel Pro inside to help control odor along with a Earth Care Janitorial and Industrial Odor remover hung inside the room. Lighting The 6’ x 4’ grow room has 2 WHOSLED LED 1200W (230w actual) Dual Switch Dual Chip Plant Lamps ($110 ea) attached to floor joists above the room with a rope. They have blue, red, and full spectrum settings. They can be easily adjusted for height. There are also 2 Relassy 200w (45w actual) Full Spectrum Grow Lamp, Dual Head Gooseneck Plant Lights ($30 ea) used to direct light as needed under the plant canopy. All lights are connected to a timer. Light cycle matches natural day/ night cycle. Soil and Planting The first grow with this setup is 3 autoflower plants (Bubblegum, Jack Herer, and OG Kush). A 6’ x 4’ grow room should be plenty of room for 3 plants. They are planted in JERIA 7 Gallon, Plant Grow Bags (12 for $26) with Hydrofarm 14” plant saucers (10 for $41) under them. The soil is a 50/50 mix of Miracle Grow Potting Soil and Miracle Grow Garden Soil. About 2 oz of Summit Mosquito Bits - Quick Kill (30 oz for $17) was incorporated into the top 3 inches of soil in each grow bag. This should control gnats and other soilborne insects. Plants were started in rapid rooter and seedling trays for the first 10 days before being transplanted directly to the 7 gallon grow bags. Monitoring Grow Conditions There are several parameters being monitored during the grow. Soil moisture and light are measured using a Kensizer Soil Tester ($14). The soil mixture used is known to have a 6.5 pH so the water pH is monitored using a Vivosun High Accuracy Pen Type pH Meter ($10). A General Hydroponics pH test kit ($23 includes pH Up and pH Down) is also used for the water pH to ensure accuracy. A Vivosun TDS sensor ($10) is also used on the water. Temperature and humidity inside the grow room are monitored using a Govee Indoor Temperature Humidity Sensor with Bluetooth ($13). Nutrients The watering schedule is about 12 oz per day per plant. It will fluctuate between 10 and 15 oz per day depending on soil moisture measurements. For 3 plants that comes out to about 2 gallons per week. Since the fresh soil mixture already has nutrients, the liquid nutrients are added directly to the dehumidifier reservoir once per week at about ¼ recommended strength. Fox Farm Big Bloom, Grow Big, and Tiger Bloom are used per the ratios recommended for growth stage. Used the Fox Farm Feeding Schedule as a guide (1/4 of recommended amount). Overall Comments There should be good control on grow room temperature and humidity. There is probably enough light for a grow room twice the size… or twice the plants using about 2800w LED total (600w actual usage). Light leaks are naturally controlled by being in a basement room with no windows and light schedule follows actual day/ night hours (the first grow is all autoflower anyway). The air in the room is purified with good ventilation. Watering is fully automatic with proper pH water and nutrients are added per schedule. The soil is the proper pH starting out in is protected against insects. Grow room temperature and humidity is continuously monitored and charted via Bluetooth. Soil moisture is monitored daily and controlled through automated dripper settings. Light intensity is monitored and controlled via adjustable lighting. Water pH is measured daily using a probe and titrated weekly to verify accuracy. Total dissolved solids in the water with nutrients is measured daily. The grow journals for each plant can be found here.
