So...Good comments for my learning. I did alot alot alot of reading over last 2 weeks full time. I had wrong soil ph (8) and no "p" or "k" under soil testing. I corrected a real soil mix after training from horticulturalists at the local places I snooped into for expert soil help. I found out I needed the following:
*3000 Lumens/sqft min. - Was under powered light source at 2000 lum. Now Im at 3400. Lighting results overnight.
*Pots were too small. They wouldn't hold enough water and roots were compressed. Larger pots now 2 gallons.
*Soil was corrected to spec - phwas 8, now 6.5-7.0 Nutrients are testing at midreange strengths. also added epsom salts to increase calcium uptake since plants showed weak calcium intake possibly from deficiency charts.
*Temp was way too hot on lights....twas 100* F at base of hood. I had 2 - 250MH with commercial hoods that fully enclose the light like at a warehouse or grocery store..see pic. Full deep round hoods that send light down with a 45* range see pics. I think these were a bad shape and made hot spots that burned as well. I had to keep lights far away (3'); loosing more power. I bought a 1000Watt MH switchable for the new 5x5 room I'm hooking up this week. I will also keep as flowering room and switch to HPS in a few weeks. check.
*Ventilation...I had no ventilation and now do. 4" dryer vent intake and 3" pipe hooked up to a bathroom blower fan exhausting right into the chimeny exhuast leading to the rooftop.
*Moisture control...I was fumbling keeping moisture in balance and had........anyway. I fully wrapped a room 5x5 with plastic and sealed it completely even at the door with foam seal. Moisture now stays at 40-55% with no help...simply evaporation from plants maintains balance.
I needed a good boost since first crop. Thanks to all who promote the "sport" with open arms. -few states legalized...more to go-:icon_smile:
