Space: 3x3x5 Closet lines with foil (temp till 79x79x79 tentarrives)
Lights: 1. 8 Bulb T-5 fixture running 8, 24watt 6500k bulbsfor a total of: 192 watts with an output of 92.58 lumes per watt for a total of 17775.36 lumes/9 sq ft = 1,975 lumes per sq ft. My target was 2000 lumes per sq ft. so I’m a bit under right now.
Containers: 6.5” potsto start with.
Soil: Fox Farms Ocean Forest, Perlite, Sphagum moss, in a4/4/2 ratio. Water storing crystals ¾ tsp mixed into soil. Great White Mycorrhize mixed into soil.
Ventilation: 12” oscillating fan
Humidity Control: cool mist vaporizer maintains 50% night, 60%daytime
Soil pH: 5.8 after pulling a sample of soil, watering withdistilled water(water pH was 6.25)and let it soak overnight. Using a Hannadigital pH meter calibrated every month.
Water: Tap at 200 ppm out of faucet, pH’d to 6.55 and rechecked after sitting overnight. I understand the pH level can vary according to water temperature, but so far my plain tap water is stable after sitting overnight.
Nutrients: Heavy 16 Veg A & B. Heavy 16 Prime, Heavy 16 Foliar. Right now I am letting the FFOF provide nutrients for the 3-4 weeks, and then I plan to start at ¼ recommended dose feeding.
Sprays: SM-90 sprayed every 3rd day. Smells great, but I’m not sure I need it.
I germinated 9 of 9 THC Snow Feminized seeds and plantedthem direct into my 6.5” containers. I understand now that planting into a smaller container might have been a better idea, but so far it seems it be working out.
My seeds broke soil on 3/5-3/9 and 6 seem real strong, with3 other lagging behind. I am watering asneeded to keep the soil moist, but not soaking wet. My pots are sitting in a water heater overflow pan with spacers under each pot to hold them up out of any runoff from watering. I started out with my lights 16” above the tops of the seedlings. I am not sure if my seeds were stretching to reach the light, so I slowly started to lower my lights over the past few days watching for heat stress. Today I am within 4” of the top of my tallest plants.I think I will have an issue with my lights being so close because I have some Bubble gum seedlings just sprouting.
My main issue right now is ventilation in my closet. Inorder to try to provide some sort of fresh air with Co2 in it I open the door afew times a day. I plan on adding a C02 tank, monitor and regulator after mytent arrives. My fan is blowing on the plants and I have had to add someadditional soil as backfill to provide support.
I have a few questions for folks that have more experiencethan me: 1. How high can I add soil for backfill around the stems, or is this ano, no at this point in their young lives? 2. The directions on the Heavy 16nutrients say my additives should be no more than 33% of the total TDS and thatadditives are anything except main nutrients (Veg A & . This is confusing to me because I thought Iwould be using my nutrients to adjust the TDS. I had planned on stepping up myTDS weekly after I started my feeding schedule. 3. Am I getting my lights too close for such young plants, even thoughthey do not appear to show any heat stress? 4. What CFM rating for an exhaustfan would be appropriate for a 79x79x79 tent? I don’t think I need one thatwould move my entire 274 sq ft out in one minute. 5. Would a 4” inline fan witha HEPA filter be more beneficial as a fresh air intake or should I just use thevents built into the tent? I live in avery dry and dusty area and I’m worried about what the dust might bring intothe grow tent.
Please feel free to add comments or advise. Thanks forlooking.
