I am in week 7 (seeds germinated 47 days ago and sprouted 44 days ago) for growing 6 auto flowers- 2 Northern Lights, 2 Amnesia Haze and 2 Blueberry- all 6 seeds sprouted! They seem to be doing OK but I have pictures attached for better community judgement. My questions are mainly due to conflicting advice and opinions on some important topics. I’ll do the questions first and then provide my specifics as to what I’m using:
I have been doing 20/4 since seedlings. I keep hearing that plants need art least 6 hours of darkness to properly grow. OTOH, there’s the opinion that you can never have autoflowers get too much loght (short of the fixture burning them). Who is correct? And, related, if I can do full-spectrum with my fixture while maintaining good airflow/temp/humidity, should I, or should I just use the red cycle?
How much water, really? So far, I’ve been watering every 2 days. Using FFOF and grew from the seedling straight into my final growing medium of 11 liter pots, but did create a depression the size of a 5’ planter to use Black Gold seedling soil so that the seedlings wouldn’t grow straight into the too "hot " for seedlings FFOF. I have been doing so far so good with watering gradually; they’re now up to 1 liter of water or so each every two days. Other advice is that I should be watering to 10% runoff every day. Who is correct?
Grooming- I haven’t done any removing (except for two damaged leaves) to open up the plant space to get more room to the bud sites. I’m still at late veg/early flower, depending on the plants. The Amnesia Haze ones are barely beginning to flower but I’d expect that’s normal given they’re sativa and take a while longer to develop. As this was my first autoflower grow I only did LST on one plant, just to see the results. It did seem to create more bud sites. Should I be taking any leaves now? I understand overgrooming is not recommended, but other growers seem to swear by the results, so I’m at a loss of what I should do (if anything) and when.
I’m doing 6 plants in a 24"X 48" X 84" Gorilla tent with decent ventilation and lights. Is that too many plants for the tent size? Would I really benefit from removing a couple and letting ambient/flourescent light take care of those, hope for the best, and get a better yield with the remainders?
Thanks all for the help.
-24" X 48" X 84" Gorilla Grow tent
-AgroLED Dio Watt 720 low pro with veg and bloom switches; consumes 450 watts to produce 720W from 240 led lights, full spectrum.
-FFOF soil with Black Gold for seedlings, water filtered and Ph’ed to 6.2-6.5 (though I am getting some lower runoff, so may need to adjust)
-6" 65 -watt 3-speed exhaust fan with carbon filter
Thanks so much and please see attached photos of girls and setup:Blueberry 2 (lost picture of #1), and exhaust fan, light set up, and interior of tent from side and above.
