What is your biggest question about growing cannabis?

I just switched two 8 w GDPs to 12/12 and the stretch in the first week is quite a bit. Defoliated them quite a bit too as they were really bushy. I fimmed them both early on so they are pretty gangly now and would be easy to manipulate. I made sure they have plenty Ca and N going into flower but then back off completely.

Hi all, im growing a single Grand Daddy Purple which is just about a pure Indica, its in its 4th. week of veg. Its a very bushy plant, I was wondering when I should switch over to the 12/12 flower cycle. I still want to weave the branches in and out of the.scrog net which I haven’t done yet, can do this after switching to 12/12, or keep it in the veg. state while spreading out the branches in the scrog net. Thanks.

There is a veg cycle called 12/1. It is 12 hours light, 5.5 hours dark, 1 hour light, 5.5 hours dark, repeat. This keeps them in veg, while saving on electric cost. I believe it was developed to confuse LEO when looking at power usage. If this keeps them in veg I think 1 on and 1 off would do the same. They need 12 continuous hours of dark to switch to bloom. If they were already in bloom, re-veg.

I have my doubts about that one. I think the plants need time to switch chlorophyll production on and off. I would liken it to sleep.

12 hr light period. I wonder how a plant would react to 1 hr on 1 hr off over 24 hrs for the flowering period?

I use a 50 w LED as a heat booster. It cycles at 82F. But the part of the plant closest to it always seems to do better. Maybe it's just the added light?

I've got some FFOF and next time I use it I'll cut it at least 33% with perlite and add generous amounts of limestone. Happy Frog would be half that.

FFOF says their soil is 6.2 to 6.8 which is bearable. I am going to test the runoff tonight.

[3Berries]

Those stick in the dirt combo meters are junk. Good for the moisture and light maybe.

I've found FFOF to be quite hot. I'm using some now and it locked out my K & N. Using wood ash to combat the issue.

I have an Apera pH meter and water to run off to get a good enough sample to test pH when I want to see what's up. I also test the ppm of the run off.

I have this disability called "essential tremor", maybe one of you all have it as well, the thing is it is hard for me to taken clear pictures when I hold a device to do it. My problem is ph, or whether to trust the testers I have. For starters I know that my tap water is pretty balanced because I had tropical fish and tested my water on a regular so historically our water here is very good. I have 2 of those stick in the soil meters and they don't really react when stuck in the pots, and they don't react when stuck in hot soil. When I say not reacting I mean the needle stays on the acidic end or as in not moving. Am I wrong in assuming the soil I used is balanced? If the FFOF and super soil are balanced shouldn't my tests say so. I don't have any faith in those testers, I have 2 that are the same, and the moist test is OK, but I don't like the light test too tough, I had to almost touch the 120w "full spectrum" led to bury the meter. If my plants are looking good maybe I am stressing myself over nothing. Its hard when there is little to do by water and get a trellis ready.
My plants 6 GSC and 1 mystery seed are at 4 wks on Friday.

Rcass did you read that link? I'm not a hydro grower.

Hi folks,

I can give all the specs if needed but for the moment my biggest question is “has anybody encountered seedlings with yellow veins (see pic) and basically no growth. If so what was the cause(s)?”

[Puglover1]

Last year in summer I filled empty quart Powerade bottles with water, froze several, put them near oscillating fans or just set them around in my closet, the floor has a thick plastic sheet over the carpeting. I had extras ready if the water melted, just switched them out. It helped the temps stay around 80F to the lower 80's.

[3Berries]

Make sure the humidity is where it should be, in the mid 70% at that temps. The more moisture in the air the more heat it can hold.
