I've seen many people in the hydroponics shop asking about PH up/downs. Thought I'd share simple household products that do the same thing.

If on a grocery run, you can also grab some pH up or pH down from the pet aisle. They’re sold with the aquatic pet supplies.

How to do "LST" on Autoflowering Plants ?
Hello dear growdiaries community, so on my last question people recommended NOT to use "Topping" for Automatic Strains but infact only use "LST" my question would be how that works, do i just bend down the leaves with the little things on the stem (marked on picture) 😂 thanks.

Ideal temp and humidity for autoflower strains.
Based on what I have researched, it looks like photosensitive and auto strains require different parameters. Is that true? Is 75°-85°F ideal? Is 40%-70%RH ideal?

12/12 with autos in flower?
I’ve never grown autos so I’m looking for some advice.. Is it better switch your lights to 12/12 when the plant goes into flower? I feel like in theory this would make sense for THC development. Thank you

Does the size of container /indoor plastic in Coco coir make a difference in flowering?
I am experimenting with flowering in 1 gallon plastic containers. Coco coir as the Medium. Feeding twice a day min. So far the plants are looking great for 2 weeks into flowering using this method. My last grow was in 7 gallon fabric pots. Rootball was no bigger than 1 gallon.

Too fast, too high
So here's the question. The box height is 1.5M. plant is already 75cm + pot size. Apollo-1 is getting closer and closer to the lights, which I don't like. It has 35-40cm left till light panel. Do you recommend to super crop the center, main stem?Or do you have any other solution?

Coco coir feeding and watering techniques
Can I water much more often when using canna's coco coir and perlite? I read somewhere about people watering twice a day in 7 gallon vivosun fabric pots. Plants have been begging for nutrients. I was watering once every 3 or 4 days. Can I water them every day?

Can you put your plants into veg after one day of 12/12??
I accidentally left the timer on 12/12 in one of my tents I was supposed to flick it onto 18/6, If I revert it back to 18/16 quick after only one day of 12/12 will this do anything or just slow the veg process down?

SilverSol vs Colloidal Silver 4 Feminization Of Autos?
Question: are there any differences in structured silver solutions like SilverSol "SS" vs regular silver like Colloidal Silver "CS" for feminization? Both are interchangeable for most purposes. It seems SS has more active ions, would that be a bonus? They said SS 10ppm = CS 50ppm
