Hydrogurd does not harm ur plant all it does is prevent root rot if ur water temp is higher then 72 I would add it like 7 to 10 ml

Definitely need hydroguard with temps that high. At 2ml per gallon that ends up being 5ML which is what I add. It’s closer to 2.5 gallons in the res than 3.

My temps stay at about 70-71f and roots have been good from day one. All I’ve been putting in at each water change is 2ml and my roots have never looked better.

Thats why a little goes a long way with Hydroguard. I’ve never used more than 2ml for each water change. I dont think you need 5ml or more. Start at 2ml for a few several water changes and see how they look/develop.

My water temps are around 80 degrees. I started a half teaspoon with my third refill. First day early veg. The nutrients dispersed at this stage. I’ve been been following these root rot topics. I feel happy to know it works and thank all the people who invest in helping us. Thank you

I have not been able to get my bottle 1,2,3and 4 to fire after drain and fill, number 5 fires off right away though!

Hayden, i was told buy Todd that the nutrients despense differently depending on the strain and type of water you use. If you’re worried, do ph check to see if they are working properly. Or you could always put in a ticket with support. I had the same issue espically in the early stages.

my 3 and 4 ended up dispensing later on after the fill I had my drain hose sprout a leak yesterday and had the side off my unit to check and make sure all my connections were secure on the board for my nutrient pumps we should be good to go now. Fingers crossed, thank you for sharing about your experience.
Happy growing

So here is my baby on Day 20 10/14 early veg, should I add a week or 2 to her early veg or will she get bigger throughout transition, Todd told me it really doesn’t matter whether you add time or not since its a auto just would like to hear some others input as well!!

Hayden, I don’t have any personal experience with Autos. I would not choose to grow them myself due to how they’re designed.
As I understand Autos don’t always respond well to techniques photoperiods do. As such it is suggested to tuck leaves rather than cut.
We have seen examples of autos topped, trimmed and lollipopped on the forums from our users. Some respond like photoperiods and keep growing normally, others respond negatively by stretching. When they stretch, they can end up easily outgrowing the unit.
As such I would defer to the champions here who have grown Autos such as @Mpower11 @SilverGrobo @Bplatinum9
It’s a great question, but let’s see what the pros are doing! I know @Aang has done Autos previously and has had success as well.
