What PH are you suppose to use for Hempy Bucket 4 parts perlite to 1 part vermiculite mix in 3 gallon containers?

If you tell me I'll show you what comes of a 100% Sativa in a hempy bucket.

and, does the PH change when switching the lights to 12/12? Vegetative PH and flowering PH? Is this hydroponics?

She says she liked using a PH of 5.9

I read a post by Hempy himself somewhere that said he liked 6.3

I think the range is 5.5-6.4

Please pm me w/journal when you get it up, I'd like to see it. I'm doing a hempy garden myself in the near future. Can't wait!

There's no one pH that you want to maintain in any hydroponic setting for any plant. The nutrients are variably available according to pH. In other words, the pH you need to let your plant eat one kind of food is actually bad for letting it eat another kind.

So you need to make sure the pH varies within a certain range so that the plant can get a balanced diet. This isn't hard to do, since it's usually a whole lot of work to try to keep things at one specific pH in a hydroponic system. The pH will naturally drift slowly up or down depending on how things are going. That's why you'll see most growers referring to starting their pH out low, for example, and letting it drift upward a certain amount before adjusting it back down.

This lets your plants make use of the entire range of good pH and getting a full range of nutrition in the process. In this case you want to keep things on the low end of what's normal for plants because marijuana is an acid-loving plant. As Bill said, you want to go from around 5.6 to 6.4 to allow your plants a full range of nutrient availability. You don't have to try to create this range in your hydroponics every day or anything, the pH should try to drift on you. All you need to do is monitor that drift and when it gets to one end of the range simply adjust the pH up or down to the other end and allow the drift to bring it back.

If that takes a few days, that's fine. Hydroponics is faster than soil, but plants are still patient.

Great info on PH. I have been looking for this. So... I should probably start my ph at about 5.5 for hydro and let it drift no higher than 6.5? Right now I have neutral ph from my home water (ph-7).

Thanks for the clarification knowbuddy.

For visual learners, here is a chart that shows it as well. Some are above 6, others below it, wich is why it's good to let it vary slightly. But obviously on it's own and not too quickly.

thats gud info knowbody

thats where good nutes make a big diff
first u start out at the right ph because their mixed that way
and then they dont drift 2 far 2 fast because their buffered rite

i just use Advanced Nutrients cause of that
best quality i found
