Questions with MegaCrop

Project Ponics said:

Couple quick questions. Would like to know the answers for both growing in coco and soil as I am growing two of the same strain autos, one in coco in 2gal pot and the other in happy frog soil in 3gal pot.

1. What should I target my pH levels at?

Soil I’ve always just got it inbetween 6.2-6.4 and that seems to be going good. But how about coco? I know they say between 5.5-6.5 but I was told to always pH at 6.5. For both soil and coco? Is there a “sweet spot”? I notice when I pH at let’s say 6.2 when feeding in coco, when I pH the waste it’s around 5.5-5.8? But the ppm is correct as it should be when I check it. Is that normal for it to drop a couple digits after running through the medium? I don’t even check the waste from my soil plants of course, unless I find a problem or reason to check the pH.

2. What should my feed schedule be, or recommended?

Soil I usually always do feed, feed, water.

But switching to MC I was told to feed every watering? So I have not gave either plant a plain pH watering since the first feeding, up until two days ago they got their first plain watering. I have been giving both plants full nutrients every watering which has been every two days, they seem to drink up fast! Yes, I’ve even been feeding the coco plant the same way/time as the soil. Not the right way to feed when growing in coco I just figured out lol. But hey, both plants looks amazing so it worked out.

3. I was told to feed the coco plant 2-3 times a day? 2 cups/16oz of nutrient water. Is that how plants In coco are suppose to be fed I’m guessing?


Even though I may have been feeding the plant growing coco wrong, she turned out just fine!

Picture of both plants.
Left - Coco 2gal pot
Right - Happy frog soil 3gal pot

***Both plants are 32-34” tall and have been growing under a single 300w (136w pull) viparspectra led***
Pretty impressive veg growth/flower stretch on both of these girls for being under a single cheap 136w blurple and using nothing but MC. They are both about 3 weeks into flower, going under a 300w strip led this week!

You have done a great job,this is clear by how your plants are looking in the images presented.I primarily use coco (a 50/50 mix with perlite), the PH of the water I tend to go with is 5.8-6.2 .My feeding schedule tends to be once every day to 2 days, but I generally stick to a lighter feeding (water soluble nutrients) and water from indicators such as the dryness of the coco (measure with my thumb to see it if the top inch is still damp).I don't use a very structured schedule, focusing on flexibility that caters to the individual plants needs in the grow.However with my EC I generally keep it at 1.3 through the vegetative phase and when (before switch I flush) I switch to flower the first week I raise the EC to 1.4-1.5 then continue every week to raise it by 0.2 EC till week 6 where I start the flush, then proceed to harvest later on when the trichomes are milky.

Hope this helps and Happy growing.

For soil I never ph my feed it’s pointless if it’s good soil. For coco and any hydro I keep it at 6.2 and let it drift. With mega crop I’ve never had to feed over 800 ppm the entire grow and slowly taper off towards the end of flower to about 200ppm until the chop.
