The Mega Crop Thread

[AdaminCO]

You are assuming Mega Crop weighs the same as sugar by volume, which it does not. Does a quarter teaspoon of lead weigh the same as a quarter teaspoon of talcum powder? No, they have different densities. Same applies to Mega Crop. Myself, I find 1/8 tsp is close to a gram. Others say there are 6g per tsp. You really need to weigh your own samples, with your own spoon, on your own scale. Either way, I'm pretty certain using 4g per tsp as a conversion factor will lead to overfeeding by 50-100%.

Understood. Common sense should give you a feel for the difference in weight and you can adjust accordingly.

On that point though, how do you decipher the weight difference per surface area when dealing with those big ass pellets vs the sandy grain like material.

I see it as splitting hairs. You can’t be perfect. Each plant requires a different amount of said nutrient regardless. The true way to measure is to know/watch your plants... adjust accordingly.

I think the difference between the weight of a grain of sugar vs the weight of grain of whatever is in the mix is negligible, but the conversation I offered is better than holding a paper clip in one hand and trying to mimic the weight in the other.

Say I need 10g to mix in 5 gallons. Conversion says 2.38 tsp to 10g.
Any logical person would know that MC is heavier than sugar, so I would adjust accordingly and probably feed 2tsp, not 2.5.

its wise to switch 3 weeks in flower

It's no problem switching to MC at any time. If you want to use up the old stuff that's fine!

I don't understand these ballpark estimates. A scale is $11.00 and won't leave you wondering if MC is 25% heavier than sugar or 35%. It takes 20 seconds to get the right weight; not that much slower than getting it into a teaspoon. And faster if you need more than a teaspoon.

If switch should I do a flush first follow by a feed right after or no flush just feed MC

These pictures are from a a white widow and an alaskan purple. Both are 30 days in veg Anthony were last fed with 4ml gal of MC, pro tekt, and calimagic.
I'm using ff happy frog soil
Kind k3 xl600 lite
18/6 lite on/off
Temp lite on 78-82
Temp lite off 70-72
RH lite on 35-45
RH lite off 25-30

What's up with these leaves. Here are the pictures. This is a comparison grow as I have three of each kind. All from seeds. Comparing MC against AN beginner schedule and AN intermediate schedule. Only seeing this on the two MC plants.

The damn little balls in Mc pack some weight, I try to pick some out and replace with powder.

 

[Zooie]

I crushed mine in a food processor, works great....no more little balls.....lol....

 

[BooMtoLate]

Lol that works, I'll have to bring out the big guns. It's Hammer Time.

 

[Zooie]

My fingers and hammers don't get along well, like so many other tools. I will stick to my kitchen appliances, of which I am familiar with...….lol

The kitchen is a dangerous place full of weapons, sharp knives, dull knives, frying pans , and rolling pins galore! Why oh why do we have the cast iron frying pan? Light weight aluminum is so much easier on the noggin!

Nothing like a steak in cast iron.

Lol, those weapons are sometimes needed for other uses not intended for...make a wrong move and out comes the rolling pin....with attitude...and the look in the eye to go with it...

at first glance it looks like mag def, feeding too light, and the pots look too small.

I will up the MC to 5gm a gal on next feeding. They are in 1 gallon cloth bags. I'll check the roots when I get home today.

Hey all! Happy friday!

Im currently using green planet 3 part for my 2 autos and about to run out of Massive, npk is 1-2-3, this is the most used secondary nute from feed schedule at 5ml/litre. Wondering if any product would be comparable in the GLN line that could be used instead, and also to be used with MC
Im going to run MC so dont want to load up on Massive again as this will be my last grow with green planet.

Pics have info on this product

recommend doing a run on MC alone. MC pretty much requires learning the nute before experimenting.

way too many growers are caught up in a 3 bottles good, ten bottles better mentality. it takes some time to realize you've been had for years. especially since most nute lines make it impossible to get decent results, as they developed the line with selling the extra junk as a necessity.

if you insist on using pk boosters etc, then make use of the elemental calculator, so you remain in balance. or risk blowing things up in a spectacular manner. make sure you also have a read through @farside05 's and @Emilya 's journals, as they both have successfully explored pushing the envelope with MC and other additives.

Hey all, new member. Happy to have places like this to obtain information, and help where I can. Switched to Mega a few days ago after a water change on day 11 of flower. Started running the Heisenberg tea before flower in my rdwc system. Only on my 4th run indoors, have only ever run flora nova bloom.... for all stages (germination/seedling/veg and flower). It’s been my experience that when my PH starts to drop that my plants are drinking more water then Nutes. Causing a build up of nutrients, hence the PH drop. Also noticing that when using the tea they’re not using as many nutrients. (All this based on my limited experience lol) Been reading this thread and seeing a lot of people running 5-6g. Currently I’m sitting at 520 ppm and staying steady, but my PH is dropping. I’ve learned to expect some PH swing after a water change. Curious if anyone else is running bennies and encountering the same thing? Before the bennies in Veg I was running at 540 ppm no problem. First week of flower (and tea) Ph was unstable, dropping until I hit 480 (500 scale) I’m wanting to get my PPM higher but am worried I’ll have the same PH battle for the next week. Thoughts?

MC does not act the same as other nutes. it is important to learn to feed by read not ppm. no one really feeds by ppm in MC, they just track it.

start with recommended dosage, then adjust from there according to how the plants react and look.

ph in hydro with MC is still a thing, and i recommend it, but many ignore it altogether. MC is generally available to the plant across a much greater range of ph than other nute lines. ph is for the nutes, not the plant, many growers do not understand this.

Hi there!

I've only been growing hydro for a few months ( rdwc ), so take what I say with a grain of salt.. But I do run bennies w/ MC like yourself. And I'm running at 6g/gal along with CalMag and ProSI ( 1ml/gal ). This puts my tds around ~900ppm.

Whenever I experience rapid ph drops I look at my roots. In my case, rapid ph drops usually indicate some sort of pathogen activity ( root rot or brown algae growth in my case ). I've been fighting this since day 1, and have used H. Tea like yourself, but I recently switched to Z7 and Hydroguard ( thanks @West Hippie ). This may not be the case with you though.

Edit - I mention this because you noted that you're using Heisenberg tea. People don't normally use the tea unless they've been slimed at some point. Like me.

 

[MrsJack420]

Getting right with Jesus!



(that was for you, @MrsJack420 )








That's been my impression as well. Not that there is anything wrong with that, mind you.







Make/recharge your coco with 1g/gal, properly ph'd. Start feeding immediately.

The following basics assume healthy plants:

- Day 1: 1g/gal

- Day 6: 2g/gal

- Day 12: 3g/gal

- Day 18: 4g/gal

- Day 24: 5g/gal

- Day 30+: 6g/gal



The above presumes healthy growth. That doesn't mean skyrocketing size, but healthy a plant. Some grow faster than others, and mediums can contribute to the speed of growth as well.

Read the leaves. If the plants ask for more, give it to them. If you start to burn the tips, back off by 1/2g/gal for one watering cycle. (For coco, or other frequent feeds, give it a couple days at the 1/2g less mark.)

This is a general, basic start. There are options (like if using RO, you may want a little calmag) to this, but you really don't need them for most cases.

That's always been my code lol especially back in the day seems appropriate anyways

@bluter nailed it.

For a 30-day old plant, you're not feeding her enough. She should have already been at the 6g/gal mark. By the combination of what you're using, I see you are using the @farside05 schedule. Are you using it correctly? It's all a 11 ratio mix based on the amount of MC you feed. Whatever number of g/gal of MC, then use the same ml/gal each of calmag and protekt.

Mix in the protekt first, then add the calmag, and then add MC. Note: the silica supplement will try to push your pH up a good bit. While you shouldn't have to adjust it for soil/promix, it may be a good idea to spot check it and see if it's really high. If it is really high (like mid to upper 8's or more) then you may consider (but don't have to) bringing it down just a bit into the upper 7's. You don't have to, but it can help the soil buffer it easier.


Next the pots are too small, and you may be over-watering a tick. Get them potted up into at least 7gal, if not 10gal.

Why oh why do we have the cast iron frying pan?

First and foremost???



Chicken.

(Then pork chops.)

at first glance it looks like mag def, feeding too light, and the pots look too small.

Bingo!

ph in hydro with MC is still a thing, and i recommend it, but many ignore it altogether. MC is generally available to the plant across a much greater range of ph than other nute lines. ph is for the nutes, not the plant, many growers do not understand this.

GLN recommends a pH of 5.5-6.5 for hydro applications. No way should that be ignored with any hydro application. Protekt or soil? Sure.

Z7 and Hydroguard

For the win!

Money well spent on these.
