hey hempsters

calling mega crop users.. simple questions..

are you following the mc nute schedule ?
or are you dialing it back to a lower ppm ?

is anyone using the bud explosion ?
and are you just adding it on top ?

tossing some plants into flower and changing the nutes to mc today.
any replies appreciated.

I use megacrop and suggest that you use there recommended dose, 1 gram per 1Gal of water. I also added 1tsp per cal of calmag and just increased the doses when I saw nutrient deficiencies.

Of course on seedlings use 1/4tsp per gal.

I just looked at the Mega Crop recommended feeding chart. They recommend 2 grams/gallon for seedlings and increases from there.

I do have to add that where I said I used 6.5 grams / gallon of the MC I that was for plants well into flowering. Weeks 3 till...…..

Meh. Ive always used 1g and went up as necessary. But dont read my thread. I purposely used wayyy too much per gallon and it eventually caught up lol

You can always add more later. But ya cant take it back out really if needed.
 
I’ve had my experiences pushing plants with too many nutrients, and it always ends up with the plant in some kind of deficiency because of too much of something else.
For me now, it’s easier to go with a lower dose, and address any lower leaf fade with a slight increase.

Cannabis has almost always performed better at half the manufacturer’s recommended nutrient doses.

The only exception I saw to this rule was using RX Green, and when I return to growing that’ll be my choice. Those plants performed beautifully with a full dose and just as well on a half dose. But the impressive part for me was that at full dose they were still vigorous, healthy, bountiful plants.
 
got the plants moved last night and mixed up a test batch of the mc.

checked the online feed calculator and went essentially with that. hit my target ppm at roughly 8 grams mc to 6 L water. wound up at 840 ppm, i target between 800 - 900 for the stage my plants are at on the old AN nutes, will have to see if they are ok with the ppm level on the new suff.

did not add any cal-mag yet. got the 9-6-17 formula, and have been fishing for info on if it is the new or old formula. i might have to drop a 1/4 to 1/2 gram of the nutes and add 2 - 3 ml of cal-mag to compensate. want to see if they do ok without for the time being.

pics soon.
 
Those little "dollar store" plastic trash cans that were discussed a while back, that are available in black and white versions, and that appear to be advertised as 7-quart capacity but have "5.5 liter / 5.8 quart" (if I remember correctly) on the outside bottom...

I'm not where they're at, lol, but if I decide to wait until I am and measure them, I'll probably forget my question until I decide to "drill and fill." I just did a web search and - if I found the correct advertisement - the advertised dimensions are:
L: 9", W: 6.875", H: 10.5"

I'll be using perlite, and probably only that (my vermiculite spent years in an oft-flooded and likely moldy basement :rolleyes: , so I'm wary of using it) for the medium. Temperatures shouldn't be extremely high (although they might be in the 90s initially) because we get Winter here and I always have trouble trying to heat the house to "long-sleeve shirt and sweater" conditions.

How high up should I drill the hole?

Thanks in advance.

I tend to agree, as a generalization. But it varies depending on factors such as strain choice, size of plant/container, amount of light-energy the plant is receiving per day, temperature, CO₂ level, how much O₂ the root system has access to, et cetera.
 
This may have already been mentioned. If so... apologies. I got way behind with the thread and am playing catch up

Has anyone seem to find if vermiculite blocks the uptake of nutes when mixed at 50/50 with perlite??

Consider: Plants that have a high degree of oxygen available at the root zone are more efficient feeders. Therefore, plants that have less oxygen available - or that have difficulty accessing it - will be less efficient. The more vermiculite in the mix, the more water it holds - until there's so much that the plant's root some becomes waterlogged. That's bad in a soil grow, but don't really exist as an issue in a DWC hydroponic grow because that water (nutrient solution) is constantly being actively aerated. That isn't happening in a passive hydroponic grow. And that means it's possible to have waterlogged roots in a hempy. Now there are degrees (so to speak), and the other end of the scale is "dry / no moisture at the root zone," lol.

Er... Rambling. I'm thinking that more than 10% to 15% vermiculite and the amount of O₂ available to the roots starts to decrease.

IDK.
 
How high up should I drill the hole?

generally anywhere from 2" - 2 1/2".
mine are at 2 1/4".

i don't use any vermiculite in mine any more. the vermiculite was holding the moisture and drowning my plants. my hempys improved the moment i deleted it.
 
If the plants grow beautifully in pure perlite why mess with it adding other things?
 
If I remember correctly, I think the “original” hempy called for a 3/8” hole to be 2” above the bottom. I have been using a 1/2” hole about 2” above the bottom.

The reservoir is there to provide some buffer between waterings, so that one doesn’t have to water every day.

But I believe an excessively deep reservoir is counter-productive. The hempy grow really benefits from the increased oxygen provided by frequent watering, and if the plant isn’t drinking it all up in a couple of days, the reservoir can start getting funky without active aeration. So, if I am around, I fertigate younger plants frequently, with a lower concentration of nutrient solution.
 
I know I'm not normal so if you're interested in trying your hand growing in perlite/hempy DO NOT do what I do as I am pretty sure I'm the only one who does it like I do.

I too put my hole 2" to 2.5" up from the bottom. The hole is 3/8" to 1/2" in size. I thoroughly, and I mean thoroughly wash all the dust off my perlite. I prefer the medium size perlite. Skipping forward to when the roots have reached the reservoir..………. My daily routine is to remove the piece of duct tape covering the hole. I pick up the pot and pour out as much as I can from the reservoir without pouring out the perlite on top of the pot. Then I set the pot down and pour/fill the reservoir pouring from all areas of the top to effectively soak all of the perlite on the way to the reservoir. I let the liquid overflow the hole and when it's about stopped coming out I tip the pot back to stop the flow, dry around the hole, and put on a small piece of duct tape to cover the hole.

Now, I have never grown anything other then Dark Devil autos (5 of them) in hempy and one @SeedsMan Blueberry plant. But they all flourished and grew beautifully. The autos at about 50% nutrient strength. The Blueberry closer to 75% nutrient strength. Once a week I would add 450ml of H2O2 to my feeding mix as a treat for the plants.
 
i drill a 1/4 " inch hole 2 1/4" from the bottom. i have plugs i use when i feed/water. i plug the bucket, feed/water, then let stand for a few minutes before removing the plug to drain.

to flush i use h202 at 1ml/L ro, plug the hole, fill to top of the bucket, and let stand 20 min, then let drain. none of this fill to 3 times capacity stuff. clears stuff out first time every time. plants will need feeding 12-24 hrs after.
 
I am unable to fill to top of bucket as my perlite floats.

i usually get root structure holding it all. i leave the perlite an inch or two from the top and let it float up to the brim.
 
interesting discussion about hole height. i am dealing with so many hempy issues right now,, mostly ph,, but i recently raised the height of the holes in my pots from 2 3/8 to near 2 3/4 ", so i am wondering if this might be adding to my issues,,

two inch high holes would indeed require watering every two days,, which i was hoping to avoid

lots to ponder,, thanks, and cheers
