World Of Hempy

Question to the general Hempy community: Since neither perlite nor vermiculite have any nutritional value, how soon do you start feeding nutrients to the young plant? Also, how often do you feel the need to flush this rocky medium?

I transplanted 2 clones into Hempy Solo cups yesterday, and will start a light feeding today, and ramp it up as their roots start to hit the res. I have two weeks to go on my 3 gallon run, and have only flushed them once, and that was really JUST CAUSE I thought it might be a good idea, not because there was a problem or anything.

Here's my hempy girls just under 3 weeks. I am mainlining for four nodes. All the plants have been topped once and some of them just got topped for the second and last time. Pics 2,3,4 are of the same plant and 5,6,7 are of another plant before and after the second topping. With the second topping came the removal of the first node shoots and leaf and removal of the second node sheets (I left the leaf). What do you guys think?

Looks really good georgy. The 1st plants lower leafs look a little too limeish in color to me, looks like it could use a little "N". I'm really interested in the main line concept also. But I have to get my grow squared away, I want to grow out some of the new crosses I made to see what I ended up with and don't want to take that much veg time to ML.

Are you going to tie down the 4 arms to spread them out a little or just let the 4 tops run up the middle?

Here's a quick update on my outdoors bucket. The Maui-Wowie ex-mom is now on day 25 of showing flower, so in 12/12 days I'd say around 42 of 55 for this strain normally. I'm guessing it will take another 3wks. So unless we get some freakish weather I should finish prior to frost. She is really starting to pack on the buds and starting to frost up a bit.



I'll get some Bondage shots of the indoor grow after the lights come on tonight.

Thanks man yeah the yellowing of the leaves has gotten worse on a few of the plants very quickly in the last two days. I have fed the plants with 1/4 strength foliage pro (9-3-6) plus pro-teKt twice but gave them straight water last feed when I had noticed some minor burning and leaf curling on some plants. My temps sometimes get as high as 93* so it makes it hard to diagnose problems as nutrient or heat related for me. Two plants of the same strain have been fading from the bottom leaves to the top, from the center of the leaf to the edges. Brown little circles are spotting the affected leaves. It has gotten significantly worse on one plant over the course of 2 days. I will be feeding tonight would you suggest I use foliage pro (9-3-6) or grow (7-9-5).

As for the bondage I tied down the 2 shoots that came off of the first topping after I did the second topping. If you go to the main lining thread I am doing exactly what nugs does in the 6 pictures in one of the first post that shows the plant from the first topping to the recovery of the second topping and tie down. When the four shoots have turned to face the light and have a couple of sets of leaves on them I will switch to 12/12. I don't want the shoots to spread out that much so I can keep the plants close together.

Here's a picture of the most problematic plant. Is this a specific deficiency or is it burn or is it from the high temps? I posted it in the plant problems section and no one ever came by to help me out. This is fruity mids #2 and fruity mids #3 is looking like this one did a day and a half ago.

hmm that prolly happened cause the algae from the perlite is creeping up the leaf or it just is letting it die off. I'd just cut off the bad growth, your other growth looks nice and healthy dont worry!

Thank you man I hadn't even considered the algae. Will this continue to creep up the plant?

@ georgyboy, To me it looks like a ph problem is leading to a lockout of some sort. I'm sure your ph'ing but I have to ask.
As far as which food I'd go for the one that has a full line of micro nutes (cal, zinc, boron, copper, iron, mag, cl,,,,,) My 2nd guess would be a micro due to the rusting of the veins, which isn't normal for the big 3 nute deficiencies.

update!

My water is always 5.8 when I add it to the containers but I checked run off ph last week and it was high at 6.4. I have just stayed on the 5.8 hoping things will balance themselves out. Should I water with a lower ph?

georgy boy your plants are fine, sometimes the bottoms will fall off thats okay it just knows that those leaves sucked and it only likes its fresh growth. do it a favor and cut off those bottom leafs

does this mean your hempy buckets are getting to 93? do whatever you can to lower your heat, like shutting off your veg room for 1-6 hours a day, possibly during your peak heat hours. Its okay to have heat stress on the plant but if the heat is getting your roots hot that is bad

Georgy Boy,, Those plants are too small/young to be dropping lower leaves like that. Make sure you are giving them a Balanced Feed, and Get some CalMag into their diet ASAP..

georgy - Your ph is fine. 5.8 drifting up to 6.4 is in the good range. 93 degrees is too high if you can get 10 out of that, I think most everything else will be controllable. What's your lighting and vent situation?
And as rusty said feed them. I looked up Dyna-gro and the foliage pro (9-3-6) you have would be perfect. One thing to mention about feeding in hi temps. I've found that the plant will need more food when the temps are up. I don't know if its the pant is using more or if the nutes just don't have the same punch in hi temps. I use Osmocote which is controled release fert, so I put in a full grow's worth of food in the bucket at the start, and I've noticed that if I'm dealing with 90 + temps that the food will get used up before I finish. Just can't say if its the plant or nutes.
With all that being said instead of the 1/4 tsp/gal on the feeding chart I would double that with your temps.
The foliage pro has cal & mag in it but I wouldn't hesitate to add an additional 1 to 2 ml/gal of CalMag to the mix.

Love the updates. 1st let me say you are breaking new ground in the hempy concept, with trying to expand the rez. So don't take what I say as too critical, because I want to see if this will work. If you've read the thread you'll know I've broken a lot of hempy rules and have had some good results, I haven't mentioned too many of the failures.

First I have to say what you've built is a lot closer to dwc than hempy.
Next with using the party cups for the full grow (unless I don't know of a step you still have upcoming) you are going to limit the amount of room for root growth. With your set up with a water line above the hempy hole the roots will grow out of the hole into the rez but I don't think enough to make up for the limited space in the cup. A plant can't give more bud than it has roots. This is why the avg 2L hempy is around a 1/2 oz, and you're not going to get 2 oz from a 2L there is not the root space no matter how well you maintain. If you are looking for a quick 1/4oz per then you're on the right track.
Your idea of pushing air back up through the cup is new also, a hempy is based on O2 being drawn in from the top, & I don't think you can seal the tub well enough to make it happen, but please prove me wrong.
Last as I look at your photos they look a little water logged to me. So you need to find the sweet spot on the frequency of drying out the root system.

So please don't take me wrong, I want you to succeed, I just see a few shortcomings.

There have been a few times that I reached in the closet and grabbed a container and noticed it to be alarmingly warm. It has not been consistent though, just occasionally some of them feel warm, and I know they shouldn't. It happens more to the ones under the cfls, and when they have a lot of water.

The dyna-gro feeds are all complete feeds and except for their bloom they are all very balanced. I don't have calmag but I do have MagPro which is a mag and sulfur micro feed meant to be used in bloom. I watered last night with the grow (7-9-5) and Pro-teKt to see how they respond. My run off on all the 50/50 plants was 5.8-5.9 and the nutes are solid. The new growth continues to look healthy so I am thinking that whatever was wrong with it has passed and I no longer need to worry. I will still be keeping a close eye on her though.

Hi guys glad to have found this thread. im on my first hempy grow ever. Mainly done nft and dwc in the past. Im loving how easy hempys are...and no worries about pumps. Im on day 31 of 12/12 with 3 bluedream 2 elephant 1 super silver haze crossed with an unknown and one purple sour diesel.

One of my elephants was in sunshine mix when i got it so i just plunked it into a hempy to let the roots grow out of tne smaller pot....it looks the most healthy of them all lol. I left it in a 2 gallon mormal pot and put it right into a 5 gal bucket half full with perlite. Have some massive yellowing on my large BD where the leaves are under the light....the rest is green. Other than that and some slight burn from an sns244 spray they are well.

Under 600 watt hps aircooled and a vertically hung 400 mh btw.

counted 45 buds the size of a golfball on my large BD and guessing she has about 5-6 weeks to go!

Thanks man, I had the temps down to 88 when I was running the lights 18-6 with the lights off period between 10 in the morning and 4 in the afternoon (the hottest part of the day) but I have a new baby sitter that will be coming to my house to watch my child so I had to switch the lights to a 16-8 schedule with lights off from 2:30 P.M. to 10:30 P.M. If I could cool the room the closet is in I would always keep the door closed and this wouldn't be an issue but I have one large ac in the living room and it keeps the grow room at 81. That is the number I really need to get down because my ventilation is overkill. (450cfm in a 65ft^3 closet)

It interesting that you say that about needing to feed more. I have read somewhere that you need to feed lightly during periods of high heat, I can't remember the reason nor the credibility of the source, but I remembered that and have been feeding cautiously as a result. I will up the strength next feed unless the plants tell me not to. I wonder if TMF respond to differently than liquid ferts. Like I told rusty I don't have calmag, and I'm strapped on cash so I won't be getting it. I have the Magpro, would you guys use that or just let it be. I also have superthrive. I have been saving both for flowering. Superthrive starting day 1 12/12 and Magpro starting about two weeks later when the plants start showing pistils.
