The Official Hempy Bucket Thread

Thanks for the advice guys, I'll try to pay less attention to it. I already have some 10 gallon containers sitting out.

How long can water sit before losing oxygen at a obvious level?

 

[RetroGrow]

Water is H2O. Two atoms hydrogen, one atom of oxygen. It will not lose oxygen unless boiled, or unless there are organisms in the water consuming oxygen. You can increase the oxygen levels by bubbling, like done in aquariums.

I have always wondered if that was ok , to let my gallon jug sit for a day or two before total use. The oxygen level in the jug should stay where it is at?, unless organisms consume it. Thanks

 

[RetroGrow]

Yes. Water is H2O. It doesn't go "bad". Only boiling or algae/other organisms will consume oxygen.

Speaking of algae.. I've got some serious green in my waste tray.

Would it be correct to assume that algae is in part causing my rapid ph swing?

Hasn't happened to me before. New light setup on this grow. 600w 6000k metal halide dimmed to 400w for veg. Height is about 18" above the plants and containers (cooled of course). For prior grows I used a massive CFL which generated much less heat and light.

I do see some green colored perlite on the very tops of my containers. Digging down a bit - still white. So, hopefully it hasn't reached the insides of my hempys.

Here are the ladies -

Dinafem Critical Jack. 46 days from germination. Guess which one popped first

Edit:

There is another (oh shit!) tray below the tray you see in the pic - no algae in the pic. Tray in the pic is there on top of a stool to raise everything up while they are small. My reflector exhaust duct is vertically challenged.

Oh - Temp on thermometer isn't correct. It was hanging above the reflector a min before the pic with the outside probe at canopy.

Is the green coming from your buckets, or is it just growing in the waste tray?

If it's the latter, it's not affecting the ph in the buckets, and can be solved by cleaning up the waste water after watering.

If you have even a little water in the trays, under the lights 12-18 hours a day, algae will come. It's not good, but it's not that big a deal imho.
good luck

 

[seeingthings]

I don't think it's coming from within the buckets. I do leave a bit of runoff to bump up humidity. Most of it is sucked out every time I water.

I haven't changed anything in terms of leaving some runoff etc. Just the light source. Never saw the algae before so, had me thinking.

I've run this strain. Highest yielding strain I've ever seen, however, yours are not nearly as big as mine were at that stage. I was in coco though. It looks like you are in straight perlite? I used Maxibloom, with Canna Boost (triacontanol) which is a growth hormone. You can get straight triacontanol from MBFerts.com. It makes plants much bigger, and is cheap from MBFerts. Use it every day throughout grow, veg & flower. Other than size, they look O.K. Mine in coco Hempys with a two month veg were huge, and each one yielded minimum of 8 zips. If you water/feed to runoff EVERY day, they will get big fast, as the fresh rez brings fresh oxygen to the plants. Start watering/feeding more frequently, at least once a day, and they will explode. Yours are lagging a bit. NOT a criticism, just my advice. The more often you replace the rez, the more oxygen, and the bigger they get. It's a small rez, and the plants use that oxygen fast. Not just about the nutes.

That's great news! I did quite a bit of research on yield before pulling the trigger on these beans.

I did just recently top them, the back right plant has been the fastest growing of them all. The others popped later but are still moving along.

Oh- the 46 days from germination. Thats when I first saw the taproot emerge. They started off really slow. Winter ambient temps in the house this time of year are really low, in the mid 60's with 20-30& RH. I had a heat mat but it shuts off automatically every few hours.

Hopefully they get bigger soon?

Any advice on their preferences in environment & nute levels?

Yes- 100% perlite. I'm all over the triacontanol. Funny thing, I purchased my solis-tek ballst, bulbs and ordered a reflector yesterday from MBFerts. Their prices are fantastic! Only thing that turns me off about the triacontanol is prepping it. I did some research and it looks like a pain in the ass. Easier than I think?

O.K. So you topped them. This strain likes to grow very tall, so topping could explain their short stature. If you don't have high ceilings, topping can help keep them from going into the ceiling lights, if you are not using vertical lighting. I did them with vertical, so they got really tall, and stacked bulbs made fat buds all the way from top to bottom.

Man.. this tent is 7ft tall too. Oh well - I topped too much on my last grow. Barney's farm laughing buddha and sweet tooth. So many branches.. Holy shit..

Hopefully all is not f'd.

I looked into mixing the tria. Not as hard as I thought last night haha.

 

[RetroGrow]

It's O.K to top them if you don't have high ceilings. I had 10 foot ceilings, so let them rip. They'll be O.K., but are Sativa dominant (Jack Herer) and like to grow tall. Outdoors, they get really big.

can someone tell me if i can hempy with perlite mixed with sphagnum peat moss? kinda need to know ASAP. please and thanks family

 

[hush]

I've never tried it, but I would be concerned about pH problems. Peat decomposes fairly quickly, and it acidifies as it decomposes. To be honest, if you have access to perlite, but not vermiculite, I think you'd be better off using straight perlite instead of trying to substitute peat for vermiculite.

Are you asking because you don't have access to vermiculite? Or because you have a surplus of peat you need to use up?

 

[glockdoc]

hey thanks for speedy response, i had thought pmoss could substitute for vermiculite, guess i was wrong..i bought it with the intention of layering the top 2 inches of a perlite based hempy so the seedlings would have plenty of water to survive (without my paranoia) until roots hit the res. was thinking i could get away with top feeding every 2-3 days with the p moss but if need be ill pick up some vermiculite.. i do have hydroton sitting around as well!

food for thought thou my tap water is very very hard, ph of about 8-9+...would that buffer out the peats acidity?!?

 

[hush]

I really don't think that hardwater will help out in that way, but i don't know for sure. All I can say is tread softly. I actually think you would be better off using straight perlite than experimenting with peat. But that's just a hunch.

 

[glockdoc]

im just going to be a sheep and follow suit by grabbing some vermiculite. your insight was enough to convince me to do so. that said, could i leave like a 1 inch layer of vermiculite when i insert the seedling ( seed with taproot out and seeds started in plugs) to prolong the hand waterings?

 

[glockdoc]

done plenty of soil grows this will be my 1st shot at hempy and dwc and i wanna try a small hydro bed for a couple of small plants. got anymore insight for me?!?!

 

[glockdoc]

btw 400 in a 2x2 is nice aint it! heavy feeds, more airflow, great yields! i do got u beat by 6 watts im in a 1.5x2.5 106w/sqft
