Week 8

Just started flushing with clean H2O

Some of the colas are looking kinda crispy... contemplating them now and the rest at the end of the week... I don't think I can push 2 weeks of flush this time.

That leaf a while back - looked like potentially spider mite damage - be sure to next time check for bugs as well as nutrients.

I think your PPMS could of been higher.

The high heat from the HPS is good - just like the radiant sun.

You need a stronger fan for the cool tube - using a Hydrofarm 400cfm 6" fan for 90$ you'll cool that bad boy with zero worries plus it'll increase your exhaust cfms which passively increases your intake so you will constantly have fresh air and cooler air. If you have a carbon Filter

Are you making the A/C cool the room with the tent or just the tent? Exhausting the heat out of hte whole room will make a MASSIVE difference.

I say run the light at 100% and just lower the plants or raise the light.

Ganja grows in Afghan... its fukcing HAWT AND DRY and we always treat it like its a bromeliad growing in some tropical jungle.

Its a weed - tough plant :good:

Now regarding your grassy smelling weed. Be there.

Dry it longer. Next time you harvest take off everything with NO FROST.

Leave the rest on and dry em in a cool high air flow "dark" if you can place. Give them 5 days if its hot n dry say 80F and 40% RH.

Give em 7 days it ifs 75F 50%RH and 10 days if its 70F 50%+ RH.

You can tell by the stems - the big stems wont' bend - they will snap - dry.

That point you take out ur non stick parchment paper - put the dry buds on there and do what I call the "double standard" trim. Basically take all those frosty leaves off you might have taken before and stash them for some concentrates - butter - w/e you want... tea.

Now you have ready to smoke buds :D They should smell strong too and the cure is only going to make them better.

Your root picture btw :respect:

You doing a fine job brother - nice grow - its fun!

Hey there!

Could have been spider mites, but the rest of the grow was unaffected. There has been no huge outbreak. I've had those bastards before.

Currently, I can't exhaust heat outside. It's just not an option. Also, I can't lower the plants, nor raise the light. This is almost a micro grow... and 100% power would cook these ladies. It's already upwards of 90f in there.

I think the PPMs could be higher, but I've read that under-feeding was better than over-feeding. Also, when the small res. evaporates, the PPMs raise due to concentration. So, at first the PPMs may be low, but after two days, and 2-3 gallons of water evaporating, the nutes are more concentrated.

Thanks for the curing tips!

Woot! Looks like my storage just kicked over.

The 600w HPS Cooltube is ready to be kicked on - just waiting until the end of the month so they are a bit chunkier

They have been pretty hearty so far, but there are signs of problems. Cal/Mag deficiency and PH fluxuations? I'm not sure. They are a bit too yellow at the tops I believe...

Also - what causes purple stems? Genetics? Nutrient issues? Temperatures? In a previous grow, one plant had this quality... guessing it was genetics then. My last grow, with these same genetics, there were no purple stems. The mothers started turning funky colors... nutrient buildup? rootboundness? temps? ph? I don't know, but I'm not stressing too much. It would be nice to feel I really understood hydroponics though! haha

Edit: After a bit of reading I found that a lack of nitrogen can cause stems to turn purple. Am I going too easy on the nutrients or was the out of balance PH causing nutrient lock-out? whoa, I might be starting to understand this!

This is my second hydro gro, so if you have suggestions or tips, let me know! Thanks for watching! Keep it green

I bet that is from mixing up your nutes to fast and getting lockout. if you don't stir up your A enough and don't wait 10 minutes or so before adding the B, the calcium will lock out of your rez. When I use general hydroponics that happens to me.

Also, purpling of the stems and black/dkpurple spots are a phosphorus deficiency. you could try adding more P. could also be a mixing issue as well.

I started with GH and switched to advanced nutrients and then to botanicare pure blend pro which is one bottle; not two :biggrin:

a handy tutorial to understand how your ph works that I found very useful when understanding ph fluctuations is the ph manifesto which you can find using google.

I have read some debate also with h2o2 and if it really oxygenates because of a chemical process making the extra oxygen not available. I use Dutchmasters Zone which is stronger and provides copper as well.

in conclusion...

in conclusion...

I thought i'd wrap up this thread...

The chop was easy...

...and the roots were a healthy network!

a nette pot, an unused site, was totally overgrown as if it were growing a plant

no muss, no fuss

This system has so little waste, so little stuff to deal with... i must say... this round of growing was not very labor intensive...

picture.php


and to clean up, you just roll it up... something we are all familiar with...

picture.php


and quite the bit of flowers were produced

picture.php


about 10 oz in all!

picture.php


the high is racy... very clean and uppy. the strain came from a bagseed that wasnt super dense. the seeds produced a plants - one more sativa looking and one that was more indica looking... and this is that one that is more indica looking, but by saying that i mean that the bud structure is more compacted and less airy. the high isnt an indica high

this strian is gone, but some more are in the works in Round III...

thanks for checking out the thread!

cool grow :) tho i bet if you had filled up with the leca rock to the same height as the netpot's i bet you would have up'ed your yield atleast 30% look's like that root zone could have used some air try and throw some leca rocks in the before you start veg's next time man

keep it up :)

Thanks for the advice! On the last grow, I did exactly what you suggested and at the end I was left with a TON of clay pellets to sanitize. I wanted to try this method of just letting the pots sit on the bottom of the tray with no sea of pellets to reduce the amount of labor, and the time, in between grow cycles.

The tray would flood for 15 minutes a few times during the 12 hours of light and that's about it! I thought it would be too long, but there were no significant issues from what I saw.
