I'm back to vert... But with a few questions/problems!

I have a 5x5 grow tent and I noticed I have to run my plants in a vertical grow style. In my 4x8 grow tent the temps hit 90 degrees Fahrenheit using an air cooled hood. I'm sure a vertical grow style will run cooler due to the improved ventilation aka no hood. Are 2 600w bare bulbs cooler than a 1000w bare bulb? Just trying to learn from others. Also when is it pointless to add more light during flower. This summer heat is no fun. My plants are about 20"tall in 10 gallon fabric pots. Growing no-till style.

If you have a switchable thousand watt magnetic ballast, try the Philips 860W CDM bulb. Vertical only but they run pretty cool. Open fixture rated so it can run bare.

I've been running them for quite awhile now and I'm pretty thrilled with the results. You'll want to run your nutrient strength a little higher with them vs HPS.

I was able to get the temperature problem fixed. Here are the plants set up.

i found a 20" box fan works better than 10 or 12" vornado style fans. it makes a much wider column of air that hit's the girls with plenty of cool air that gets their leaves moving before lifting heat from the bulb.

They do a great job, don't they? I run mine on low, even.

only reason to turn them up is to counter excessive humidity to prevent pm. otherwise it's a waste of electricity and it can be to much of a good thing. you want the leaves to be moving in a firm breeze, not flapping like their in a wind storm.

How big you want them to get? Tall plants in vert will want more light.

drekoushranada · Aug 30, 2015

I agree. I would do a bigger fan but I just figured would use what I have. The room is doing really well though.

They are about 5-6 feet tall depending on the pot. The skywalker Kush is the tallest.

Then you're going to want at least 1500W, preferably over 2 kW if you can get it in there.

I would but I can't get that in a 5x5 tent without problems.

Okay, so your issue is going to have more to do with light distribution and intensity. If you run two x 600W HPS that would do you really well. Thouies are marginal and a DE would fry your shit- if you could get it vertical in the first place.

You could have a second HPS thouie up high, you'd just want to remove the top of the tent, or the equivalent to get enough ventilation.

I've run as many as three 860W CDM lamps in a vertical stack. Worked bitchin' too- but it's a lot of watts both to run and keep cool.

i train each girl in flower in a rear scrog made from a section of wire fence held with bamboo sticks.

I actually use to do the same. But only when I had an open grow area. It can be done in a tent but I just wanted to see how these strains responded to being left alone. This is my first run with all but one of them.

drekoushranada · Aug 31, 2015

Here is an update of the flower room. They are 28 days from 12/12 and grown from seeds. In case some of you all are not familiar with my style of grow it is no till and this is what you will see once you pull back my hay mulch. :bigjoint:

pilsung · Sep 1, 2015

nice. eventually i'll be doing no till but i'm not sure if i want to do several 30+ gallon bags or if i want to build a box big enough to hold around 200 gallons of soil.
the simplicity of tending to no till is especially attractive to me because i doubt i'll ever stop making grower is a stoner errors and no till would help minimize them.
but for now i'm liking how the 3 gallon cloth bags fit into a 5 gallon bucket with 6 - 8 inches of stone and perlite at the bottom. leaves enough around bag to air prune roots and i run an air stone under the rocks to give oxygen to the roots that grow through the bags bottom.

Hmm. That sounds pretty cool. You have any pictures of the set up and roots?

pilsung · Sep 1, 2015

the second pic in post #14 shows how nicely the 3 gallon bag fits in a bucket. sorry i haven't taken any shots of the roots.
the first couple runs i used these smaller buckets i got at a dollar store.

i found that when girls get mid way into flower they need a bigger reservoir than these so i've switched to the 5 gallons.

it gives me a lot of flexibility.

drekoushranada · Sep 2, 2015

I might give this grow style a try.
