Yeah Berkelely is hard to come across, It used to be all I bought for a while, it was made by a bunch of kids at Berkeley and is a real upty type of weed, good for smoking before work because of the not super high THC content, I found one site but I'm pretty sure it won't shit to US.

This being my 1st grow, I really want to keep it as simple as possible, but I will look into the supercropping & other suggestions & am considering a lot more options for my next grow.

At 6 days 12/12 what is the worst case scenario if I top 2 of them?

Whats canopy hight now and whats your max hight not counting the light gap?

Very worst case is some stunted growth and no main colas.

I have 24" for plant only, 36" for plant+bag, 54" from floor to glass at max height, and 67" from floor to ceiling.

When plants are topped a bit earlier, how long before the "main cola" area topped is replaced by the remaining "tops" forming multiple "main colas"? Did that make sense??

If I am missing the main cola, approx how much will that reduce my harvest?

So you still didnt say what hight the plant is now.

Topping or fimming can lead to multiple main colas(usually a lil smaller but more weight,depends on strain and pheno)if done in veg,but i think in flower the foliage has made all the node sites and will only fill them with buds.

Now im no pro but thats what i would think.

Also i noticed some reducing couplers( BIG NO NO)you will loose MAJOR air movement,when you can, use the largest size you can(your light is prolly 6" and you have alot of what looks like 4" duct and a 4" can fan reducing much of your cooling and filtering(which you will need alot of by the 5-8 weeks,you will see).

I have a 1K with 8" cooling and my buds are 12-16" from my light.

yes this is a good fungi,
A mycorrhiza (Greek for fungus roots coined by Frank, 1885^[1]; typically seen in the plural forms mycorrhizae or mycorrhizas) is a symbiotic (occasionally weakly pathogenic) association between a fungus and the roots of a plant.^[2] In a mycorrhizal association the fungus may colonize the roots of a host plant either intracellularly or extracellularly.
This mutualistic association provides the fungus with relatively constant and direct access to mono- or dimeric carbohydrates, such as glucose and sucrose produced by the plant in photosynthesis.^[3] The carbohydrates are translocated from their source location (usually leaves) to the root tissues and then to the fungal partners. In return, the plant gains the use of the mycelium's very large surface area to absorb water and mineral nutrients from the soil, thus improving the mineral absorption capabilities of the plant roots.^[4] Plant roots alone may be incapable of taking up phosphate ions that are immobilized, for example, in soils with an basic pH. The mycelium of the mycorrhizal fungus can however access these phosphorus sources, and make them available to the plants they colonize.^[5] The mechanisms of increased absorption are both physical and chemical. Mycorrhizal mycelia are much smaller in diameter than the smallest root, and can explore a greater volume of soil, providing a larger surface area for absorption. Also, the cell membrane chemistry of fungi is different from that of plants. Mycorrhizae are especially beneficial for the plant partner in nutrient-poor soils.
Mycorrhizal plants are often more resistant to diseases, such as those caused by microbial soil-borne pathogens, and are also more resistant to the effects of drought. These effects are perhaps due to the improved water and mineral uptake in mycorrhizal plants.
Mycorrhizae form a mutualistic relationship with the roots of most plant species (although only a small proportion of all species have been examined, 95% of all plant families are predominantly mycorrhizal).^[6]
Plants grown in sterile soils and growth media often perform poorly without the addition of spores or hyphae of mycorrhizal fungi to colonise the plant roots and aid in the uptake of soil mineral nutrients. The absence of mycorrhizal fungi can also slow plant growth in early succession or on degraded landscapes.
as for the hollow stems, all mj plants have it, & i dont even know or even heard of anyway to regulate the size of the hollow part.

prob the tops wont flower correctly, or only produce small colas. if your gonna top do it now. supercropping is fairly easy, its just "breaking" them stem just right where the stem falls over, like it was tied down. google it, or even youtube

from the looks in that pic, u should be able to tie them over

http://forum.grasscity.com/absolute-...made-easy.html it may take up to a wk, since in flower. thats hard to say, it might or might not effect your yeild, by topping & not having that main cola, the plant will pull its energy from that main cola & put into other buds.

On average 2 months veg and 2 month flower how many plants would a 400W HPS grow from start to finish and a 600W HPS?

The plants themselves are 24" tall minus the pot....36" tall with the pot.

As far as the reducers fan setup, I am only running the speed control at 50% right now which seems to run the fan at about 25% of capacity. I also have a 4" inline booster fan for later if needed....I figure I can use it on the intake or exhaust as needed later. When I was buying stuff for setting up I was asking about the reducers effect (other threads & sites) & was told I'd be fine, so if things get crazy hot or moist later I'll have to deal with it then.

Are you more concerned with heat or moisture? Because of the width of my plants I have my 400w HPS at about 20" so I can get light to all the far edges...I'm actually running a small heater to keep temps up in the room....between my 6" clip-on fan & the scrubber I cant keep the room over about 70-72 degrees without the heater because it's all cement walls in the room in the basement.
