Thanks, Hydrogreen. The nitrogen thing during flowering is what I was accounting for. This, I think, is a little more extreme.

you want me to expose my flowering plants to light during their dark cycle???

I understand that there is supposed to be some yellowing of leaves during the last half of flowering. However, my leaves look "crispy" and burnt on the tips. My ph is 5.9-6.1. My ppm's have been gradually brought to 1500 into week 6. A little help??

thanks fellas

Can somebody with experience debunk/confirm some questionable advice I've recieved?? I was told that my plants process all the co2 they need in the first few hours of the day light. I would appreciate the help. Angry pot nerds, please take your smarmy, belittling arguments elsewhere. I just...

So, I'm going back to the open reflector as opposed to the air cooled ones because i dont want to run 2 fans or worry about a fire if the one for the light fails. My fan/filter will be triggered by a temp controller to conserve as much CO2 as possible. Just for redundancy...DOES ANYONE FIND...

Does it behoove me to use cfl's in conjunction with led's?

Thax everyone. Thanx b51, I just needed to confirm my suspicion.

So, I understand that under normal conditions, the size of the plants fruits are directly correlated to the size of the container/rootball. However, if I'm growing in a 6" PVC tube with NFT...and the roots just run right through the root cup and fill the tube, does it matter what size my net...

sank you, sensai

Okay, so same as my HPS?

Yeah, thanx fellas. I always adjust the hid's colser or further when I read the leaves but, with the utmost due respect, my question was HOW CLOSE TO THE CANOPY SHOULD MY 90w UFO's BE? I appreciate the feedback.

running a 250 HPS on a light rail @ 12" above canopy. I have 2 90w 3 wave LED ufo's for supplemental lighting but, cant find consistent info on height above canopy. Please, can someone advise me???

My roots are starting to look like dreadlocks. Why?

Please, people, I need large potent yields on a single cola. I've seen a couple of auto-flower strains that do this but, I want photo-period strains. Any direction is welcome. I'm growing indoor, DWC-spray combo.

Can anybody recommend an indoor strain that has bright pink or purple buds? I've searched with limited success and there are a lot that claim to be blue or purple and they just aren't except in a certain light. It doesn't have to be a huge producer. Thanks.

I'm fairly new at this as well but, recently i've learned that if you chop out all the underbrush and even the small sraggy buds from under the canopy, you get them back on the colas ABOVE or near the canopy. Just a thought. I'm sure genetics play a roll too.

GO TIGERS!...next year

Give yourself an extra 4 inches of bark at the base. Just like you were lollipopping the plant. Then pour a 3.5 inch layer of sand on the surface of the soil. You can sterilyze the sand by baking it for little while. i cant remember how long. You can easily find it though through google.
