FIRST GROW BOYS!!! i could really use some help

would personally do 400 watt perfect for 4 plants and will be easy to cool with your inline fan, if u go 600 u will need a bigger fan. but i dont like that it is a wing reflector, try get a cool tube much better idea

Hi Mike! thanks for the advice . I plan on doing a bigger grow in the future, I'm just doing 4 plants as a trial run. Do you think i should invest in a 600W light with a cool air tube? or just stick with 400w for now since i'm using a tent? along with the inline air duct fan i'm going to be using a tower fan and a floor fan do you think that will help much? ughhh, There's so many little things to this it's crazy ! i'm glad they're nice people here on the forum willing to help

If your thinking your going bigger in the future go 600s and cooltubes are a great choice

if you do go 400W, tryand get some of the "new" 400W ceramic metal halide jobbies...

Go with a 600 and an adjustable reflector. It's not that much more.

Then when you go bigger you can get a 400 to run a MH off of to broaden your spectrum.

Hear good things about 400W CMH

Don't forget odor control. A 440CFM can fan, one of those nice Gotham carbon filters; all sized to a 6" outlet size, couple of bungee cords, some light chain and some 6" metallic dryer venting should be able to be sourced for around $200.

Please realize the bulbs for a 600 are 3X the cost of a 400 or 1000 watt bulb. Get a 1000W. Go big or go home. Cool tubes in the 6" variety will work inline with your fan and filter too. Cooltubes are cool.

Do urself a favor when it comes to the cooltube.. make sure its the 19" model.. I fucked up when orderin n ordered the 27" and I gotta have it diagonal in my cab bc with the flex ducting and 6"-4" reducers attached its to long to fit in my 40"x32".. good luck

If you're doing the Lucas formula, just buy the Micro for now. If you use my formula for DIY GH FloraBloom, the first correct DIY formula for GH FloraBloom in human history (I challenge anybody to challenge that claim), the Bloom component of the Lucas formula will cost you only $4 per gallon tops if you buy the salts in 50 gallon pails. At most , the initial outlay will be $300 with shipping but you will have a lifetime supply.
The formula is as follows: 385.71 grams Epsom salt
381.12 grams MKP (0-52-34 on the label)
35.66 grams Potassium Sulfate
2977.51 mL of warm pure water
Add a solid, shake, repeat three times. Make sure it is dissolved and dose as you normally would the GH FloraBloom as per Lucas ratio or whatever excites you. I'll tell you how to make FloraMicro next month. Cheers.

also paint ur buckets white. no one mentioned this. helps reflect heat from ur water. instead of bucket absorbing it.. will save many root problems down the road also u cud use coolers which is even better than painting.
