630w LEC 4x4 tent Grow

What's up how they coming along under the 630? I get my second bulb in today . Can't wait on seeing her at 100% operating . This 630 is a beast for a 4x4 .

Just snapped a few pics. Last week they were getting over the transplant. This week there feeling better. I just did some lst to them this morning. I still have the 2 scraggly looking ones (also chocolope) to be honest the produced the most last crop...
The pre-flowers are tight and big!

Can't wait to see how this turns out

I love the sun sytem reflectors

The light is still pretty far away, but there not stretching and temps are 82-85° at the canopy. I need a way to bring more cool air in. I want to keep it under 80°f when i switch and it's only getting warmer here. But if you look at when the first got put in and now you can see they doubled in size.

You got a link to your grow?

Here's new pics. The tent is filling in. I have many tops on all my plants. I moved them around a little. The Jack is in the back middle. As you can see two are still scraggly pains in my ass.

What is your daily low temperature during lights off?

As long as you have atleast a ten degree day/night differential you should be good

Yeah. It is. Some nights are cooler, in the 60's. I would like to have flower temps around 75° w/lights on and 55°off. I'll probably give it another week or so of veg.

I think once plants get below around 60 degrees they start growing slower than their full potential. Have some plants in early veg and the canopy was only getting to 75, they lost turgor and started drooping, basically the plant wasn't able to use the water because it wasn't hot enough.

I agree. I like 55° or so the last week of flower with lights off when possible.

looks great just used the 630w lec but different fixture, expect great results. any plans to scrog?
alot of truth to the earlier harvest too as everyone else said btw

Thanks for checking in! I scroged last round because the tent size was an issue this time im just letting them go. I have extra room to fill out. I will probably be swithing early next week.

I never had pistils show up before flowering was introduced?! (See pic 1)

Tight! (See pic 2)

Looking good in there, wait until you see how fast they transition into flowering and mature compared to other techs. It took me a couple of rounds to get used to the fast maturation rate.

As you can see there is still room in the tent. I haven't raised the light any. Plenty of room to fill in. Lots of growth under the canopy might trim some of the smaller stuff before swithing over.

Hello Bigpuffer !
What a beautiful growroom !!

I'm actually looking to change my light set up to something with more efficiency than HPS, like LED or LEC.

I all ready have good results but i want to improve like everybody i think !

I stay no far from here to check the evolution !

Good grow man !

Product Description
This is the complete Ceramic MH fixture that comes with ballast, bulb, and reflector. The Cycloptics reflector comes with a 6 foot lamp cord. Plug and play ready to go out of the box. The Philips 3100k Agro is recommended if this will be your primarily light for the flowering phase of growth.

Greenbeams can be used in both small and large scale grow room applications. Depending on the level of light required, we can determine the optimal number of lights required to meet your needs, while maintaining the best spectrum and highest levels of uniformity.

Philips Green Power 315W CMH Spectrum Philips originally developed this lamp for Cycloptics. It is the most efficient lamp in producing photosynthetic photon flux (PPF) per watt. As tested at Utah State University Crop Physiology Laboratory its spectrum is 18% and 44% more efficient for photosynthesis than MH and HPS lamps respectively.

Full Volume 3D Uniformity
All-Bright and Greenbeams indoor lighting systems deliver superior light uniformity over the full volume of a grow room with greater intracanopy light penetration than horizontal lamp reflectors. "Hot spots" are eliminated too, because 90% of the light reflects off the walls and lands on the plants from multiple angles. The Cycloptics Greenbeam's geometry assures that less than 3% of the lamp's rays are trapped by the lamp as they reflect in One Bounce and OutTM off of the reflector's 95% reflective aluminum. This is far superior to horizontal lamp reflectors. They trap up to 20% of the lamp's light inside the reflector in the form of heat, which is the primary cause of horizontal lamp failures.

• Exceptional uniformity over the full volume of the grow room
• Reduces electricity usage by up to 70%
• Reduces grow room temperatures
• Increases yield while reducing operating expenses
• Another great item from Flora Hydroponics

has anyone seen this new ceramic lamp?? i just may have to buy another... what you guys think of this one as compared to the sun system or the boulder lamp co. 315 watt lec's???
